yes agreed. unless it hits rev limiter so quickly you dont notice it on the gauge or anything. i dont think they have a real sensitive rev limiter like an etec800 tho. ive ridden 2011 etec doo a lot and the rev limiter would cut in like you describe down in lower elevations. and could put you over bars, so it made me think of the clutching i guess.Yes from a dead stop the snowmobile runs like a race sled it does not miss a beat anything from 4000 -6000 RPM you Mash it it will fall on its face. 6000 RPM and above it runs excellent. I took the belt off the snowmobile and I put it on a sled stand and it still creates the bog. If it did not create the bog on the stand I would be chasing clutches as clutches are loadbearing it does it without a belt it does it with a belt nothing changes. I would assume correct me if I’m wrong removing the belt would eliminate the clutches would you agree?
The TPS is something you absolutely do not want to touch if you don't have too. the TPS tells the ecm the the throttle position which adjusts the fuel and timing, Cat makes a tool https://www.countrycat.com/arctic-cat-part-3639-891-kit-tps-adjustment-tool?utm_source=google&utm_medium=cpc&utm_campaign=google-simple&gclid=Cj0KCQiAsbrxBRDpARIsAAnnz_NHure8FpZdI2TlokTOHTU-NRE1U_MWGr1o7Yk5Z_HrmUL7OIJXshYaAjKUEALw_wcB to set the TPS. Was it moved before you messed with it? they have a factory paint mark so they can see if it has been moved for Warranty
