Help please.

I am looking for the best possible clutch kit to get more low end power out of my 2005 Yamaha Grizzly. Altitude is a factor as I will be riding anywhere from 2000 - 6500 feet. I checked EPI and they do not make an altitude product. Any info would be greatly appeciated.[[img]i/expressions/face-icon-small-confused.gif[/img]

 

im not the best mechanic but im not sure how alttitude would affect a spring and some weights...but thats just me, im not sure....i just bought a EPI big mudder kit and it should have some crazy torque on it cause it hurts the top end alot...sooo im guessing off the top down to the bottom..cant wait to get it on

 

Not sure what you checked under EPI but they do have an altitude kit for the Sport/Utility clutch. Maybe that's not the clutch you're looking for.
