Question... I have a 2015 Pro x rush 800 1.75" I never ran it stock I just bought it with 2000 miles on it and did the following... slp stage 2 kit ( 71g mtx weights with 2g tip 2g heel ) pipe and muffler with resistor, Stage 2 springs, New engine mounts ( Heard they were an issue ), slp torque arm, air box mod ( slp ), New polaris belt. Sled had 22-40 gearing before I bought it. Sled would only pull 7950-8100rpm, seemed to fall off pretty good at around 80mph. pulled like crazy 0-70! marked the clutch and was using all of it. Pulled 2 grams out of the tip for more rpm pulled 8200 then added 23t top gear for 1.74. Picked up some mid pull and a bit more mph. Seemed to still not pull real hard much over 85. Found running 3/4-full throttle was no change in performance.. Had polaris set TPS, calibrate exhaust valves. TPS was out.. the 3/4 to full throttle issue is now gone and more linear but still no more rpm. Thought to myself lets try stock 66 weights. Should scream... NOPE! 7900rpm!! it dropped! ok lets put the stock spring in with those weights then... Nope even lower 7800rpm... Put the MTX 71 with 2 gram in the heel back in.... 8200rpm was back again.. Any ideas why its not pulling 8450 like slp says it should? Raced a geared 1200 skidoo and pulled it 0-70 and it went by at 85. Just feel something is wrong. I know they arent a lake racer but feel it should have more on top with the extra hp from pipe and the taller legs from the gearing. Tempted to put it back to 100% stock and see if its way down on rpm?? ANY HELP!!
