Hello I have '06 WR450. Awhile ago I bought some (supermoto) 17" excell with haan hubs. The hubs are YZF not WR. I bought YZF spacers, took speedometer cable out. Front rotor hits in caliper if I tighten axle up properly. If I leave axle just shy of tight, rotor clears fine. I obviously can't ride it like that. Any ideas on what I need to make this setup work?
