This part being universal, it may require adaptations
Replace or adjust your main jet with this sharp KEIHIN model for carburetor tuning. The KEIHIN 175 main jet allows you to fine-tune the air/fuel mixture richness at higher and mid-range RPMs, providing better carburation suited for engine modifications or variations in altitude and temperature. Ideal for riders looking to refine throttle response and smoothness at full throttle, without rough adjustments.
This jet installs in the carburetor body (a process that involves disassembling the float bowl). For precise tuning, conduct road tests or use a dynamometer and check the spark plug color to validate the richness. If you are unsure about the procedure, consult a workshop or a carburetor specialist to avoid an inappropriate adjustment that could harm the engine.
Designed for demanding users, this KEIHIN jet offers a simple and reliable solution for adjusting carburation. Be sure to keep the old part and note the initial settings before any modifications.
