11' PRO RMK- Cut out @ 4300-5200 rpm HELP?

[routtrider]

Up till this weekend my PRO has been perfect. No problems at all till 650 miles. We went to the flat tops which are a higher elevation than I have riden at w/ this sled. (11,000-11,500), Again the sled has never done this at all.
So were climbing up the mountain and once we got on top i was doing some downhill U turns and it started to cut out right as i was getting on the throttle going back up. I flew into the handle bars is was so bad. It kept doing it the whole time I was riding that high.
On the way down in ele. it stopped doing it? I havent rode it since to see if it does it still but i am sure it will. HIwayman seems to have a wot cut out but mine is right in the middle? HELP please.
I want to go to the dealer w/ some info so they are not screwing around trying to find it? I am sure some of you have had this issue and have the solution. My friend Elivis1280 made me join last night, he said this forum is the best and you guys can help! I have been on here all year reading and thank you for any answers.
What is a TPS?
could it be the injectors? or the TSS?

Was it only bogging when sidehilling with the exhaust exit in the snow?I have run into snow conditions where the sled will bog anytime the exhaust side is buried in the snow, I think this is due to a denser snow pack and the fact that the exhaust difuser doesnt stick down as far as previous models..so the exhaust builds to much back pressure...i am going to lengthen the difser another 1" an see if that fixes it...

AK, it was doing it on the flats, snowpacked trail, u turns on clutch side etc. I wish it was just an exhaust bog but I am sure its something else. It seems to be the same thing as a lot of other PRO's? IT also seems to be happening around 600-800 miles. Thanks for the response and I will check that.

Mine started out with a mid-throttle split second cut out. Then it turned into a full bog. Most of the time it is at WOT, but once in a while it is just off of WOT, 7500. The cut-out was around the 5-6k mark at first. Good luck figuring it out, what a frustrating thing!

thanks for that HIway, I am helping him with his sled. I was so ready to dump my 10' M8 LE and get a pro? But like you said up top, I haven't missed a beat in 1703 miles on my cat? But i love the pro just kind of scary. I have never missed riding a day cause my cat was in the shop. I do all the work but it was nothing i couldnt do myself. (servo motor replaced, helix broke etc.) something like your prob I wouldnt know where to begin.

Check the 2 prong diagnostic port wires up by the hood hinge. Some guys are seeing a problem with them grounding out on the frame causing a bog around 5k.

I have this problem too, it really only happens on turns to the left in the trees or just off idle. Had the pipe sensor go bad the other day and thought maybe that was the culprit the whole time, replaced it and....Still doing it intermittantly??

95% of the time the thing runs perfect, judt that other 5%..

You both mention it happens when you turn, I found a few wires shorting out where the frame and steering post meet. On mine I also found a short on the injector wire grounding out on the fuel rail. When this happened to me it felt like a bog, or a miss. Hope this helps good luck

It needs injectors. They will clean up the mid range bobble/miss. Fixed mine.
