Where a fitment line says "All", it means all years of the model named on that line, not all bikes.

## Description (the store's own text)

Mikuni 22mm round slide carburetor. Ready to run complete carb with jets, etc. This is a very good carb for 110cc-140cc pit bikes! Can be used with a stock KLX110 airbox, intake, and throttle cable. The intake could have better fitment, so we recommend utilizing the TBW1866 KLX110 stock head intake to maximize gains and fit best!

Lever up = Choke on
Lever down = Choke off

- 2 bolt flange type intake, 25mm ID on the intake side
