while installing my treats 70cc version 2 kit i noticed that the air intake port is way narrower than the original stock 1.5 cylinder. the opening was the same size but it seemed to taper off into a sort of triangle. Has anyone found a need to dremel out the port on these kits upon instalation? i was also wondering if it was possible/advisable to run the 50cc high comp head with the 70cc cylinder and piston.
thanks for all the help-Dave
