KEIHIN Jet 65 — a simple and essential part for adjusting your carburetion. Designed by KEIHIN, this size 65 jet is aimed at motorcyclists and mechanics looking to fine-tune the air/fuel mixture on a carburetor equipped for this diameter. Manufacturer reference: 99101-393-0650.
The jet is the precision element that meters the amount of fuel sent into the main circuit of the carburetor. This model 65 allows for fine-tuning the richness to achieve clean carburetion, optimize throttle response, and facilitate adjustments in the workshop. Ideal for tuning operations after intake or exhaust modifications, or simply to correct a mixture that is too lean or too rich.
Before installation, check compatibility with your carburetor (jet size and type) and keep cold/hot adjustment operations for accurate diagnostics. Simple installation: replace the existing jet with this one using an appropriate screwdriver and follow the adjustment procedures recommended by your carburetor manufacturer.
