There are many items that actually need to be changed when you replace carburetors, throttle cables, Throttle Pedal Z Bar bushings, and etc. They are not cheap if you go with my parts. That is because I do not sell the cheap overseas garbage.

  • We installed the cam shaft bearings with my special tool. I just love that adapter. It puts those bearings right dead nuts on. When you put in the cam and it just spins by hand there is no better experience.
