Hi Everyone, so the time has come to rebuild my top end.. I have sourced the holy grail bearings but cant seem to find crank seals? has anyone got any idea where I might find them? I am in South Africa. one more thing are the mc 18 pgm 2 and mc 21 barrels the same or is the port timing different? I might be able to get a decent 21 barrel which a lot cheaper than nIcasil in sa. Thanks in advance Troy.
