Why Choose Keyster?

Keyster’s carburetor kits go beyond the basics, offering a wide variety of fuel control components not found in typical jet kits. Most aftermarket sets skip sizes in even increments, but Keyster carefully selects jet and needle sizes for precise air-fuel ratio tuning across low, mid, and high RPM ranges.

The AA Needle used in the needle valve is a standout feature — a high-performance rubber-tipped design that won an invention prize in Japan and offers far superior durability and sealing compared to OEM parts.

Applications:

Troubleshooting: Solve fuel delivery problems with comprehensive replacement parts

Tuning for Performance: Ideal when upgrading intake or exhaust systems — lets you match fuel delivery to airflow changes

Restoration: Restore smooth idle, throttle response, and top-end power with new, precision-matched parts

Note: Carburetors don’t generate power on their own. To get the most from this kit, adjustments should be made in conjunction with engine upgrades (air filter, exhaust, cam timing, etc.) to ensure proper fueling throughout the rev range.

Optimize your GSX-R1100's performance, restore its responsiveness, and tune it with precision — the Keyster way.
