With the proper revs back, overall performance was restored with proper acceleration and back-shifting under load. We installed the Dalton XP1K clutch kit per instructions and were very impressed with initial testing.
Each weight is drilled and tapped almost all the way through, and the kit has a selection of M5 set screws (long and short) and three sets of rivets of varying weights, so overall weight can be fine-tuned without removing the primary every time you want to run a different tire or change altitude. The DUV P10XP/P10XP4 kit includes Dalton’s patented Quick Adjust flyweight system, which is really clever. Second, the Dalton kit has new primary-clutch weights that allow fine-tuning without disassembly. Using the shallow ramp, we gained rpm to put us back at the 8200–8600 rpm optimum. First, the helix has two ramps machined into it, and the more shallow ramp shifts slower and allows more rpm. This is a very impressive kit, because it allows tuning for tire size and weight in two ways. Dale sent UTV Action a Dalton clutch kit for the XP1K. Removing weight adds rpm.Ī call to Dale at Dalton Industries of Nova Scotia, Canada, set us on the path to more rpm. Dalton recommends keeping a log of what weights you’re running and marking each flyweight as you make changes to avoid confusion. The Dalton XP1K kit even includes a long T-handle Allen for adding or removing the M5 set screws. With the 32-inch GBCs and Fuels, rpm was off by 400 rpm. The 30-inch Kanati Mongrels we took off of the XP1K weigh 52.4 pounds each, but part of that weight difference is eight-ply versus 10-ply. The GBC/OMF combo weighs 56.8 pounds each, while the Fuels weigh 60.6 pounds each. Both are 10-ply tires, so we put them on bathroom scales. Next, we mounted a set of 32x10R15 GBC Terra Masters (March, 2018) on OMF 15-inch beadlock wheels. Our long-term 2015 Polaris RZR XP 1000 has had many sets of 30-inch tires, and the first set of 32s were Fuel Grippers (February 2018) on 15-inch Fuel Anza beadlock rims. We bombed Last Chance Canyon at speed with these Fuel 32x10R15 Grippers with no worries, rips or flats. A car designed for 29-inch tires will not build revs properly with 32s, so an aftermarket CVT kit will be necessary for the UTV to run right.Īre 32-inch tires for you? As they say, “The bigger the tire, the smaller the hole.” Ride quality is greatly improved with 32-inch tires, and you can run lower tire pressures without worrying about pinch flats. More weight and greater leverage on the CVs, axles, bearings, diff gears and the driveline in general are concerns, but the greatest problem to overcome is CVT tuning. GBC’s 30x10R14 Kanati Mongrels on Method beadlock rims weigh 52.4 pounds each.īesides extra cost, they also add weight. We mounted a set of GBC 32x10R15 Kanati Terra Masters on OMF beadlock wheels, and they weigh 56.8 pounds each. We love the new Kanati Terra Masters at 13 psi. More sidewall means more flex for a better ride, especially if you run lower pressures. More sidewall provides more cushion for a better ride quality, although the trend is also moving towards more 15-inch rims, which reduces sidewall slightly.
They also increase ride quality, as they roll over rocks and roots more easily, and increase traction by providing a larger contact patch. Besides lightening our wallets, what do 32-inch tires do for us? First off, they increase ground clearance, which reduces damage to suspension components and skid-plate wear and tear.
