5 Secrets To Boosting Your 1990 Suzuki Quads Performance

Ever wonder how to extract the maximum performance out of your 1990 Suzuki quad? From the lush trails of the countryside to the rugged tracks of motocross arenas, these classic machines still hold a special place in the hearts of riders. But getting the most out of your quad means understanding and applying some key upgrades and maintenance techniques. In this comprehensive guide, we'll delve into five secrets that will elevate the performance of your 1990 Suzuki quad, ensuring you get the speed, power, and handling you crave.

Secret 1: Optimize Your Engine

Enhancing Air Flow

One of the simplest yet most effective upgrades is improving your engine's air intake. Here's how:

• Install an aftermarket air filter: These filters allow more air to enter the engine, improving combustion efficiency.
• Port and polish your intake manifold: This process involves removing any burrs or rough edges that can restrict airflow.
• Check and clean your airbox: Ensure it's free from debris and that the airbox lid seals properly.

<p class="pro-note">🔧 Pro Tip: Always use a compatible air filter. An improper size can lead to decreased performance or engine damage.</p>

Fine-Tuning the Carburetor

Adjusting the carburetor can lead to significant performance gains:

• Jetting: Depending on altitude and modifications, you might need to adjust the jet sizes. Going too rich can cause fouling, while too lean might damage the engine.
• Adjust the air screw: This tweak can improve the idle and low-speed performance of your quad.

Optimizing Fuel Delivery

• Clean or replace fuel lines: Ensure they're free of cracks or leaks.
• Install a performance fuel pump: This can provide consistent pressure to your carburetor, enhancing fuel delivery.

Secret 2: Upgrading Suspension

Suspension Components Upgrade

A well-tuned suspension can make a significant difference in how your quad handles:

• Upgrade to performance shocks: More advanced shocks can offer better damping and increased ride height.
• Enhance front suspension: Consider upgrading the A-arms or using A-arm extenders for better ground clearance and travel.

Fine-Tuning Your Suspension

• Adjust preload: Set it according to your weight and riding style to improve control and comfort.
• Check and adjust rebound damping: This controls how fast the suspension rebounds after compression.

<p class="pro-note">🔧 Pro Tip: Regularly inspect your suspension bushings and bearings for signs of wear to maintain optimal performance.</p>

Secret 3: Enhancing Exhaust Systems

Unlock the Engine's Potential

Your quad's exhaust system can be a chokepoint:

• Install a performance exhaust: Opt for an aftermarket exhaust to improve flow and reduce back pressure.
• Customize your exhaust header: This can lead to optimal scavenging of exhaust gases for better power.

Tuning for Efficiency

• ECU Remap: After modifying your exhaust, an ECU remap can optimize the engine settings for the new setup.

Secret 4: Elevate Your Braking System

Braking System Upgrades

A better braking system is essential for safety and performance:

• Switch to stainless steel brake lines: These are less prone to expansion under heat, providing consistent braking performance.
• Upgrade your brake pads: Opt for high-performance pads that can handle the heat and provide better stopping power.

Brake Maintenance

• Regularly check brake fluid: Ensure it's at the right level and replace if it appears dirty.
• Bleed your brakes: This removes air from the system, improving responsiveness.

<p class="pro-note">🔧 Pro Tip: When bleeding brakes, ensure no air bubbles are trapped in the system by starting with the brake furthest from the master cylinder and working your way back.</p>

Secret 5: Revamp Your Tires and Wheels

Choosing the Right Tire

Tires are your quad's connection to the ground:

• Select tire size wisely: Larger tires can provide more clearance and grip, but might require a larger chain or sprocket.
• Pick the right tread pattern: Depending on your riding conditions, the right pattern can improve traction significantly.

Wheel Upgrades

• Upgrade rims: Stronger, lighter rims can not only look better but also handle rough terrains with ease.
• Consider beadlock rims: These can prevent tires from coming off in high-stress situations.

Tire Maintenance

• Regular rotation and balancing: This ensures even wear and optimal performance.
• Check tire pressure frequently: Proper pressure is key for handling and longevity.
