I removed the top end yesterday, I can't help thinking that this is low hour bike, Mahle piston, the bore looks very usable, piston measures at 81.82, 81.92 is standard, not bad after 43 years! It was always my intention to split the cases to replace seals etc, but since the crusty rust on the barrel studs fell into the crankcases, it wasn't my decision anyway, the big end feels great, mains are smooth but I'll check them once I split the cases.
Have a look at that ring gap! I knew compression was down, but I didn't expect just over 4mm end gap.
I'll have a friend mic the barrel for taper etc and go from there.
