KEIHIN Main Jet 115 — Manufacturer reference: 99101-116-1150
This main jet from KEIHIN is designed for carburetion adjustment operations. Numbered 115, it allows modification of the amount of fuel injected into the main circuit of the carburetor to adapt the air/fuel mixture according to the engine's needs and operating conditions.
Designed for riders who work on carburetion, this jet integrates into standard adjustment procedures: road tests, spark plug readings, and step adjustments. It is used during altitude changes, exhaust configuration, or simply to correct a mixture that is too lean or too rich identified after diagnosis.
Installation and advice: replace the jet carefully, respecting the original settings as a starting point. After installation, conduct gradual tests and check the condition of the spark plug to fine-tune the adjustment. If in doubt, entrust the operation to a tuner or a specialized workshop to ensure reliable and safe carburetion.
