Jetting/Clutching

[newfattak]

I need some advice for my brothers sled, he has 2004 Warrior and we plan on going to the mountains sledding, What jet size will he require?
Right now the sled is bone stock, its jetted for 0-3000ft, we will be going to about 8500ft+, I think he runs 135 mains.
As for Clutching well I guess thats opening a can of worms, but what is the simpliest way to correct it for the hills, this is a once year event, so really don't want to go all out.
Thanks for any help you give.

128.8 or 127.5 mains, 3/4 turn out from seeted on fuel screw and remove rivits from weights. That should be the cheapest.

So these jets will not lean it out to much, if possible can you explain what you want to acheive regarding clutching? Correct me if I am wrong, but is it that you want to lighten up the clutch arms the higher in elevation you go? by doing this will it allow you to maintain the right revs for engagement and shift out? Kind of new to this so bare with me.
Also I have an 06 Attak, should I just do my weights as well?Thanks
