Your Winter Project

The Suzuki Hayabusa has long been considered one of the most desirable motorcycles to turbocharge, thanks to its robust 1340cc engine and the extensive aftermarket support available for performance upgrades. Riders are drawn to the Hayabusa’s ability to handle significant horsepower increases, but one common hesitation for street riders is the perceived need to install a base spacer to lower compression from around 12:1 to 9:1. This modification is often recommended for high-boost setups, as reducing compression helps prevent detonation under heavy turbo pressure.

However, to combat this, ProBoost offers a Low-Boost turbo kit in addition to its Street and Race kits designed specifically for stock-compression Hayabusas. This kit limits boost to 4–5 psi, a level that the engine can safely handle without internal modifications. The key lies in how the kits are engineered to control and cap boost pressure.

How Low-Boost Kits Work

Wastegate Control: A properly sized external wastegate (commonly 38 mm) ensures that excess exhaust gases bypass the turbo once the target boost level is reached. This mechanical safeguard prevents boost creep beyond 4–5 psi.

ECU Tuning: Kits often include standalone or piggyback ECU systems with maps calibrated for low boost. These maps adjust ignition timing and fuel delivery to prevent detonation at stock compression.

Fuel System Upgrades: Even at low boost, additional fuel is required. Requires upgraded fuel pump and potentially upgraded regulator, and injectors to maintain the correct air-fuel ratio.

MAP Sensors & Boost References: A map sensor or similar device ensures the ECU accurately reads boost pressure and responds accordingly.

Reliability of 4–5 PSI Kits

It has been proven that stock-compression Hayabusas can reliably run 4–5 psi without engine damage, provided the kit is installed correctly and tuned properly. At this level, the engine typically produces 230–250 horsepower, a significant increase over stock while maintaining long-term reliability. The low boost avoids the extreme cylinder pressures that necessitate compression-lowering spacers.

Reliability hinges on three factors:
Consistent wastegate function to prevent boost spikes.
Proper ECU calibration to avoid lean conditions or detonation.
Routine maintenance of turbo components, fuel system, and sensors.

Conclusion

In short, low-boost turbo kits for the Hayabusa achieve safe performance gains by mechanically and electronically capping boost at 4–5 psi. This allows street riders to enjoy substantial horsepower increases without the expense and complexity of lowering compression. As long as the wastegate, ECU, and fuel system are functioning correctly, these kits are reliable and will not exceed the intended boost level.

Additionally street riders benefit with the ProBoost turbo kit because the kit uses the stock oil cooler and rad, so that normal use of street and highway riding keeps your Hayabusa purring and running without issue.

Motorcycle Ice Racing

Motorcycle ice racing is one of the most unique and thrilling forms of motorsport, combining winter landscapes with high-speed competition on frozen lakes and rivers. Riders fit their motorcycles with studded or spiked tires, transforming slippery ice into a racing surface with remarkable traction. This sport has a rich tradition in Scandinavia and Canada, and continues to grow in North America under the sanction of major organizations.

Riding on Ice: Who Does It?

Ice racing attracts a diverse group of riders. Many are flat track racers who use ice racing as off-season training, since the studded tires provide grip comparable to dirt or asphalt. Others are enthusiasts from northern regions where frozen lakes are abundant, turning winter into an opportunity rather than a barrier. Riders range from amateurs experimenting with local club events to professionals competing in international championships.

The Motorcycles Used

The motorcycles typically used for ice racing are off-road bikes such as motocross or flat track machines, modified with studded tires and protective fenders. These spikes—hundreds of razor-sharp screws embedded into the tires—allow riders to lean at extreme angles without losing grip. Some bikes are lowered for stability, while others retain their dirt-track geometry for versatility. In Europe, specialized ice speedway bikes are common, featuring rigid frames, no brakes, and long spikes for maximum traction.

Competitions and Upcoming Events

Globally, the most prestigious competition is the FIM Ice Speedway World Championship, sanctioned by the Fédération Internationale de Motocyclisme (FIM). The 2025 calendar includes qualifying rounds in Sweden (Örnsköldsvik, February 1), Germany (Inzell, March 15–16), and the Netherlands (Heerenveen, April 5–6). These events showcase the best riders from Scandinavia, Russia, and Central Europe.

In North America, the American Motorcyclist Association (AMA) sanctions ice racing events across northern states. Canada also hosts a vibrant scene, with the CASC Ontario Region and clubs like the Winnipeg Sports Car Club organizing annual ice racing schedules. Local ovals and grand-prix style courses are plowed onto frozen lakes, creating competitive circuits for both rookies and veterans.

Sanctioning and Sponsorship

Ice racing is formally sanctioned by organizations such as the AMA in the U.S., the Canadian Motorcycle Association in Canada, and the FIM internationally. These bodies provide rulebooks, licensing, and championship structures. Sponsorship often comes from motorcycle manufacturers, gear companies, and local businesses, especially in regions where ice racing is a cultural tradition.

