Going fast has never been so easy. The number one performance carburettor flows 213 CFM, 17 CFM more than the TM40-6 and delivers around a 25% improvement in performance and power over stock carbs.

This carburetor can be adapted to a number of different applications where space allows.

In other applications where some modifications are required for fitting, any effort and time spent is soon forgotten once you experience the better throttle response, improved acceleration, increased power and torque. Mikuni’s smoothbore, flatslide with roller bearings, and accelerator pump technology delivers peak performance from idle to Wide Open Throttle.

The in carb jetting is suitable for twins with a 900cc and bigger engine capacity whilst just purchasing one size up and one size down in the main jets to be able to fine tune the top end would be an adequate starting point.
