I seem to have picked up a new vibration over the last few days. Its not noticable when the bike is first started, but seems to get worse as the bike gets hotter. Right now, I don't have a clue what's causing it. I had the right side muffler come loose a while back and I'm wondering if I might have gotten it shoved too far forward and bottomed out when I tightened the clamp. I need to change my back tire in the next week, so maybe when I do that, I'll just pull both mufflers and check it out. I don't seem to be hearing any odd noises to go along with the vibration, but something isn't right. Sure hope I didn't scissor the crank!!!!!!
