[QUOTE="69ST, post: 171463, member: 5"] The bore-up kit is a logical choice. I'd retain the stock cylinder, it should have enough material to overbore (someday)...cast iron can withstand a lot abuse. You should be able to carefully sand & polish the scarring out of the combustion chamber, with very little impact on total volume, especially with a 52mm piston. One thing that I'd check, closely, is the crankshaft assembly. The rod or/and crankshaft may have been bent. I'd also be looking for excessive clearance (radial & sideplay) at the big end of the rod.
