Minarelli Cylinder.

Bought me 2 of these cylinders. There cast iron and pretty heavy but have some potential. For $20.00 i couldn't pass them up. The bolt pattern is pretty close but the holes are smaller. So by the time i drill the holes out it will be perfecto. The bottom is square and smaller than the base of the chineese bottom end. So i will need to make a spacer plate / Mounting Plate. This thing has a 48 mm bore and 6 ports. it a true 80cc but. But it would take a 44 mm stroke and the ht is 39.5. so i got to throw the crank 2.5 mm extra. seems doable.

With a machine shop available to me anything is possible.
The minarelli v1 mopeds and V1L scooters run these engines.

I also have a Puch Reed Valve Cylinder to try to. But it was way more expensive. I'll post pics and vids after i get it together,
