The Jitsie main jet Race is developed specifically for use with the Jitsie main jet extension kit Race for Keihin PWK 28mm carburettors. Designed to deliver precise and consistent fuel metering, it ensures reliable fuelling when used in demanding trials and race conditions.

Unlike standard PWK main jets, the Race version features a flat-screwdriver slot on the jet head. This is essential when running the main jet extension system, as there is no clearance for a traditional T-bar tool once the extender is installed. The screwdriver slot allows quick and accurate installation and removal without compromising the compact design of the system.

Manufactured to tight tolerances from high-quality brass, the Jitsie main jet Race provides accurate fuel flow and long-term durability. Available in multiple sizes, it allows riders and tuners to fine-tune fuelling to suit riding conditions, altitude and engine setup.
