Mikuni Carb TM40-6 40mm Flatslide Pumper Basic Kit Yamaha SR XT TT 500

  
Going fast has never been so easy, say goodbye to hard starting, hesitations and flatspots. This Mikuni TM40-6 carburetor is suited for high performance Yamaha 500cc SR, TT and XT models. This Mikuni TM40-6 Pumper carburetor fits as a direct replacement to the Yamaha SR, Yamaha TT and Yamaha XT inlet snorkel and with the fitment of the provided outlet mounting flange, which moves the carb slightly forward, enables it to properly clear the frame. Most Yamaha OEM Push/Pull throttle cables will fit this carb but Mikunioz does also offer an optional set of new throttle cables and a 1/4 turn quick action throttle. There is a hose tail on the carb for connection to vacuum operated fuel taps. The jets and pump nozzel required to make this carb operate on Yamaha 500cc singles have been fitted and there are 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 jets to allow you to tune to most variables using Australian fuels. At Mikunioz, for the last 30 years, we have been constantly checking and where necessary upgrading our jetting specs as fuel quality changes. Regular fuel in the USA is 85 octane or 91 in their premium brands which have numerous additives and blends added (basically smells and drys like wood varnish) which results in a totally different jetting spec and product performance.

This carb as supplied from the factory will never work on this bike and requires a total re-jet as supplied loose with your carb. 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.
