2011 Pro Rmk Mid-Range Throttle Bog

[DDebert]

Having alittle trouble finding other threads on this.. 2011 Pro rmk with a mid-range bog, 1500 miles with only mbrp can on it. When riding at approx 5000 rpm then go to crack on the throttle sled gets to 7500 rpm and bogs right out, get off the throttle and back on the bog is gone. If you roll on the throttle instead of an instanatious hammering it also rolls past the point where it always bogs and pulls 8200 rpm. End of last year pulled exashust values and cleaned them checked the bladders and it got rid of the bog for probably 100 miles then it started to occur again. Was just wondering if anyone else has heard of a prolem like this or has any suggestions.

what are you running for clutching and at what elevation?

 

[DDebert]

stock clutching with 68g @ 1600

 

[gedakbx]

that should be enough weight at that elevation for sure Fuel filter maybe? Have you checked your compression lately?

Had an issue with my etec, was the can. Had weird midrange bog, put stock can back on and was cured.

It's likely your TPS Sensor. Had the exact same issue on my 12 last year. Are you getting a warning light on your dash as well that comes and goes?

I had a similar issue and it was my EGT sensor.

Not the can tried the stocker and same thing also no warning lights. Gonna check compression and fuel filter this weekend. Could it be a problem with the mapping of the ecu had it replace about a year ago and not saying its done it ever since but it has been occuring for a while

My warning light only came on when the actual bog happened, which was tough to catch, because you need to be staring at your dash while you are hammering it wide open. Your dealer can plug it in and run a diagnostic, but that could come up with nothing as well.

How is your throttle cable free play?

Fine, my issue was the TPS sensor. I guess people were having issues with them getting wet and it was causing issues. Since replacing that, and putting FrogSkinz on all my vents running without issue.

What color of injectors do you have? If you have anything but yellow, you should replace them. Good chance thats your problem. 2011 had problems with injectors. You can only replace them with yellow now. Polaris won't even sell you another color. I have also seen 2 sleds where the harness on the injectors is rubbed and the wires short out.
