hello all,
i had these great bikes as a youth and never stopped riding bikes , the bikes got bigger and faster , i was clearing some parts and space out from my 54 bike + spares and found a few parts which i think will be fun.
most of the 550 engine is there , crank rebuilt , fresh bearings seals and rods OUCH.
where is a good source for pistons ?
i have seen the re pop ones on ebolabay but am wary of unknown makes , i emailed all the usual suspects wossner , wiseco , etc
any recommendations guys ?

Remember that there are distinctly different GT550 engines, early and late - plus some late ones had Nikasil plated bores and the pistons and rings are different on these. Changes were made year on year to some parts too.
Clutches are distinct, early and late Borg Warner types. Late engines have gearchange indicator too. Start with and engine number and we might be able to help - or look HERE (clicky linky) and find year/model etc.
THIS LINK (clicky) tells you lots of stuff too.