Popularity in North America and Beyond

In North America, ice racing remains a niche but passionate sport. It is particularly strong in Canada, where frozen lakes provide natural venues and communities embrace winter motorsports. Events in Ontario, Manitoba, and Alberta draw consistent participation. In the U.S., northern states like Minnesota, Wisconsin, and Michigan are hotbeds of activity.

In Scandinavia and Finland, however, ice racing is far more mainstream. Finland, Sweden, and Russia have produced world champions, and the sport enjoys strong cultural support. The long winters and tradition of motorsport make ice racing a natural fit, with large crowds attending FIM-sanctioned events.

Conclusion

Motorcycle ice racing is a fascinating blend of skill, engineering, and winter endurance. From studded motocross bikes on frozen lakes in Canada to specialized speedway machines in Scandinavia, the sport thrives under the sanction of organizations like the AMA and FIM. While it remains a niche discipline in North America, its popularity in Canada and Europe ensures that ice racing continues to be one of the most spectacular winter motorsports. With upcoming events in Sweden, Germany, and the Netherlands, and local races across Canada and the U.S., the 2025 season promises to keep the tradition alive and growing.

Slow-Mo of That Point You Fall Off Your Motorcycle

Suzuki Hayabusa Fuel Pump and Filter Maintenance: A Deep Dive

The Suzuki Hayabusa is a motorcycle that has earned legendary status in the performance world. Known for its blistering speed, smooth power delivery, and bulletproof engineering, it remains a favorite among riders who demand both reliability and adrenaline. Yet, like any high-performance machine, the Hayabusa requires careful attention to its fuel system. At the heart of that system lies the in-tank fuel pump and filter assembly—a component often overlooked until problems arise. Proper maintenance of this system is critical, not only for everyday street riding but especially for those who push the limits with turbochargers, nitrous oxide, or heavily built engines. In this article, we’ll explore the three key issues surrounding Hayabusa fuel pump maintenance, why the filter is the most important factor, and how external filter solutions and pump upgrades can save you headaches down the road.

Clean Fuel Tank: The First Line of Defense
The first and most fundamental issue in fuel pump maintenance is the condition of the fuel tank itself. A clean tank is essential because the pump and filter are only as effective as the environment they operate in. Dirt, rust, and debris inside the tank can wreak havoc on the fuel system. Even small particles can clog the filter, reduce fuel flow, and eventually damage the injectors. Rust is particularly insidious; once it begins forming inside the tank, it tends to spread and flake off, contaminating the fuel supply continuously.

For Hayabusa owners, regular inspection of the tank is a must. If the bike has been stored for long periods, especially with fuel inside, condensation can lead to rust formation. Riders should periodically drain the tank, inspect the interior with a flashlight, and flush it with clean fuel if necessary. Preventative measures, such as using fuel stabilizers during storage and keeping the tank full to minimize air exposure, can go a long way toward preserving the integrity of the system. A clean tank ensures that the pump and filter are not fighting a losing battle against contamination.

Fuel Pump Wear: Recognizing When It’s Beyond Its Prime
The second issue is the pump itself. Like any mechanical component, the fuel pump has a finite lifespan. Over time, wear and tear reduce its efficiency. For a Hayabusa with high mileage, the pump may simply be beyond its prime. Symptoms of a failing pump include difficulty starting, inconsistent fuel delivery, hesitation under acceleration, or outright stalling. Riders often mistake these issues for electrical problems or injector faults, but the pump is frequently the culprit.

The Hayabusa’s in-tank pump is designed to deliver consistent pressure to the injectors, but once its internal components wear down, it struggles to maintain that pressure. This is especially problematic for performance riders who demand more fuel flow than stock conditions. A tired pump may still function under normal riding, but when asked to support a turbocharged or nitrous-fed engine, it quickly reveals its limitations. Replacing the pump before it fails completely is wise preventive maintenance. Bosch pumps, for example, are a popular upgrade among Hayabusa enthusiasts. Known for their reliability and strong flow characteristics, Bosch units provide peace of mind when pushing the bike beyond factory specifications.

The Fuel Pump Filter: Small but Critical
The third and arguably most important aspect of fuel pump maintenance is the filter. On the Hayabusa, the in-tank filter is notoriously small. While compact design may have been convenient for Suzuki engineers, it presents a major problem for riders. When this tiny filter clogs, fuel delivery is impeded, and the engine suffers. Poor throttle response, lean conditions, and even engine damage can result from inadequate fuel supply. In performance applications, a clogged filter is not just inconvenient—it’s dangerous.

The challenge lies in the fact that OEM replacement filters are difficult to source, and aftermarket options vary widely in quality. Riders often find themselves stuck between expensive OEM parts and questionable third-party alternatives. Worse, the in-tank design makes cleaning or replacing the filter a tedious process. For these reasons, many experienced Hayabusa owners have adopted a more practical solution: bypassing the in-tank filter entirely and installing an external filter.

