A collection of precisely calibrated fuel metering components designed for carburetors manufactured by Keihin. These kits allow for the fine-tuning of an engine’s air-fuel mixture across various operating conditions. For example, a rider experiencing lean running conditions at high RPM might utilize a larger-sized component from such a kit to enrich the mixture and improve performance.
The utilization of these kits is essential for optimizing engine performance following modifications such as exhaust system upgrades or air filter changes. Correctly adjusting the fuel delivery through careful selection and installation of the appropriate sized component from such a kit can result in improved throttle response, increased power output, and enhanced fuel efficiency. Historically, such kits were developed to address the limitations of fixed jetting configurations in carburetors, allowing tuners to adapt to specific engine builds and environmental conditions.
