So I picked up my completely used 2003 YZ125 the other day and it worked like a charm. Took off the wheel to replace the tube, put the wheel back on and now I can't get the bike to roll when it's off I know it's neutral because it rolls like an inch back and forth and then the wheel locks up. Tried loosening the chain but it didn't work. After that I completely lost my mind in trying to figure out what it is...wondering if you guys can help??? Thank you!
