Going fast has never been so easy.  These carburetors have for a long time now been the popular carb of choice to fit to any 250cc or 300cc engine with allowable space, where chasing optimum increases in performance and power along with general smooth throttle response and ride-ability, with the nothing short of outstanding results when fitted to your Yamaha TTR250.

These Mikuni carburetors are compatible size matched for your Yamaha TTR250 air box boot and intake manifold rubber flange. For carb clearance the motorcycle’s top frame bracket requires a little material to be removed and the rear brake fluid reservoir slightly relocated by bending the mounting bracket. The kit comes with throttle cables and a 1/4 turn quick action throttle as the Yamaha cables come up short on overall length. There are jets provided where the pilot may require fitting if your engine does run a little rich and the new middle size main jet must be fitted with an additional one up and one down size supplied for perfect main jet size conformation when doing WOT test runs.

Climate, altitude and fuel density from different octane fuels all may have varying effects on final fine tuning as does cam, exhaust and cylinder head porting etc. For this reason we strongly suggest checking the tune as per the supplied instructions to maybe even get more performance than initially experienced.

This kit includes a TM33 -8012 carburetor, a pair of cables and quick action throttle, a pilot and three main jets for tuning.
