KEIHIN Jet - Manufacturer Ref: 99101-393-0720
An essential adjustment part for Keihin carburetors, this jet allows for precise air-fuel mixture tuning. Designed for riders who modify their carburation (exhaust change, air filter, altitude, or engine preparation), it offers the ability to refine engine behavior at low and mid-range RPMs by adjusting the mixture richness.
Practical tips: replace the jet with the carburetor clean and closed, note the original size before disassembly, and proceed step by step during road tests to validate the new setting. Also check spark plugs and air filter for a complete diagnosis. Do not hesitate to consult a specialist if uncertain about the necessary diameter.
This product is intended for engines equipped with compatible Keihin carburetors. No reckless technical modifications: use suitable parts and follow the motorcycle manufacturer's recommendations.
