Description

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 the Honda XR250, this is a simple ready to bolt on kit.

These Mikuni carburetors are suitably sized and easily fitted to the later model Honda XR250 (inc. Baja with TPS disconnected) using the steal gas tank and CV carburetor where it matches the air box and intake manifold flange using the  silver anodized air-box adapter and stock engine outlet spigot size. If wanting to fit to the earlier plastic tank models using the mechanical slide carb or wanting to use an aftermarket air filter you have the option to purchase the kit without the air-box adapter or otherwise the adapter is fitted prior to delivery when purchasing complete kits.

Please note: 

XR250 with Plastic tank and mechanical slide carb stock measures 40mm OD at motor- 97 long- 47 at air-filter

XR250L  Steel tank and CV carb stock measures 40mm OD at motor- 103 long- 55 at air-box end

The kit also comes with throttle cables and a 1/4 turn quick action throttle as the Honda cables have a non-matching inner wire length. There are jets provided that may require fitting if your engine does run a little rich but usually its just bolt on and go. Climate, altitude and fuel density from different octane fuels all 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 an silver anodized air-box adapter fitted to the carb, a pair of cables and quick action throttle, a pilot and main jet for tuning.

IF NOT WANTING TO PURCHASE THE KIT IN ITS ADVERTISED FORM PLEASE FOLLOW THE DIRECTIONS BELOW.

    After looking around for a standard carburettor for our Xr250r we could not find a second hand and genuine Honda was rediculously over priced I contacted Tom from mukuni oz and with enormous amount of experience he recommended the Tm33 mukuni pumper carburettor. What a difference this carburettor has made. Gone is the flat spot when you first open the throttle. So much more responsive. Easy figment and the biggest bonus was the ability to be able to use the factory air cleaner with the extension supplied with this kit. I would recommend this kit to any XR250 owner who is having trouble with there factory carburettor or just for an instant lift in power.

    A customer requested to swap the original carburetor to a Mikuni TM33. He supplied the carburetor. On removing the original carby it was found that it had a TPS (Throttle Position Sensor). The TM33 does not have this. After reading many forums etc I reached out to http://www.mikunioz.com and they suggested to not connect the TPS connector. I had read that the bike at idle and low rpm would be compromised, but as per Tom from http://www.mikunioz.com, once fitted and I took it for a road test…. Idle was smooth, excellent throttle response, and was definitely more responsive than the original carby.
