Thanks Brett. I read with great interest many of your posts in this thread, particularly those where you took your engine apart for fun and replaced parts trying to track down your rattle noise. I'm not so concerned about the noises now, particularly as they do quiet down when the engine gets hot. My other bike is a Ducati Scrambler which is also a noisy-as-heck aircooled design. Even when running right they tend to sound like a box of rocks. As for PO maintenance, there wasn't any except for him installing a brand new battery for me, and I did pull the side cover to double check his work which looks fine. I was the first one to do anything to bike, and I definitely drained the oil from the right bolt. I haven't had a chance to try and restart the bike since my last ride to see if I'm still having starting problems, but I think I'll put some fuel system cleaner in the tank too and some more fresh gas. Will report back on how it starts.