External Filter Solutions: Practical and Effective
Bypassing the in-tank filter and running an external unit offers two major benefits. First, external filters are far easier to clean and replace. Riders can visually inspect them, remove them quickly, and flush them without disassembling the tank. This convenience alone makes the modification worthwhile. Second, external filters provide assurance that when the pump is running, the injectors are receiving the fuel they need. With the restrictive in-tank filter out of the equation, fuel delivery becomes more consistent and reliable.

Another advantage is flexibility. External filters come in a wide range of sizes and flow ratings, allowing riders to tailor the system to their specific needs. Whether you’re running a stock engine or a turbocharged monster, you can select a filter that matches your fuel demands. This customization is critical for performance builds, where fuel starvation can spell disaster. Riders who adopt external filters often report smoother throttle response, fewer maintenance headaches, and greater confidence in their bike’s reliability.

Bosch Pump Upgrade: A Proven Performer
As mentioned earlier, Bosch pumps are a popular choice for Hayabusa owners seeking an upgrade. These pumps are well-regarded in the automotive and motorcycle communities for their durability and flow capacity. When paired with an external filter, a Bosch pump transforms the Hayabusa’s fuel system into a robust, high-performance setup. Riders who add nitrous, turbochargers, or superchargers often consider this upgrade mandatory. The stock pump simply cannot keep up with the demands of forced induction or heavily modified engines.

Bosch pumps also offer peace of mind for long-distance riders. Even if you’re not chasing horsepower records, knowing that your fuel system is equipped with a reliable pump and filter setup reduces the risk of being stranded by a fuel delivery failure. For a bike like the Hayabusa, which is often ridden hard and fast, reliability is not optional—it’s essential.

Street Riders vs. Performance Builders: Different Needs, Same Lesson
It’s worth noting that many street riders overlook fuel pump maintenance. Because the Hayabusa is so well-engineered, it often runs flawlessly for years without attention to the pump or filter. However, this complacency can lead to sudden problems. Even riders who never plan to add performance modifications should inspect and maintain their fuel system regularly. A clogged filter or failing pump doesn’t discriminate between stock and modified bikes—it will cause issues regardless.

For performance builders, the lesson is even more critical. Fuel delivery is the lifeblood of any high-horsepower engine. Without adequate fuel, even the most carefully tuned setup will fail. Upgrading the pump and filter is not optional—it’s mandatory. Riders who invest in turbo kits, nitrous systems, or superchargers must also invest in a fuel system that can support those modifications. Ignoring this step is a recipe for blown engines and wasted money.

Conclusion: Fuel System Maintenance as Preventive Medicine
In summary, the Suzuki Hayabusa’s in-tank fuel pump and filter system demands attention. The three key issues—keeping the tank clean, recognizing when the pump is worn out, and addressing the limitations of the tiny in-tank filter—form the foundation of proper maintenance. By bypassing the restrictive OEM filter and installing an external unit, riders gain convenience, reliability, and peace of mind. Pairing this setup with a Bosch pump ensures that the Hayabusa’s legendary performance is backed by a fuel system capable of meeting any demand.

Fuel pump and filter maintenance may not be glamorous, but it is essential. Street riders benefit from reliability and smoother performance, while performance builders gain the assurance that their engines are properly fed under extreme conditions. In both cases, the lesson is clear: don’t overlook the fuel system. The Hayabusa deserves the best, and with proper care, it will continue to deliver the speed, power, and thrill that made it a legend.

Number One Difference Between Harleys and Sport Bikes

The Power Band Divide: Harley Cruisers vs. Sport Bikes

Motorcycle culture is built on passion, identity, and the visceral thrill of twisting the throttle. Yet, if there is one defining line that separates Harley-Davidson cruisers from sport bikes, it is the power band—the way each machine delivers its strength to the rider. This difference is not subtle; it is the very heartbeat of the two worlds, shaping how they sound, how they feel, and how they demand to be ridden.

Harley-Davidson cruisers are torque monsters. Their engines are tuned for low-end grunt, delivering a surge of raw pulling power the moment you ease off the clutch. That sensation of being shoved forward from a stop sign or rolling out of a corner is intoxicating. It’s not about speed—it’s about force. The deep, throaty rumble of a Harley’s V-twin is more than just noise; it’s a statement. It’s rough, tough, and mean, resonating through your chest like a war drum. Riders don’t need to chase redlines or scream through gears to feel rewarded. The satisfaction is immediate, accessible, and deeply primal.

