Do i want my mountain clutch setup to engage at a high rpm or a low one? Soooo confused here. any help would be greatly appreciated. Does 5000 rpm seem like the right engagement rpm for the mountains?

More weight on the toe of the weight = higher engagement or less weight on the heel of the weight will do the same thing. I assume you removed a rivet from the clutch? Try and weight your weights so you have more of the total weight to the heel. More weight on the end is better for drag racing...not so good in the mountains. Might be time to buy a new spring too. Any yammie dealer should have a high altitude recommended spring for your setup.
