*We recommend purchasing a high volume oil pump kit 

Installation Note: It will save a lot of time and effort if the oil pump is installed while installing the bore kit (requires
cylinder removal).

Important Note: If using this carb kit on an ATC70 or TRX70, a normal Honda motorcycle throttle will be needed.  If you dont have one, we have one listed in this section (SKU TBW1051) that will work perfectly with the carburetor in the kit.