Sport bikes, on the other hand, live at the opposite end of the spectrum. Their engines are designed to spin high, often soaring past 12,000 RPM before hitting peak power. The experience is one of zinging acceleration, winding through gears, and chasing the rush that only comes at blistering speeds. Some sport bikes sound strained and gasping as they climb the rev range, while others—especially the high-end machines—sing with a symphony that rivals exotic cars, like a Ferrari on two wheels. But the catch is clear: the reward only comes when you push hard, when you ride fast, and when you dance dangerously close to the limits of the law. Around town, that means temptation. It means radar traps, unmarked cars, and speeding tickets waiting to punish the thrill. This contrast in power delivery creates two entirely different riding experiences. On a Harley, the joy is in the torque—the immediate, low-end surge that makes everyday riding satisfying without breaking the speed limit. On a sport bike, the joy is in the chase—the high-rev scream that demands velocity, precision, and risk. One is about raw muscle and attitude, the other about razor-sharp performance and adrenaline. Both are intoxicating, but in opposite ways.

Ultimately, the greatest difference between Harley cruisers and sport bikes is not just mechanical—it’s philosophical. Harleys reward patience, presence, and the simple act of rolling away with authority. Sport bikes reward aggression, speed, and the pursuit of perfection at high RPMs. One thrives in the city streets, the other on open highways and racetracks. Together, they represent two sides of the same coin: the eternal allure of motorcycles, each with its own rhythm, its own voice, and its own way of making riders fall in love.

Long-Term Motorcycle Storage Guide

Keep Your Motorcycle Safe Over the Winter

Properly storing a motorcycle for an extended period, such as over a winter season, requires diligent preparation across several key areas to ensure the bike remains in optimal condition and is ready to ride when the next season arrives. The ideal storage environment is clean, dry, and temperature-controlled, like a well-ventilated garage or a dedicated storage unit, which helps protect mechanical and electrical components from extreme temperatures and dampness that can lead to rust and deterioration. Before storage, a thorough wash and dry of the motorcycle is essential to remove all dirt, road grime, and moisture, followed by applying a protective wax or a dedicated anti-corrosion lubricant to all painted, chrome, and metal surfaces to prevent rust and pitting.

Battery Care and Maintainer Usage

The battery is one of the most crucial components to manage during long-term storage. The best way to maintain it is by using a "smart" battery tender (also often called a battery maintainer or trickle charger) designed for motorcycles. Unlike basic old-school trickle chargers, smart tenders are microprocessor-controlled and feature multi-stage charging, which automatically switches from a full charging mode to a float or maintenance mode once the battery is full. This prevents overcharging, which can boil the battery's fluid and damage its internal plates, ultimately shortening its lifespan. Brands like Battery Tender (e.g., Battery Tender Plus, Battery Tender Junior), OptiMate, and NOCO Genius are highly regarded for their reliability and advanced technology, often offering models that can handle both traditional lead-acid (flooded, AGM, Gel) and newer Lithium (LiFePO4) batteries.

The tender should be used continuously for the entire duration of the storage period. It is designed to be left connected for weeks or months, monitoring the battery's voltage and delivering only the necessary charge to keep it topped up and prevent the damaging process of sulfation that occurs when a battery self-discharges. To use it, simply connect the tender's quick-disconnect harness (which should be permanently installed on the battery terminals for convenience) and plug the tender into a wall outlet. For optimal care, some recommend removing the battery entirely and storing it in a dry, room-temperature location, especially if the storage area is prone to freezing, but connecting the tender directly to the bike in a secure location is a common and acceptable practice, provided the tender is a modern smart-style maintainer.

Fuel System Preservation

Another critical step is preparing the fuel system, as modern gasoline, especially ethanol-blended fuel, degrades rapidly and can cause gum and varnish deposits that clog carburetors and fuel injectors. The best approach is to fill the fuel tank completely to the brim, which minimizes the air space inside and reduces the chance of moisture condensation and internal tank rust. Crucially, a fuel stabilizer must be added to this full tank. Popular and effective brands include Sta-bil, Star Tron Enzyme Fuel Treatment, and Seafoam. The stabilizer should be added according to the product's instructions, and the engine must then be run for about 10–15 minutes. This circulation ensures the treated fuel moves through the entire fuel system, the tank, petcock, fuel lines, fuel pump, injectors, and/or carburetor to protect all components from degradation.

Tire and Chassis Considerations

To prevent flat spots, which can develop when a motorcycle's weight rests on the same section of the tires for months, it is highly recommended to lift the motorcycle. Using front and rear paddock stands, a center stand, or a motorcycle jack to get the tires completely off the ground is the best solution. If lifting the bike is not possible, you should at least inflate the tires to the maximum PSI listed on the sidewall of the tire itself (not the riding pressure listed in the owner's manual). This over-inflation helps the tire maintain its round shape under the bike's load. Additionally, placing a barrier like a piece of cardboard, carpet, or a rubber mat under the tires can help insulate them from the cold, damp concrete floor.

