I have a 2013 rzr xp4 900 with polaris stage II kit. I bought a used dirty dawg clutch kit. I ride in desert areas like ocotillo wells ca and Johnson valley ca. I usually have 4 people in the machine. I have mongrel 30" tires on raceline beadlocks. I am trying to set up the weights on my clutch. I'm only getting 7500 rpm and 60 mph top speed.
