MAIN JETS (Size same as Keihin 99101-357 Main Jet 16.5mm in length with a 6mm Round Head)

The main jet primarily affects fuel delivery at higher throttle openings and higher RPM. Having a range of main jet sizes allows you to properly tune for modifications and riding conditions.

PILOT JETS (Same size as Keihin N424-21 Pilot/Slow Jet)

The pilot jet primarily affects starting, idle, and low-throttle operation. Having multiple sizes allows you to fine-tune low-speed throttle response and idle performance.

Jetting requirements vary by engine, carburetor, elevation, temperature, exhaust, air filter, fuel, and other modifications. Proper jetting is important for both performance and engine protection.
