so we finally got some snow and i took the ultra out for a test ride since i jsut bought it and havent tried it yet. it runs good and pulls nice for a stock machine, but it shifts out at over 9,000rpm. i have 10 AL weights in the clutch which are 53 grams. they are heavier than the stock 10's. the primary spring is a silver i believe, the secondary has a red spring and 36 helix. the belt is new. i want to know why it is over revving. thnx.