Protective Coatings and Final Steps

For added protection against corrosion, many riders advocate for spraying exposed metal and chrome surfaces with an anti-corrosion agent. While WD-40 is a water-displacing spray and can provide a temporary moisture barrier, it is primarily a solvent and not a long-lasting rust inhibitor or lubricant. A better, more detailed method is to clean the bike, apply a quality wax to painted parts, and use a dedicated silicone spray or a rust inhibitor product on non-painted metal surfaces. Some professionals suggest lightly spraying inside the exhaust pipes and then plugging the openings with a rag or a specialized exhaust plug to prevent moisture and rodents from entering. Finally, cover the entire motorcycle with a breathable, non-plastic motorcycle cover to protect against dust while allowing moisture to escape, preventing condensation and mildew formation.

Best Turbo Bike Ever Made - Hayabusa Gen2

The Gen2 Hayabusa: The Ultimate Platform for Turbo Power

The Suzuki Hayabusa Gen2 (2008–2020) has cemented its legacy not just as a high-speed icon, but as arguably the ideal motorcycle platform for turbocharging, particularly for the dedicated street racer. The synergy of the Gen2's robust engineering and the straightforward nature of its electronics, compared to the modern Gen3, makes it a prime candidate for massive power gains. For riders looking to tap into a new level of performance without breaking the bank, a system like the Proboost Turbo Kit is a game-changer.

💪 Engineering Advantage: Built to Boost

One of the most compelling reasons for the Gen2 Hayabusa's turbo suitability lies in its legendary engine strength. The 1,340cc inline-four engine is renowned for its durability and stout internals, capable of handling significant increases in horsepower with minimal or no internal modifications at lower boost levels. For context, while the stock engine produces around 190 horsepower, installing a turbo kit can immediately vault the rear-wheel power output well over the 300 horsepower mark on pump fuel, with some builds reaching over 450 horsepower with internal engine work and race fuel. This robust foundation, which includes a strong crankcase and connecting rod design, allows street riders to bolt on a turbo and experience explosive acceleration without the immediate need for a costly engine rebuild, a major financial and time advantage over many other sport bikes.

🛠️ Simplicity and Cost-Effectiveness: The Gen2 Edge

Unlike its more electronically complex Gen3 successor, the Gen2 lacks much of the intricate electronic rider aids (like a sophisticated IMU and multiple complex ride modes) that complicate forced-induction tuning. This relative electronic simplicity translates directly into easier installation and tuning, making the process more accessible and generally less expensive. The Gen2’s simpler architecture means fewer systems need to be bypassed, integrated, or tricked into handling the huge power increase. This ease of use is a significant factor in the growing appeal of turbocharged Gen2 'Busas among the street racing community, where riders often prefer wrenching on their own machines or having straightforward aftermarket support.

Harley V-Rod and Supercharger Tuning

Vrod + Supercharger + ThunderMax

For a supercharged V-Rod, the best engine control unit (ECU) is generally a full, standalone system like the ThunderMax with auto-tune technology, or an advanced flash tuner like the Dynojet Power Vision. Unlike a simple piggyback tuner, these options offer the level of control necessary to safely and effectively tune a forced-induction engine.

Here is a breakdown of the top options:

1. ThunderMax EFI Tuner (full ECM replacement)

This is widely considered the gold standard for Harley tuning, especially for significant engine modifications like a supercharger.

Pros:

Full ECM replacement: The ThunderMax completely replaces the stock ECU, giving you total control over all engine parameters.

Integrated auto-tune: It uses wideband oxygen sensors to continuously and automatically tune the air-fuel ratio (AFR) for optimal performance in all conditions. This is a massive advantage for a supercharged motor, as it simplifies the tuning process and keeps the engine safe.

Customizable: Allows for advanced adjustments to ignition timing, idle speed, and more

Cons:

High cost: It is the most expensive option, but the price reflects its advanced capabilities.

Learning curve: While the auto-tune feature is easy, mastering all the features requires some technical skill.

2. Dynojet Power Vision (flash tuner)

The Power Vision is an excellent, user-friendly flash tuner that is also very capable for supercharged V-Rods.

Pros:

Comprehensive tuning: It flashes the stock ECU, giving you control over ignition, fuel delivery, and more.

Intuitive interface: The full-color touchscreen makes data monitoring and tune flashing very easy.

Supports auto-tune: When paired with the optional Target Tune wideband module, it can achieve a tuning strategy similar to the ThunderMax.

Cons:

Requires extra hardware for full auto-tune: You need to purchase the Target Tune module and its wideband sensors to get the best automatic tuning features.

3. Dynojet Power Commander (piggyback tuner)

For riders on a budget, a Power Commander can work, but it offers less control than a full replacement ECM or flash tuner.

Pros:

Cost-effective: It is much less expensive than a full ECM replacement.

Easy to install: It plugs directly into the factory harness and does not require flashing the stock ECU.

Cons:

Limited control: It works by modifying the signal from the stock ECU rather than directly controlling the engine. This makes it less ideal for the demands of forced induction.

