   just bought what I think is a 50cc malossi kit but it looks quite big for a 50 can a 50cc piston have a diameter bigger then 40mm?

   Very much doubt it. Sounds like you may have the 70cc which are generally 47mm.

   50cc pistons range from 38mm to 41mm in general, depends on the length of the stroke to calculate displacement.
