First you might want to check your belt deflection and make sure its as tight as it should be. I've adjusted mine after coming from the dealer for a check up and found it makes a difference in the perf. even on a clutched sled. Also your track alignment and tension affect perf. It only takes a few minutes and cost nothing but can add to the perf. of your sled. Too many people want to start buying add-on perf. and don't maintain what they've got. One more thing (sorry to ramble) adjust your clutch to operate at the specified RPM's. That will make sure your puttin out all you can. Good luck
