Ok, I have to buy a new piston in the morning, the one I'm replacing, due to being holed, is Mugello 198cc, 66mm, modified to work with reed valve (skirt cut and windows cut). Do I need to buy a Mugello one and have the work dne again or are there 66mm Pistons out there that already have the windows and skirt done? Any thought most appreciated as always

Not sure on size, I just replaced the original crank, GP, with a Mec Eur road/race crank. So it would be a standard size, whatever that isspeedy wrote:Not sure what length conrod your using, but Ben at AF has used the RB 20 piston in em, but that piston uses the 116mm rod,cheers,Speedy.
