Hello, I am new to the forum and I need your help diagnosing an issue I have with my Uly. The bike is a 2008 Uly with 55k miles on it I bought used a year ago. Only about 3k miles are mine. Recent work done to the bike is new front and rear brake pads and rotors, new fork seals, new starter, new battery, new voltage regulator. About a two weeks after the starter repair, the motorcycle would make a loud shudder on hard throttle. The shudder has gotten worse. Now on throttle on and throttle off, the bike makes a loud clunk and will then shudder. It sounds like a something is catching and releasing. The whole motorcycle shakes. The slip/stick shudder goes away after a few moments of steady throttle. Also, the bike feels like it has a slight side to side wobble. This noise only occurs under load. I can rev it in neutral and everything sounds great. No problems until I try to put load on it. I opened up the primary. No obviously broken pieces. primary chain looks fine. sprocket looks good. Sprocket nuts seems tight. Primary oil is nearly black though with some foam on clutch cover. I didn't have the tooling to open up the clutch or pull the front sprocket. Any ideas? | ||

Have you checked your engine mounts and your headers to heads bolts? | ||

I think I found the culprit. Your post got me checking the chassis components. While I was looking at my rear isolator, I noticed metal flakes on the rear axle. I took the rear tire off and the right rear wheel bearing came out in three pieces. The outer race is still in the wheel, the inner race just fell out along with the dust covers. No sign of the ball bearings. There is massive gouging on the wheel spacer. I can't tell yet if there is damage to the wheel itself. I will have my local race shop fit new bearings in a few days. | ||

Well, that would do it! Good thing you found it, that could have gone really badly. |
