Well, here is the latest update on my evolving Jagged X experience. Joe at Fullerton Sand Sports did a great job in recommending a tire and wheel combination for the dunes. The rears are the STU 26" Blaster Pros, with 16 paddles and the 75/25 play cut, making them equal to having 12 full width paddles. The Pros are 1" wider, helping to give more bouyancy on the sand, and the 12" dia x 11" wide beadlock wheels also help in keeping the tire profile more flat. The fronts are 27" x 9" wide STU razor back smoothies. The net result is a larger diameter tire and a resulting "taller" gear ratio. Also, the wider wheels and tires provide about a 3-4" wider track, front and rear. As an added benefit, the fronts were about 12 lbs. lighter than the origional Bighorns, and the rears about 14 lbs. lighter.
This combination was awesome on both the early morning wet sand, as well as the late afternoon dry and deep sand inland from the ocean. I really loved the new combination. I didn't seem to loose anything while making sliding power turns in AWD, and the engine rpms were turning lower while maintaining the same relative speed. My buddy was taking photos, and the only thing that I lost were the big, billowing sand rooster tails on the high speed turns. It may not be as showy, but it is sure hooked up a lot better and more efficiently than the Bighorns. (I will save the Bighorns for the trails)
I am still playing with the clicks on the shocks, and am 3 clicks from being fully closed on the fronts. Only bottomed twice (once on the front suspension, and once on the rear), and they were not too violent. I will continue to experiment with this settup before considering reworking the shocks. I did feel the reservoirs on the shocks after each ride, and noted that they were getting warmer to the touch. In the future, I may begin measuring and recording the temperature after each ride with an IR gun (old drag racers habit-we measured the rear tire and track temperatures after the burnout) Of course, each weekend I am riding it a bit harder as well.
Thanks again for the guidance one and all.
