Need some information. Ran great since we purchased the sled with 1300 miles on it. Now at 1900. Now just out of the blue it only runs 15 mph and 5500 rpm. Replaced plugs, coil pack, gas, cleaned carbs ! Compression is 120 with 3 pulls evenly. Fires right up and idles, runs great. Just can’t go over 15. When it does it will do the bogg down back to 15 mph and that’s it. Seems to be a older sled problem with the tss failing but can’t find a thread on newer models. cylinder temps run evenly on idle . Thanks for any information

Welcome
An 03 550 huh
Ok how do the clutches look and what is your center to center on them
Look normal. Haven’t taken them apart. Track suspended off ground and run. Still does same scenario of rpm/cuts out.
