another interesting thing. when i was breaking my motor down on tuesday night (to put in a new crank - see yz400 stumper thread), i sacrifced a friction and a drive plate to make a hub holder. i had an extra friction, but it was late, and i had no choice but to use one of the drive plates from that bike. anyhow, when i went to get a new one, i found that the part number is superceded and the revised version is very wierd. it's not round on the outside. it actually has an odd shape cut into it on one side.

anybody know anything about that?
