I changed my tire the other night and to my horror the chain tension bolt on the sprocket side of the swingarm snapped off inside. I don't know how it became so hard to turn as I have never completely removed this bolt cuz there is no need to when changing the tire, so there is no way it would have become cross threaded. I know I will have to drill to remove this mess. Does anyone have any suggestions as of what to do after I drill it out. I will have to drill out @ least a 1/2 inch hole to remove the mess I made rigging it to work for the next day as I had a race. It held but I don't think it will hold for very long. I want to fix it the right way. I need feed back!
