KEIHIN Main Jet 100mm
Manufacturer reference: 1001-806-80-100

KEIHIN main jet designed for carburetion and engine tuning operations. A central element of the fuel circuit, this jet controls the amount of fuel admitted through the throttle at high RPM. Replacing or adjusting the main jet is part of the basic "carb" tuning to achieve a mixture suited to the operating conditions (altitude, temperature, exhaust, air filter...).

• Usage: intervention for adjusting the mixture on carburetors, optimizing throttle response, and monitoring fuel consumption at full load.
• Manufacturer Quality: KEIHIN manufacturing, compliant with the precision requirements expected for carburetion components.
• Reference: 1001-806-80-100 — commercial designation: KEIHIN Main Jet 100mm.

Installation tips: replace the jet when the engine is cold, clean the seat, and check for any deposits in the carburetor well. Screw in without forcing to avoid damaging the tools or the part. Gradually proceed with road tests and fine-tune the jet size based on the spark plug color and acceleration behavior.

Note: before placing an order, check compatibility with your carburetor and the need for specific tuning for your motorcycle. If in doubt, entrust the tuning to a carburetion professional.
