On my way to Lakeland tonight the bike started to make a howling noise and got louder the farther i went. When i made it to my buddies place I put it on the centerstand and we noticed that the rim was very hot with more than usual gray dust and was making a slight grinding noise. I am suspecting that it might be the bearings in the final drive. Any thoughts? If it is, does anyone know where I can find a replacement one around here? Any help would be greatly appreciated!
