I might have a test of it in one of my old MiniCycle magazines...

Do you have one jory230? Or did you ever have one?

yea i have one i need a piston for it though in order to get it running again. i was told it was bored out but it doesnt really look like it but i cant find the factory specs for the cylinder size.

I was thinking if you bought a repair manual it would have the bore spec in it.

I was just looking thru my old minicycle mags and found the test on the 1973 MC-1 90cc...It says it had a 1.850" bore... 2.04" stroke..

Do you know what size your bore is?
