I can't see it for carbon... The shorter piston skirt, which I assume may have been shortened by the owner (used kit btw...) is facing up. That should be intake right?
I done have the gasket kit for this, and the stock head hits with no gasket, so I dremilled out my old 1hp aluminum gasket to fit the 65cc.
How do you guys run the stock or high comp 50cc heads?
