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?
