I do not know how to answer your question :?: . Everything you said above is the problems with the stock system and just a little more and the kit fixes most of them :idea: . Under load you lose more power with the stock set up then with a well tuned kit. Going through sand washes the machine has more slippage through the belt system with the stock system then with a modified system. A good clutch kit will give you a much better seat of the pants feel then the stock system. You will get up in the power band faster and get there faster and in some cases even more top end. Pulling a heavy trailer down the side of a mountain is a big difference because of the braking improvements. Ask anybody that started with the stock system and then upgraded and they will say it is a night and day difference and the performance. Your belts will last longer and not slip as much on the sheaves. The stock system is not that efficient and never has been. I know this first hand because i have done quite a few of them and have seen the before and after effects. If you can give me a clearer question i can try to answer your question a little better :idea:  . But on the other hand since you do not haul any loads and run through sand washes or plow snow or rock crawl you may be just fine with what you have but as you get more seat time you will see what all the shortcomings are with the drives like i have seen :idea: .

The kit from dirty dawg is supposed to make a major night and day difference and eliminate most of or all the problems you are talking about. They are the most expensive but said to be worth every penny. I did a few on a some friends Razors and Rangers about a year or so ago and they were very impressed with them. Mine has the one from EpI and it made mine allot better and I now put more power to the ground and it was really noticeable in the sand washes and i don't smell the belt as nearly much anymore when pulling the trailer like the one you see on my post and i pull it loaded up hills and down hills loaded like you see it. I am going to talk to Dale over there at Dirty Dawg if the money starts flowing again and still do the upgrade because his kit is supposed to be twice as good as the one I am Running now from EPI. I always said that this should always be the first modification on a Polaris because the factory stock setup has its major issues. You should call him up and do one before your moab trip but make sure you give him all your information so he can tune it in for you and your uses :idea: .

Well this can get to be a very involved answer because from model to model year, and from the standard RZR to the RZR-s it is all about what they did to tune the clutch. Standard rzrs from 9/30/08 and before had the good secondary clutch system and 10/01/08 and after used the basic same cheap crappy one that is used on the Ranger Xp. The Rzr-s was never effected with this change. The difference between the standard RZR and the RZR-s primary clutch is tuning and EBS and by removing the limiter on the RZR-s models. On the 2010 models they removed the limiter and the sheaves are still about the same. there are a few part number changes but none of which would blow a belt. Like i stated earlier in the thread, belt failure is normally related to alignment problems, Broken engine or transmission mounts or a defective belt. I personally would not just take the limiter off unless i was going to do a full clutch kit and check the alignment anyways but that is me. As for every one person that has had the belt issue there are 20 that don't. There are much better belts out there like the ones from dayco that are much stronger then the stock belts. Like with all modifications there will always be a risk that a modification that is done to one machine may not work as well on a same model but a different machine. Until you try it you will never know what the outcome will be. As for doing any modifications it should only be done if you are mechanically inclined and if that is not the case i would deal with a guy like dale at dirty dawg performance and have him set it up for you.....
