Thought I would share a little experience I had with my 04 pitbull.
I bought the bike used in February with 4,300 miles on it. I've put 500 miles on it since. About 100 miles ago, I started hearing what sounded like a dry squeal noise coming from the primary. Every time I would take off from a stop, or get on it a little, I would hear it. Never heard it any other time.
I removed the outer primary cover and inspected inside without removing anything else, and everything looked good. I put it back together and while I was at it switched to Amsoil synthetic. That quieted things down, but the squeal was still there.
I took it into the shop last week and told them I thought it was my inner primary bearing going out. They pulled it apart and found the compensator nut had come loose. Since it was apart, I had all the seals and bearings replaced. It runs perfect now.
I was talking to another local Big Dog owner who has a 04 Chopper and he told me he had the same thing happen.
Anyway, happy ending catching it before it something really went sideways.
Anybody else have this happen?
