So Iv always wanted to build a hybrid cylinder engine out of our China girl bottom end and a jug and head from another bike or scooter. I remember reading years back about puch cylinders and heads being done and I saw a few videos on YouTube of them but never really dug in. I was looking up small piston bikes and came across a few that might work. Anyone else know of any possibilities for cylinder jugs and heads that are close with some modifications? I'd love to find a nickel sleeved cylinder that I could work with to make a killer hybrid engine =D
