There's a lot of guys here that can help you , but...
You'll need to tell them more. Like what alt. you will be at and your gear ratio. and what you ride like. Are you a highmarker, boondocker, trail rider
[ gad for bid ] ?
With a stock 900 at 6 to 9000' '04 clutch '03 are different, 19 top and 34 bottom, I think I ran 64 gram weights in primary and 51 deg helix with a sno-pro green secondary spring. Another secondary might be a 49 deg. with red/ white spring. This set up was good for highmarking and quick shift from hard to soft powder. Good luck.
