Changed oil.. Went riding with the guys. Was told that oil was leaking out my exhaust.. Checked it out. Went to start my bike the engine started to squeel...very loud. So went and got the trailer. Pushed the bike on and just pushing it.. Loud squeel.. Got it home put it on the stand.. If i rotate the rear tire it seams lower end.. Removed clutch cover. Basket looks good..just dreading spliting the case.. The noise is interment when pushing but when u start the bike....wow LOUD.. Any ideas..
