I thought i would check the power valves on the Viper today. I was surprised and also dissapointed that they were extremely dirty and carbon coated. Again, cleaned and reinstalled. I would not be a very happy sledder if I had to take the sled to a dealer every other trip North to clean Valves, if I could not do it myself. At this point I could not recommend a Viper to any of my customers. The 700 red head is so much user friendly.
