I posted an article a while back about the needles, nozzles, oil pump update and how I keep my daughters Super Sport running cooler by adding a heat shield between the pipe and engine. Aluminum shield with reflective heat tape facing the muffler. The top is bent towards the opening in the hood. The vent was notched on the side and heated and bent towards the shield to direct incoming air towards the engine. Works like a charm. The sled starts on the first pull every time....unreal....only Polaris sled that I own that will do this....hot or Cold !! One pull. It got 15 mpg before I changed the needles and nozzles and about 11-12 mpg after I put them in.
