Mikuni 633 Series Needle Jet

Description

This jet is identified by the numbers 633 being stamped on it but you may also find that there are other needle jets that though having a different series number stamped on them, are in fact identical to the 633 and thus interchangeable. The 633 series are used in some original equipment TMX carburetors found on production bikes.

The lower the letter and number indicates the leaner the jet. Example N-6 is leaner than N-8. These are in 0.01mm increments and the 1/2 size 5’s are in a 0.005mm increments. Only the shown sizes are available.

For rectifying running issues with 2000 model CR Honda’s we also have a range of Jet Needles and a leaner throttle Valve.
