[QUOTE="Bunya, post: 1191202, member: 77196"] I just made simple adapters to match a few of the case bolt holes for one of my pullers. This made splitting the cases easy. The rod and bearing are good. Unfortunately, so were the main bearings. The play on the L/S of the crank is due to a bad journal. It's about .001" undersize one way, then turn it 90 deg. and it jumps up to close to .003" (inline with the rod). The corresponding main bearing is nice and tight and spins smoothly. The ID of the bearing looks good. There are some strange patterns and slight discoloration on the crank journal, but it doesn't look like it spun. Not sure but I think it may have been manufactured undersize and over time worn at the bottom of the stroke. In any event, it's trashed and has to be replaced. No, I didn't talk to Eric about the cylinder. He's really busy with moving so I didn't want to pester him unless I was going to send it his way. Now with the discovery of the bad crank, I'm even less sure of what to do. There's a complete motor on fleabay off a supposedly low hour bike for $500. The clutch cover doesn't look too badly worn and the shots thru the intake and exhaust look OK. But the bike I have now looked OK thru the exhaust, didn't rattle, and had decent compression (195), and it's wasted. This just sucks- [/QUOTE]
