How did your rebuilding go...I was going to rebuild this one as they person I got it from cheap said it had low compression. Tested it and it seems ok. Cleaned carb as I thought maybe that was the problem. Did you have to have it bored? Wondering if I do rebuilt if I could get away with new rings.
new oversize piston kit, size +50
new con rod kits,
new bearings
new gasket for the head and water panel on the head
All parts from Taiwan
total cost around 300$
