i just did my 600 and my instuctions dont include 500 either, look at what they changed on 600 and start there, bump 1size on main, needle up.5(check your alt.) then you have two see how sled reacts and clutch from there, you want to bring up engagement with stiffer spring and check wot shift out rpms (to high) add rivit weight to primary. hope that helps
