so what is your overall impression? Does it have to rev up high and jumpy when you take off? Is it good for trail riding? Is the overall ride louder due to running at higher RPM's?I have been running the epi clutch for about 6 months now. Definitely has better acceleration. I lost about 3 mph on the top end. Belt engagement on take off is around 2200-2300 rpm's. The sport utility and duner kit are the exact same kit, but they have different part numbers.
Sport Utilty kit 0-3000' Stock tires WE436993. EPI told me for the rzr4, the duner kit and sport utility kit are the same thing, but they have different part numbers. I bought mine used off a guy on this site. It had the right springs, but the weights were set up for running 27" or bigger tires. I called EPI and got the correct weights(most expensive part of the kit of course). He said I could use the heavier weights if I rode with 4 adults all the time.What is the part number you guys installed?
