Going fast has never been so easy, say goodbye to hard starting, hesitations and flatspots.  These Mikuni carburetors are correctly sized and easily fitted to your Honda XR650R air box and intake manifold flange using the  silver anodized air-box adapter and engine outlet spigot adapter, both adapters are fitted prior to delivery when purchasing complete kits. The kit also comes with throttle cables and a 1/4 turn quick action throttle. There are jets provided that must be changed as well as spares for fine tuning. 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 have included what we have found to be a range of jets to allow you to tune to most variables. The TM40-6 comes with a cable choke whilst also in the kit is included the optional knob choke assembly.

You will instantly experience better throttle response, improved acceleration, increased horsepower and torque.  In a number of instances Dyno tests have shown improvements of up to and over 25%  when fitted to OEM carburetored engines.


If wishing to modify or use your existing Honda XR600, XR650 cables to suit the Mikuni TM40-6 or use a POD filter rather than the original air-box you can purchase the carburetor, tuner jet kit and or what ever other components you want individually by following the directions below.

On the main menu to the left of the page, hover over the carb listing for TM Carbs with Accel Pump and then select TM40-6 from the drop down list. When clicking on any individual size Mikuni carb from the drop down list it will put you into a page showing not only the Mikuni carb itself but also any items relevant to that carb, being Mikuni jets, Mikuni flanges, Mikuni carb tuner kits, Mikuni cables , Mikuni throttles, Mikuni air-cleaners and a range of Mikuni carb to OEM air box adaptors etc to also suit. This also makes alternate jet selection easy for you if you have your own spec as only the type jets for that particular carb are shown.
Click on the carb itself if wanting to view the full details and or to make your purchase. Then back arrow back in the carbs main page and go into the tuner kits, which show in the sales drop down list the jetting kits we have for confirmed suitable engines for that particular carb. Again thoroughly read the tuner kit description.

    If you have an XR650R with the original carb and like me are wondering why your brp is living up to it’s name, all i can say is buy one of these kits, you will not be disappointed. Started literally first kick after installing the TM40. Installation was a breeze and took no time at all. Fitted straight on with no alterations to the tank and the difference is outstanding. Runs and idles perfectly and the power is instant and without hesitation. Also doesn’t pour fuel onto the road like the original carb:) i ride my xr to work most days and this kit has made my bike so much better to ride in all aspects. It’s a different bike. Best upgrade you can do to an Xr650r hands down.
