I am having the same sort of problem. The deeper the snow the more bog. Rode one 2 foot plus day and it was hard to get the sled to rev up after stoping. It only happens after I stop. Once it revseems up it goes.
I have a slp can clutch weights and spring. For over 10,000 feet.

Have you sealed your exhaust pipe with rtv?

Yes I did. What would it affect if I didn't?
I see a lot of talk about moving relays what is going on there?

Carbon monoxide filling up the engine compartment in deep snow, especially when stopped for a while. It'll displace the oxygen you need for combustion.


Relays can get corroded from water intrusion if they're in factory location.

When I have been riding in deep snow I have just been cleaning off the vents for the engine intake because I thought that was the only or actually vents feeding the engine I thought the rest of the vents were cooling. Should I be cleaning off all my vents when I stopped in deep snow?
What relays should I move and where do I move them to?
Thank you for all your help! I am a little lost here it just a little frustrating when it is the best powder of your life and your brand new sled does not want to go?

Intake systems are not perfectly airtight under the hood. Rubber gasket on the can exit can be pretty loose. In deep snow, particularly with low ground speed but high rpms, exhaust gas out of the can gets blocked, and can be sucked up between the rubber gasket and can, and you'll bog from lack of clean air (rich bog). RTV the inside of the can/gasket minimize this.

I cant imagine underhood gasses would cause a problem. Even with a leak, 99% of the air would still be coming from the outside vents and inhaled into the engine. It might be good to take back to the dealer and have them dig a little deeper into this.
