Re: are these real or not!!! 58CC venture bicycle engines
I have a 45mm piston/barrel here.
It was a '70'cc motor, it had 40mm stroke in a 50cc case(6mm head studs).
I made it in to a 69cc but had to widen the barrel opening in the cases and redrill and tap cases for 8mm studs.
If any one is interested the piston/barrel and rings are in new condition, and probably hard to come by. I do not need these, I have offered them to Sub, who hasn't taken me up on them.
If Sub don't want them, I would be happy for them to go to a better home.
P.M. me if interested.
