OK, I've tried the search function for the last 30 min and can't find an answer. I just put a new DID 520 VM X ring chain on my 04 WR 450. The rear wheel turns, but not as freely as it used to. I read in the forum search that some bikes have clearance problems with this chain. Has anyone had this experience with the WR? I also read that you can use a shim on the front sprocket but that doesn't seem to be where I'm having a problem. It seems like it is rubbing at the chain guide. Any help would be appreciated.
