Default Re: Here are some facts...

I can tell there are different engine makers by the castings....and something silly like some factories use 8mmX1.00mm head studs others use 8mmX1.25 studs.

Allow me to ask this:

Are there more than 2 carb factories? I've only seem 2 close twins.

ALL The supposed 80 cc engine that really is 67cc or whatever - do they actually have different bore and stroke?
