i just got a set of triple PSI pipes for my xlt and i need some help with the clutching. right now it will hit about 8400-8500 rpms with the clutch setup it currently has. i have heard that running the xlt engine between 8400-8700 will hurt the engine and that 9100-9200 is the sweet spot for it. it has the blue primary spring, but i dont know what the weights or the secondary spring or helix is. i ride alot of trails and drag race my friends sometimes, and the most i ever saw when it was stock was 75 in a field. what would be a good setup for me and this sled?

is the clutching all stock? the secondary will just slide off after you unbolt it, if it isnt stock then it may have markings on it, if u cant see the marks on the weights then you can take it off and compress it by having a buddy stand on it. but if its all stock go to http://parts.polarisind.com/Browse/Browse.asp and look it up.

I've got PSI pipes on my sled. Its been a long time since I have looked at the PSI specs but I think you should be at 9,200 rpm. As for going over 8,700 I never had a problem when it was a stock engine pulling 9,200 rpm. I've since ported it and welded the crank. Now it turns 10,000 rpm.

I wish I still had the specs that PSI gave me with my pipes. But I believe you should have 10m Red weights with a blue spring. I dont remember if it was a Polaris or EPI spring.
