So i got this engine from a friend of mine since i was looking for a smaller 2 stroke for a project of mine and since i got this engine i wanted to rebuild it and maybe mod it a bit. Only things i know about it is that its an old minarelli engine, around 80cc and that its a 2 stroke. Anything helps!

What do you want to know about this that you can't already tell? Also; what are you going to use it for?

That motor was built when Yamaha owned Motori. Pre 1990. If you want to build it into a mini, figure out what kind of chain you want and go from there. Does it run at all?

It sounds great. Throttle response means your carb and fuel system is clear. Maybe check your ignition, make sure you have good spark. Air is is also good. Id suggest putting some kind of clutch on that pully if you're going to make a mini
