No problem man. The clutch really acts as both I guess in a way. It relies on spring pressure, weights, cam angles, and centrifugal force. The front clutch (primary) relies more on centrifugal force, whereas the rear clutch (secondary) relies on torque and preload. It is very neat how it works, confusing yes, but neat and very tunable. You would be surprised how well those hop kits can wake a Polaris up, It is almost always very well money spent. The weights really act on the primary clutch to keep your rpm up in the desired powerband, which is important at higher elevations where the air is thinner and performance can suffer. Yes, I doubt you could drop 200 lbs off of one, but 100 pounds is not that hard to believe, I have seen it done. I have probably trimmed my Scrambler 400 down 50 or 60 lbs. just with a few aftermarket mods and not really trying to. You would be surprised how much the stock exhaust system weighs vs. an aftermarket. Glad I could help.

 

NCScrambler, I just got back from my mountain trip and since you gave me so much information before I thought I'd let you in on how it went. First, I got the main jet out of the Trail Boss and found it was actually a 118. Then I just decided to call the Polaris dealership in the mountain area and ask them what jet to use. They recommended a 112.5. I was lucky that my neighbor happened to have the right size so I stuck it in and it worked great. The bike ran just as well at 7600 feet as it does at 1100. Now the problem is I've got to put the 118 back in, what a pain in the butt. Thanks again for the help.
