Hi Todd, I watched your youtube videos and read some of the tech info on your website prior to posting this. I have a 2017 900s with a good amount of weight added to it. My bed box with tools and parts inside is easily 100lbs, I carry a full size spare tire (28x10x14 efx motoclaws on MSA m12 wheels), roof, door lowers, stereo system, soon to be light bars front and rear, 4500# winch, wildboar 10ga front bumper, and my 285lbs body. I ride with a passenger usually anywhere from 130-300lbs. I already put RT Pro heavy springs on it and that helped the machine ride much better (just to give an idea on how much weight I have to be managed). In reverse, the rzr is jumpy in low throttle, same with high gear, which is why most of the time I ride low gear unless I'm road riding where I know i can put the pedal down to keep rpm up enough to prevent the belt jerking. I know my belt has some cupping on it, it is the stock belt still and the machine has about 500+ miles on it. I ride hard pack and loose dirt, dirt and sand trails in lower michigan (i never go to the dunes), some mud (I stay out of the deep stuff), some rocky trails (not low speed low gear rock crawling, but I do hit black trails that are somewhat technical in navigating rocks and trees), and hill climbs. In your videos, you mention sometimes your HW belt can negate some issues of jerking, but my question to you is given everything above, do I need a clutch kit? If I did need a clutch kit, I was intrigued by the dalton clutch kits on your website and I would most definitely buy your belt. I just want to be an informed buyer. When I ride trails I am anywhere from 20-35mph (hatfield mccoy) to 35-50+(michigan, Houghton Lake area ORV trails). I appreciate any help you can send my way. I'd like to get all this done by the upcoming riding season.
