I just finised rebuilding my motor on my 2004 1200 XLT and got every thing buttoned up. Went to fire it up and it starts making a bad whinning noies sounds like its coming from the driveshaft.

Has anyone ever had this problem.

I know there is some bearings down there, but it was never a problem before until first time i try to start after rebuild.

let me know any advice or simmilar experiences.

I'm going to pull the exhust off again and inspect closer tommorow.
