Frequently Asked Questions
The main jet controls fuel flow at mid-range to full throttle operation. A larger number (like 100) means more fuel flow, while smaller numbers restrict fuel.
Signs of incorrect jetting include: rich running (black smoke, fouled plugs, poor fuel economy) or lean running (hesitation, popping on deceleration, overheating). Dyno testing or experienced tuning is recommended.
The 100 size is a common stock or mild performance size for FVM carburetors. Verify your original jet size to determine if this is an upgrade.
FVM11 and FVM22 carburetors use the same jet specifications. However, not all Mikuni models are compatible—verify your carburetor model before purchasing.
Yes. Performance modifications (intake, exhaust, porting) typically require rejetting for optimal performance and reliability.
