So, I'm getting to to a point where I may be riding this bike after I got a bunch of bugs out. The muffler, which I presently have off the bike sounds like it's got a ton of rocks inside of it rattling around. Is there a way to fix this or have the baffles just fallen apart inside? Also, I see where people restore their bikes to almost new...I understand repainting and such but finding new parts is almost impossible anymore...how do you guys do it??
