I have a 1988 yamaha moto 4 200. The racers are stuck in my front hub.I tryed bashing out the old bearings with a socket and the sealed bearing busted and left the racers in. i also am having trouble getting the nut loose on the seconday clutch. and the oil plug is siezed on pretty good. tryed plyers, reverse tapping and blew the nut part right off the plug now there is a penny size hole through it.
