Description
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 XR400 using the silver anodized air-box adapter which is 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 the main jet circuit doing WOT tests. 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 special jets to allow you to tune to most variables using different fuels world wide.
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.
The TM36-68 with the sleeve fitted matches the outside diameter at the air-box end. It also duplicates your OEM carbs front to back length. The engine end outlet spigot on the TM36 is 42mm where the Honda XR400 engine flange socket is a couple of mm larger than the 42mm. As it runs a risk of future failure to properly make a reliable sleeve 1mm thick with a then correct depth locator groove in it, as rubber doesn’t compress it displaces thus relying on adequate depth locator ring grooves. We prefer you (as literally thousands of customers before you) to just simply crank the rubber flange down onto the carb. When doing this always check that you have enough adjustment in the clamp to tension adequately.
IF NOT WANTING TO PURCHASE THE KIT IN ITS ADVERTISED FORM PLEASE FOLLOW THE DIRECTIONS BELOW.
If wishing to modify your existing Honda XR400 cables to suit the mikuni TM36-68 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 TM36-68 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’re comfortable with making a purchase of the carb, tuner kit any or other associated components, order it on line or otherwise please call us to further discuss your needs on 0747712677.
