This part being universal, it may require adaptations
The KEIHIN main jet 70 is a replacement part designed for carburetor tuning and maintenance operations. Designed to intervene in fuel distribution, this size 70 jet allows for adjustment of the main flow during acceleration, a crucial point for controlled fueling on the road or off-road.
Ideal for motorcyclists who tinker with their fueling, this jet is used during tuning phases to adapt the air/fuel mixture to conditions (altitude, temperature, type of gasoline, or engine modifications). Replacing a worn jet or installing a different size is part of the basic adjustments to restore a responsive engine behavior. Simple installation with common tools: turn off the ignition, drain the bowl if necessary, and carefully remove the jet.
Before ordering, check compatibility with your carburetor and keep the original settings to be able to revert back. In case of doubt, entrust the verification or installation to a specialized mechanic to ensure safe fueling and reliable operation.
