Mine is worse when I am running the 10% ethanol resistor. Non ethanol resistor and the best premium fuel I can find makes it run better but I am still experiencing some bog ever now and then.

"While you fellers are looking around in your engine compartment, you might also check the wire(s) connected to your Exhaust Valve Solenoid. A riding pal of mine has an '11 Pro and it started running like s**t. Hit the flipper, pulled hard, then would suddenly shut down and then would start pulling again. Dealer put the D Wrench on it and it threw a code for the EV Solenoid. Checked the wire and it was completely shot. Rewired and now it runs perfectly. A case of another electrical gremlin. "
I posted above comment a few weeks back on another bogging thread. Wouldn't hurt to check the wire.

Does your sled act like mine ----> http://youtu.be/uv1ZTrg0Qzc
??? If it does maybe we have the same probs.
I have a 2011 that is bogging. Just happened the other day for the first time. Check engine light would flash on, sled would bog, I would come back down from a climb and it would be fine for a minute. Did this two or three times and then the light came on solid and won't go off. When rev'd, the RPMs won't go over about 3600 and it just bogs out at that rpm until I let off. Never had this happen before and I just happened to pick it up from the dealer and this occurred on the first ride out.
I have an after market kill switch and it wasn't hooked up. I had them re-connect it and after they did they told me my sled through a bunch of codes. Most were all old it sounded like so they cleared them all out. Rode good for about 15 miles or so and then I ran into this issue. Would hooking up that relay or messing with the wire connections cause this issue possibly? Taking it in on Tuesday to get checked.

Yes mine is very similar, mine sled is even an orange assault too. I have a video of mine bogging as well, but because I have a Jaws can it is a little more noticeable in the video just by the sound. I will post the video when I get back to my computer next week.
I rode mine again today and my bog isn't as bad after going over it, but still not gone completely. I am going to have to bring it in I think and have them test the injectors and maybe try a different ECM. My warranty has been up since october so it'll all be out of my pocket now.

Seems to be worse when I put the 10% ethanol resistor so when the sled run richer.
So what can make the engine to bog more when it run richer ??
I also notice that this bog happen more at higher outside temp.
I also try different fuel adjustment with my PCV and the richer I run, the worse it was.
I will install my afr this week so i will be able to check what it happen when the bog occur

Sounds very interesting with afr, update us directly
I have some new injectors and a ECU to try tomorrow..
I dont know but witch way should the sil/filters be in the tank? ive heard about a arctic that the filters haved turn down in the tank so it couldnt get enough fuel when he pinned it. Could be worth checking it on the pro ?
Just checked the filters in the tank and they are supposed to be with the suck side down.
The issue on my 2011 ended up being a problem with some loose wires in the throttle/kill switch housing and it was bogging due to the throttle over ride sensor i guess. Easy fix. It was keeping the clutch from being able to engage.
As posted in the another thread, my 11 Pro, out of warranty, just started bogging unpredictably but somewhat frequently at WFO, no codes, just starting to dig through it. It will be time to make it someone else's problem after this season. One thing is clear from riding, boards and my buds who run all the brands, these poo CFI-2's have way more electrical gremlins like this than all the others combined. Personally, my etec and ptec doos have been flawless on runability, for years, still have 3 of them, but the Pro chassis is so much better. Always an adventure.
Got my pro back today from the dealer. They tested injectors and tried to replicate my bog and couldn't get it to do it. I plan to ride it this weekend and see if I can make it do it again.
did u ever try with the stock can on ?
2012 pro rmk 800 cutting out
Guys i know most of you hav been talking about a bog but mine will scream when pinned or sometimes even like jus off full throttle for like a 1/4 mile to 1/2 mile down a trail and around 7600-8000 rpm it will cut out and fall flat on its face to where it about launches you over the bars!!! You hav to let off the throttle and then when you pin it again it will keep cutting out around that 7600-8000 range!! Digital wrench showed 13 overheat codes when the hottest it ever got was 135 and on trail stayed at 125 all the time!!! They are checking tps, injectors, fuel pressure and changed the temp sensor amongst other things but everything shown ok!! They are waitn to hear from polaris as they are stumped on this!!

I did yes, no difference tho. Still more prominent on the 10% ethanol resistor.
I just installed a rk Tek drop in kit n have roughly 250 miles on it and tonight while in powder at WOT, I hit a slight bog. Got off n on the throttle n not that exact moment but it did eventually bog out again 1/4 mile down the road. Changed plugs n made it another 1/4 mile and it bogged out again.. Got on hard packed trail and went WOT and had no bog. So it seems like it occurs only in the powder. Lemme know what you find or if you have any ideas. Thanks
I also find mine generally does it more in powder vs. hard pack or even lower snow conditions.
Assume you are not hitting the rev limiter, no offense, I needed to add 2 grams heavier weights or I would bang the limiter consistently. It can happen so fast the tach can't keep up. I am getting an occasional bog now, over 800 miles on the RKT kit in an 11, but I doubt it's the kit itself. Just started. PITA.
Running 68g weights.. not positive on what rpm im at with WOT. Sled only seems to make this slight bog in the powder rather than hard packed. So not thinking its the rev limiter, but something to try and watch while riding it
Okay so I've been battling this bog issue since my 2012 800 Pro RMK was new in December and now have over 530 miles. I've experienced a bog at random throttle positions including WOT. The bog seemed most noticable at engagement RPM after engine had been shut off and temp was in the mid 90's. The dealer checked but did not replace the TPS. The dealer replaced the injectors at my request. At this point nothing has resolved the bog. After a ride yesterday in deeeep powder (30") I was having a lot of bog/shutting down issues that tripped the check engine light and was probably associated with snow around the throttle block. I don't consider the amount of snow that was on the throttle block excessive by any means and I even cleaned it out occasionaly. In my opinion this amount of snow should not cause issues with the throttle safety switch!!! After it got dark we turned around and started down the road. I experimented with different throttle positions to force it to shut down and found that with the throttle engaged at any RPM if I push directly down (not to the grip) towards the ground the throttle pin will lose contact with the plunger that switches the throttle safety switch. I hope bypassing the throttle safety switch will eliminate my problems! Maybe this will help some of you as well.
