KEIHIN Main Jet 175
Calibrated replacement for fuel mixture, this KEIHIN main jet in size 175 allows for adjustment of the amount of fuel admitted from mid-range to full throttle. Designed for carburetor systems with interchangeable main jets, it is aimed at riders who adjust the mixture to achieve precise engine behavior according to road conditions, altitude, or intake and exhaust modifications.
Installation and adjustments: changing a main jet should be followed by checking the color of the spark plugs and a road or bench test to validate the mixture. Basic tools and a minimum of carburetion experience are required; if in doubt, entrust the operation to a professional. After installation, check the engine's consistency at all RPMs (idle, acceleration, full load).
