Re: Pretty little 49cc engine!
Have you actually measured the bore and stroke to confirm the CCs? Obviously someone has installed an aftermarket slant head. I don't know of any (I might be wrong here) that had 6mm stud holes so the head must flop around somewhat on the small studs. Will that present a problem seating the head on the gasket sealing surface or are you going to use a 49 head?
