On my 2008 BMS Pathfinder 150. Had odd sound, possably bottom end slap. Wanted to check wrist pin clearance. So the ? is, putting it back in do I hone the cylinder or not? Piston has a little carbon on the top edge between piston and cylinder. AAAhhh, alas, to hone or not to hone, that is the question. Found the odd sound I think. Inti-roll back mechanism on valve train was damaged by previous owner. Was locking up rocker arms.
