i found a crack in my xr 650r rear wheel. anyone know where to get a new hoop for a good price? how about a whole new set up for the rear? anyone run a warp 9 wheel? i was thinking of just buy a whole new rear for the dirt and then use the old one for the sand? would it be wise to weld the crack for a temp time. i was looking for a rear on ebay but was thinking of welding til i can find a replacement. thanks for the help.