Requires manual dyno tuning: To get the best results for a supercharged engine, a professional dyno tune is necessary. It lacks the advanced auto-tuning capabilities of the Power Vision with Target Tune or the ThunderMax.

Front Fork Adjustment Suzuki Hayabusa

Getting the correct ride is very important. Some riders like firm, but if front forks are too firm they can be close to unrideable without you knowing it. Good to do a little maintenance. Improving the ride quality of your Suzuki Hayabusa’s front suspension involves adjusting the three main parameters: Spring Preload, Rebound Damping, and Compression Damping.

The Hayabusa typically comes with fully adjustable inverted telescopic forks, meaning you have adjusters for all three on the front forks.

Suspension tuning is highly personal and depends on the rider’s weight, gear, riding style, and the roads they ride on. Always refer to your Hayabusa Owner’s Manual for specific locations of the adjusters, tool requirements, and the factory baseline settings (usually in “clicks out” from fully tightened). Record your current settings before making any changes.

Here is a detailed, step-by-step process for adjusting the front suspension:

1. Setting Sag (Spring Preload Adjustment)

Purpose: Preload adjustment is the first and most critical step. It determines the correct ride height of the bike by adjusting the initial compression of the spring. This is essential for ensuring the suspension operates within its optimal range of travel.

Softer Ride: Generally requires less preload (more sag).

Firmer Ride: Generally requires more preload (less sag).

Steps:

Preparation: Put on all your usual riding gear (helmet, jacket, etc.). Have two friends available to help with measuring and stabilizing the bike. You will need a tape measure (metric preferred) and the appropriate tool for the preload adjuster (often a hex key or a C-spanner).

Measure Fully Extended Length (Zero Sag): Lift the front of the bike until the front wheel is completely off the ground and the suspension is fully extended. Have one person hold it stable. Measure the exposed part of the inner fork tube (from the bottom of the fork dust seal to the bottom of the triple clamp, or a consistent point near the axle—choose a clear reference point and use it for all measurements).

Measure Rider Sag: Sit on the bike in your normal riding position (feet on pegs). Have one helper balance the bike from the rear. The second helper should push down gently on the front end and let it rise slowly, then measure the same reference points.

Calculate Sag:

Target Sag: For a sport bike like the Hayabusa, a common starting target for street rider sag is usually around 25mm to 35mm (or about 1/4 to 1/3 of the total suspension travel). Check your manual for specific recommendations.

Adjust Preload:

If Sag is too high: Increase preload by turning the adjuster (usually a hex bolt or cap on the top of the fork tube) clockwise (in). This compresses the spring more, raising the front end and reducing sag.

If Sag is too low: Decrease preload by turning the adjuster counter-clockwise (out). This lessens spring compression, allowing the front end to drop more and increasing sag.

Re-Measure: Repeat steps after each adjustment until you are close to your target sag.

Adjusting Damping

Damping controls the speed at which the suspension compresses and extends. It is adjusted using “clickers” and is measured in “clicks out” from the fully tightened position.

Rebound Damping

Purpose: Controls the speed at which the fork extends after hitting a bump.

Softer Ride (Faster Rebound): Turn adjuster counter-clockwise (out) to decrease damping. This allows the fork to extend back faster, which can improve comfort over a series of quick bumps, but too fast can cause the bike to “pogo” or feel unstable.

Firmer Ride (Slower Rebound): Turn adjuster clockwise (in) to increase damping. This slows the extension of the fork, which improves control, especially during hard acceleration or after compression, but too slow can cause the suspension to “pack up” (not fully extend before the next bump), leading to a harsh ride.

Steps:

Locate Adjuster: Usually found on the top of the fork cap.

Find Baseline: Turn the adjuster all the way clockwise until it stops (don’t force it) and count the total number of clicks as you turn it out. Set it back to the factory/stock setting from your manual.

Test and Adjust: Ride the bike over a known test route. Adjust in increments of 1 to 2 clicks at a time.

Symptom: Front end bounces multiple times after a bump (pogoing): Increase rebound damping (turn in).

Symptom: Harsh ride, front wheel “packing up” or feeling like it won’t track the ground over a series of bumps: Decrease rebound damping (turn out).

Compression Damping

Purpose: Controls the speed at which the fork compresses into a bump or under braking.

Softer Ride (Less Compression Damping): Turn adjuster counter-clockwise (out) to decrease damping. This allows the fork to compress more easily, resulting in a plusher ride over small bumps, but too little can cause excessive dive under braking or bottoming out.

Firmer Ride (More Compression Damping): Turn adjuster clockwise (in) to increase damping. This makes the suspension stiffer and more resistant to compression, improving control during hard cornering and braking, but too much leads to a harsh ride that can transmit every small bump.

Steps:

Locate Adjuster: Often found on the bottom of the fork leg near the axle.

