This part being universal, it may require adaptations
KEIHIN 110 main jet designed for fine-tuning the fuel mixture. This replacement part from KEIHIN is aimed at motorcyclists who want to master the richness at wide open throttle without ambiguity.
The main jet regulates the amount of fuel admitted into the wide-open circuit of the carburetor. A size 110 corresponds to a standardized orifice diameter: replacing or modifying this jet allows for adjusting the richness of the air/fuel mixture when changing the exhaust, air filter, or after needle adjustment. It is a precision component: when chosen correctly, it helps stabilize engine response during acceleration and prevents a mixture that is too lean or too rich at high RPM.
Before any intervention, check compatibility with your model and the type of carburetor. Installation often requires removing the carburetor bowl and using appropriate tools to avoid damaging the orifice. If in doubt, consult your tuner or motorcycle shop for reliable adjustment.
