I bought a DDP clutch kits for my 2013 xp4. I took it out to sand mountain NV for Halloween and played around with it a bit and I have some questions. First off I ran it set up as sent to me and I was maxing out at 7500 rpm. The tip had the aluminum bolt in it so I left it alone. The middle weight was a green steel bolt. I replaced it with an aluminum one and then maxed out at 8000 rpm. Looking for a little more rpm I took out the bolt closest to the pivot and took off the two thick washers, and reinstalled the bolt. That resulted in 8400 rpm but it actually felt a little slower. I also killed two belts in a day so i put the two washers back in. So what am I doing right or wrong? What adjusts belt clamping vs rpm? Do the different weight positions do different things? Can you give me a crash course in weight selection and adjustments? Thanks!