Find Baseline: Turn the adjuster all the way clockwise until it stops and count the total number of clicks as you turn it out. Set it back to the factory/stock setting.

Test and Adjust: Ride the bike over your test route. Adjust in increments of 1 to 2 clicks at a time.

Symptom: Excessive front-end dive during braking or bottoming out over large bumps: Increase compression damping (turn in).

Symptom: Harsh ride over small, sharp bumps (feels like hitting a brick): Decrease compression damping (turn out).

How To Adjust the Boost on a Supercharger

To adjust the boost on a TTS supercharger, you typically change the size of the supercharger's pulley; a smaller pulley increases boost by spinning the supercharger faster, while a larger pulley decreases it. For some TTS systems, adjustments may be made through a variable boost control dial or by changing the size of the crank pulley instead of the supercharger's pulley.

Pulley size adjustment

Smaller supercharger pulley: Installing a smaller pulley on the supercharger will increase boost pressure because the supercharger will spin faster for every rotation of the engine's crankshaft.

Larger supercharger pulley: A larger pulley will decrease boost pressure, as it spins slower for each engine crankshaft rotation.

Changing the crank pulley: An alternative to changing the supercharger pulley is to swap the crank pulley. A larger crank pulley will also increase boost, while a smaller one will decrease it. However, this method can affect other components driven by the crank pulley, so it requires careful consideration.

Boost Sensor for Supercharger

A boost sensor is often included in a TTS supercharger kit, or is a necessary component for its installation to monitor and control boost pressure. The sensor is crucial for the engine's control system and may be a part of the kit to ensure proper performance and engine safety.

Function: A boost pressure sensor measures the pressure in the engine's intake manifold, which is generated by the supercharger. This data is used by the engine's computer to manage the amount of boost being produced, which affects air pressure and fuel delivery.

Necessity: While the supercharger itself provides the boost, a sensor is needed to make sure it doesn't exceed safe limits and to fine-tune the engine's performance.

Kit contents: Check the specific TTS supercharger kit for the vehicle you have, as the sensor and other necessary components (like gauges or other sensors) can vary between applications.

A boost sensor to read the supercharger's output. This is the Manifold Absolute Pressure (MAP) sensor, which is crucial for the engine's computer (ECU or PCM) to monitor and control boost levels for optimal performance and fuel mixture. You can use an aftermarket gauge, such as a P3 gauge, to display this information.

How it works

The MAP sensor is located between the supercharger and the engine, typically in the intercooler or intake pipe.

It measures the pressure of the compressed air coming from the supercharger.

This data is sent to the engine's computer, which uses it to calculate and adjust the air-fuel ratio.

How to see the boost reading

Use a scan tool or OBD-II gauge: A standard OBD-II scan tool or a dedicated boost gauge that connects to the OBD-II port can read the boost pressure from the vehicle's factory MAP sensor.

Install an aftermarket gauge: Many aftermarket gauges, like the P3 gauge, can display boost pressure by reading data directly from the vehicle's sensors or the ECU.

Consider analog or digital inputs: Some gauges offer options for analog inputs, which would require a separate boost pressure sensor to be installed in the intake piping. However, reading from the existing MAP sensor is often the easiest method.

Great Options - Great Price

Greetings, fellow gearheads and speed aficionados! It’s your humble servant, Jax “Sparkplug” Peterson, head of R&D at HardRider MotoWerks, here to take you on a deep dive into the electrifying present and even more thrilling future of motorcycle performance. We’re not just selling parts; we’re pushing boundaries, and let me tell you, the boundaries are getting wider, faster, and more exhilarating with every passing year.

The motorcycle landscape right now is a glorious tapestry of innovation. From the burgeoning electric revolution to the relentless refinement of internal combustion, it’s a golden age for two-wheeled enthusiasts. We’re seeing more sophisticated electronics than ever before – lean-angle sensitive traction control, advanced ABS systems that practically read your mind, and customizable riding modes that transform a street machine into a track weapon with the flick of a switch. These aren’t just luxuries; they’re foundational elements that allow us to extract more power safely and efficiently.

But let’s be honest, while the OEMs are doing fantastic work, you’re here because you want to know what we at HardRider MotoWerks are doing to turn “fantastic” into “ferocious.” And that, my friends, brings us to the holy trinity of forced induction and chemical enhancement: Nitrous, Turbochargers, and Superchargers.

Nitrous Oxide: The Instant Adrenaline Shot
Nitrous has always been the dark horse, the secret weapon for those seeking an immediate, visceral surge of power. It’s deceptively simple: a shot of N2O introduces more oxygen into the combustion chamber, allowing for a proportionally larger fuel charge and a resulting explosion of power. The beauty of nitrous is its instantaneity. No spooling, no lag – just pure, unadulterated acceleration.

