Hi all,
I'm posting this on behalf of Steve Sullivan, a local club member, who would like to know the weight of an original piston (including gudgeon pin) for a 1929 550cc SV engine (86.4mm dia and lower crown height than a VB piston). Does anyone have this information please - or have a piston which they can weigh please?
He is getting bad vibration problems with a JP piston and so would like to try to match the original weight.
Thanks,
Graham
