Designed to regulate the fuel-air mixture in the carburetor, these screws allow you to fine-tune the engine's performance. Popular ATV brands like Honda, Yamaha, Polaris, Kawasaki, and Suzuki utilise fuel mixture screws to provide riders with precise control over their off-road vehicles. Getting the most out of your ATV or dirt bike is important and proper carburetor adjustment is a great place to start. Adjustment screws play a vital role in achieving optimal air-fuel ratios for smooth idling, responsive throttle, and improved horsepower out of a simple ATV carburetor tune. Keihin, Mikuni, and FCR carburetors often feature adjustable idle mixture screws that can be accessed with a screwdriver. CNC-machined from high-quality materials, aftermarket options like the Keihin FCR air-fuel mixture screw or the FCR carb screw offer enhanced durability and precise adjustments.
By turning the pilot screw, you can change the entire feel of power delivery out of your 2 or 4-stroke dirt bike and all-terrain vehicle. We also stock a selection of motorcycle ATV and UTV carby repair kits to refurbish your air/fuel management system and find the correct idle speed with new pilot jet options. Full videos are available to teach new riders how to alter the engine performance of moto vehicles without damaging or risking the engines' safe operating temperatures.
