So, I'm trying to find a WR400/426 in my price range, $2400 or so, here in Boise..but I'm not having much luck. What I can find in my price range however are a bunch of YZF400/426's. Would it be feasible or cost effective to convert the YZF to a WR? What am I looking at...lighting kit, flywheel, chainrings? Or, should I just get a WR to begin with?
