Wow, what can I do now. I was riding on the Big Bear Trail Riders Big Bear Run last weekend on the hard course. After going through one of many rock gardens, noticed that my chain guide had been ripped off right where it attached at the swing arm. Do any of you smart guy's know any good tricks on how to get it fixed ? Also, will a 450R or a 250R or X swing arm fit the same on a 2005 450X ?
