WARNING: This carburetor kit will seriously wake up your machine!

Do you want even more throttle response?  Then upgrade your Norton kit with the Mikuni TM flat-slide carburetor.  The Mikuni TM flat-slide carburetors deliver even more enhanced throttle response and power through their free flowing flat-slide design.  Air flows faster and smoother through the TM series due to the flat-slide design and the jet blocks which help create a smooth bore effect.  The higher velocity means stronger vacuum at the needle jet providing precise metering and better atomization.  Select the upgrade option now before adding to your cart. 


TM36-68 Pumper carburetor can also be substituted in this kit.  This will require an extra cable set, throttle assembly, and air filter which is provided with the upgrade option.  Please inquire with any questions.
