just got a rapido 225 (69.49 ish),. it would proberbly run ok with a hone but i am going to get it rebored to 70mm to be on the safe side. what choises have i got with pistons, i was thinking suzuki rm 250 (1986) ?. cheers simon

avanti?

I have been having a correspondence with Ron about using one in my cast iron 225.

I hope he won't mind me quoting him the piston sizes are


"A" piston is 69.97mm "B" is 69.98mm & "C" is 69,99mm

Need to bore the cylinder to the size of the piston skirt plus 0.06mm for clearance on a cast iron

So an "A" would be bored to 70.03mm

My barrel measures somewhere between 69.45 - 69.49, so reckon I've got some scope here.

The only down side I see is if you eventually score the barrel our going to have to look for a different piston with OS available.
