Lex . . . Yes, very very dirty underneath. The engine is still in the bike. My "build" will be here and there while the bike still runs. Have to, until I get my 1st gen Toyota 4x4 on the road again. Brian . . . Love the "heat the engine" first ploy. I look forward to trying that. Or I'll air ratchet the buggars off. The one on the sump was so stripped by the PO that I couldn't resist grinding the hex back into it, albeit a mm or two smaller. Clutch adjust nut . . . I got mine loose with the air ratchet. I removed it and held in the bench vise first though. Maybe overkill, but it worked.
