Ok, the bike is an '02 WR 426, but I have an IMS tank (and YZ seat), but still running the stock WR shrouds. I want to put on a new set of high quality OEM style graphics to protect the plastics. What should I order? YZ or WR? I know the dimensions on the IMS tank are closer to YZ spec (it fits a YZ seat), so that makes me think YZ graphics. But, are the shrouds different between the WR and YZ on the '02? Thanks in advance.
