I am trying to learn about my team clutch. My question is, I see two sets of numbers on my helix, I am guessing this means the helix is like two helixes in one, but not sure. the numbers are 70-48-46 and 74-48-46. My spring is red with a little bit of dark blue, is this a good set up for any thing?

Yes that setup should work fine. What do you have for weights? Won't be able to go up in weights as much with the 48 finish angle.Probably just use the 66 gm weights and see where your rpms are at and go from there. The angle on the helix is basically how you described it. You can run either angle not much difference between the 2 the first # is where the helix starts at.

I am going to put this clutch on an 02 xc 800, what should I run for a primary spring an weights?

I'd just use the stock weights and see where you rpms are at. Then if you need to drop them add weight. Primary spring go with 150/310 or 165/310. 165 will give you higher engagement.
