Got a Hinson basket for my 00' 426 and in thier instructions they cautioned aggainst using kevlar friction plates. I did call them and they suggested not to use them but to use O.E.M. plates and to use Vavoline 10-40 motor oil in the bike as well. This kinda through me for a loop ( The oil, not the bike!) I've been using Mobile 1 red cap oil without any problems. Thanks for your help.
