What information are you looking for, displacement, age?

Mainly looking for displacement. Not sure if it is an 80cc or 100cc.

I know the 80cc had a 4 speed and the 100cc was a 5 speed, at least on the early-mid 70s Rupp cycles with Fuji engines. Not sure if that carried through for all years but may be a way to figure it out.