At HardRider, we’ve moved far beyond the “dump-it-all-in” days. Our current generation of dry and wet nitrous systems features intricate progressive controllers that precisely meter the N2O flow based on throttle position, RPM, and even gear selection. This allows for incredibly smooth engagement, preventing the sudden shock to the drivetrain that once plagued early systems. We’re experimenting with direct-port injection for even finer atomization and distribution, and our custom solenoid designs are now capable of handling higher flow rates with exceptional reliability. The key is controlled aggression, ensuring maximum gains without compromising engine longevity. Imagine pulling away from a corner and, just as the revs climb, a controlled burst of nitrous slingshots you forward. It’s intoxicating.

Turbochargers: The Symphony of Spool
Turbocharging has truly come into its own in the motorcycle world. What was once the domain of drag bikes and custom builds is now a more accessible, albeit still technically demanding, path to incredible power. The principle remains the same: exhaust gases spin a turbine, which in turn drives a compressor, forcing more air into the engine. The result? A significant boost in horsepower and torque across a broad RPM range.

Our focus at HardRider is on intelligent turbo integration. We’re developing incredibly compact, ceramic ball-bearing turbos that offer minimal lag and maximum efficiency. Materials science has played a huge role here, allowing for lighter, stronger compressor and turbine wheels. But the real magic happens in the electronic control. Modern engine management systems (ECUs) are so sophisticated that they can dynamically adjust fuel, timing, and boost pressure based on a multitude of sensor inputs. We’re seeing variable geometry turbos making their way into the bike world, offering even broader powerbands and virtually eliminating lag. Our custom exhaust manifolds are designed for optimal gas flow, reducing backpressure and ensuring the turbo spools up with lightning speed. The feeling of a perfectly tuned turbo kicking in, building power with a controlled, relentless surge, is truly addictive. It’s like an invisible hand pushing you harder and harder as the RPMs climb.

Superchargers: Instant, Linear Domination
Where turbos use exhaust gases, superchargers are belt-driven directly by the engine, providing instant boost from idle. This mechanical connection eliminates lag entirely, delivering a supremely linear and predictable power delivery that many riders prefer, especially for street and track riding where immediate response is paramount.

HardRider’s supercharger kits are designed for seamless integration and maximum efficiency. We’re primarily focused on centrifugal superchargers for their compact size and high efficiency at higher RPMs, though positive displacement blowers have their place in certain applications. The biggest challenge, and where we excel, is in packaging these units elegantly into often-cramped motorcycle frames without compromising ergonomics or cooling. Our custom billet intake manifolds ensure optimal airflow, and our intercooler designs are constantly evolving to keep charge air temperatures as low as possible – crucial for preventing detonation and maximizing power. The whine of a supercharger, building in intensity with the engine’s RPM, is a unique soundtrack to effortless, massive power. It’s like having an always-on torrent of horsepower at your command, every single time you twist the throttle.

Competitive Racing? Big Power - More Will Be Needed.
Of course, none of this power means a thing without the supporting cast. HardRider MotoWerks is equally dedicated to developing and refining the components that allow these immense power gains to be used safely and reliably:
Engine Internals: For significant boost levels, stock internals often won’t cut it. We offer forged pistons, stronger connecting rods, and reinforced crankshafts designed to withstand the increased pressures and temperatures.
Fuel Systems: More air demands more fuel. Our high-flow fuel pumps, larger injectors, and adjustable fuel pressure regulators ensure the engine is always fed precisely what it needs.
Clutch and Drivetrain: The extra torque will make short work of a stock clutch. We provide multi-plate racing clutches and heavy-duty chains/sprockets to transfer all that newfound power to the rear wheel without slippage or failure.
Cooling Systems: Forced induction generates heat. Our oversized radiators, auxiliary oil coolers, and advanced coolant formulations are critical for maintaining optimal engine temperatures.
ECU Tuning and Electronics: This is where the magic truly happens. Dyna tuning experts develop custom maps for every kit, optimizing fuel delivery, ignition timing, and boost control for maximum performance and reliability. We leverage standalone ECUs and piggyback modules to achieve granular control over every aspect of the engine’s operation.

The Future is Now (and Beyond)
What’s next for HardRider MotoWerks? We’re continually pushing the envelope. We’re exploring integrated turbo-electric hybrid systems that could offer instant electric torque fill at low RPMs before the turbo spools, essentially eliminating lag. Variable compression ratios, advanced ceramic coatings for even greater thermal efficiency, and even more sophisticated active aerodynamic solutions are on our drawing boards. The lines between internal combustion and electric are blurring, and we’re excited to be at the forefront of this evolution, ensuring that the thrill of two-wheeled performance only gets more intense.

So, whether you’re chasing that elusive quarter-mile record, carving canyons with unparalleled thrust, or simply want to know that your machine possesses a deep, potent well of power, HardRider MotoWerks is here to make your performance dreams a roaring reality. The future of motorcycles isn’t just fast; it’s exhilaratingly, unequivocally HardRider. Keep those throttles pinned, my friends!
