I picked up my 09 Summit 600 etec from the dealer a couple of weeks ago in MN. They stated it comes standard with the high atltitude clutching. They had no idea on what to run for below 6000ft. I plan to break it in the UP of Michigan (~1500ft) before making any runs out West. Does anyone know the proper setup for low altitude on the 09 Summits? Any help is greatly appreciated. In my past experience with Arctic Cat, they sell a low altitude or high altitude kit that comes with the proper springs, weights, and jets if applicable.
