Product Overview
Jetting changes are commonly needed after an exhaust, intake, airbox, elevation, or engine modification—not simply because the ATV is hard to start. This kit provides tuning pieces for compatible Keihin carburetors so the air/fuel mixture can be matched to the machine's actual setup.
Jet selection is not one-size-fits-all. Confirm carburetor type, modifications, altitude, temperature, and plug readings, then follow a proven tuning sequence.

Frequently Asked Questions
Q: Will a jet kit repair a dirty carburetor? A: No. Clean and mechanically repair the carburetor first.

Q: Which jet should I install? A: That depends on modifications, altitude, temperature, and the carburetor setup; use a tuning guide for the machine.
Q: Can incorrect jetting damage the engine? A: Yes. An excessively lean mixture can raise temperature, so tune carefully.
