Power bog and Powder bog?

[LandonP86]

Got a 2013 800 Pro that I just got back from Cooke with. The first few days before we got dumped with snow, it would periodically bog from WOT to about 5500 generally after a restart, I could watch water temps go crazy at the same time from 130 to 165 then to 105 and then climb back to 127 and as it would climb back to 127 it just didn't sound right, not bogging but just like it was almost missing. This stuff pretty much stopped after the third day. But then started powder bogging as we got dumped with 3' of super dry pow. The next two days it ran good majority of the time but would bog like before any time it got any snow over the intake and even after I would clean them off. You could see snow under the mesh but without thawing my sled couldn't get that out. Is there a better intake setup I can invest in? Or do I got something else going on it? Sled has 300 miles with a SPI carbon fiber silencer. Other 2 2012 Pros I rode with had a few powder bogs but nothing like mine did, thanks for the help.

Sounds like tps. My 13 has done this. My dealer has adjusted it 3 times.
Your timp spike and drop is when you shut down the motor is still hot and continues to heat the coolant in the motor . The coolant in the cooler starts to drop timp right away. That's the reason you have a spike then a drop after starting back up.

Ok I'll do a search on it, I've read a little about it but figured it was something else.

Thanks

I seriously doubt the bog is related to powder or the air intake. Last Sat. the snow was over the hood deep all day long. I runined a belt, pulled the cord pretty good, but never felt the engine miss a beat no matter how much snow was on the stock intakes.
