Ok so both engines have a stroke of 39mm, both are piston port, so A Puch top end should work on a Morini bottom end.
Should with some work...Such as cutting off the Puch cylinder skirt, or trimming it down so that it could slide into the Morini bottom end
I dont know about the studs, but I would safely assume that one could drill new stud holes in say a Puch cylinder to correct this?
and if you were going to run a kit you'd have to keep it smaller, say the 60cc's maybe an Athena or something, anyhow
Has anyone done this? Pro tips for me?
