All the advantages of a flatslide pumper carburetor at a much friendlier price than a Keihin FCR.

Our complete genuine Mikuni TM40 pumper carburetor kit comes with alloy adapter rings bonded to the carburetor body for a firm reliable fit in the stock air boots. We also include a remote mounted choke knob, complete instructions along with a wide range of main jets and pilot jets for fine tuning or to accommodate bikes with extensive modifications.
