Took the black diamond can off and went back to stock muffler did not have the problem going to put can back on and see if it goes back to cutting out at 6000 rpm

well ended up that the capacitor for the exhaust valves was shot. new one installed and good to go. was also causing my idle issue. The computer wasn't able to open the exhaust valves half way for start up and idle.
Friend's AXYS couldn't go over 7200 rpm and found all rollers in the clutch shot at 600 miles.
went this weekend rode at cumbres nm sled ran great running 63.6 gram heavy hitters hps can must be magic hit break in nothing changed just ran solid vents r a definite problem buddy 11 pro vents nothing my snow all day
I did it myslef just to save time, but I would be fine with them doing it too. Eric
Had both of my clutches apart this past weekend and checked everything, including the rollers. also rate tested both springs. Cant really find anything wrong. Eric

Have two sleds here in CO with the 5,800-6,000 rpm range bog issue. Mine literally seems to cut out and wants to throw you over the handlebars when it does it. Have to blurp the throttle several times to clear what appears to be excess fuel from the cylinders and then it will take back off like normal and flat rips above 6k rpm.
One sled has HPS can and other is completely stock, both running super rich in that 1/4 throttle area.
Kind of stumped as to what is going on...

Mine did the exact same thing last weekend 3 times. I wonder if it's an exhaust valve issue. Have you had the dealer check the TPS yet?
Exhaust valves on mine had a ton of buildup on them after only 220 miles. The tiny rod going to the cable above the green mark also had buildup on it, enough where it took more force to move the valves in and out. Pic of it is it cleaned. Other pic is dirty valves. I took a razor blade, brake cleaner and rag to clean them up. Prob not the issue with the bog, but people should be aware these valves do get dirty. Not sure how they claim they don't need serviced. Also have a little wear on the pistons already. Not much, but it's there. Using ves gold oil.
Is it possible that the oil pump is adding too much oil during break in? I have 268 miles and about 14 hours and it doesn't have any bog problems and runs great especially on top but if you dog it around or let it idle for too long it will start to load up and leave brown spots on the snow where you idle it.
Has anyone else checked how much oil it's using? I normally top off oil every ride but this last ride I didn't. I burned two almost full tanks of fuel (guessing at about 10 gallons each tank for a total of 20 gallons) and put in almost a full gallon of oil after the low oil light came on! That's a ratio of roughly 20:1. That's pretty dang rich. Just wondering if some of these issues are stemming from a ton of oil going in and gumming up the exhaust valves or something. I ride fairly hard and tend to be wide open mostly all day so maybe that is causing me to burn lots of oil too.

So rode last weekend and had 0 bogs. Maybe it was the exhaust valves after all...

I have 480 miles and 23 hours on mine now all riding done in seven day period I do have bikeman pipe on mine was ran in west yellowstone on non ethanol mode since new never had a single hiccup or big or issue at all two other axys in group both had bogs on and off a couple times and set issues once or twice mine was perfect no issue but I'm 90% sure never had oil dumpex in first tank dealer said they did but no smoke at all says otherwise thinking first tank oil added has something that o do with this maybe
I’m running a 2018 rmk and mine does the exact same thing since day one. My buddy and I bought 2018 at the same time and broke them in together and his doesn’t have the issue but mine does.
This is an older thread however I'm having the bogging issue at 4800-5000 mark. Tps was adjusted to spec at end of last season, still has low idle at 10,000 ft. as of today. idles around 1400-1350 and bogs. Power valves cleaned at the beginning of last season. What has everyone been using for Base and Idle numbers dead on spec. a little over? I have done both and still either low idle and bog. This is a 17' with 1400 on the clock. Updated 18' head SLP stage 3. Was doing it before the head install. I'm thinking clean power valves, TPS adjustment Spec or no Spec that's the big question is there a better set of numbers that work? Maybe a new TPS Maybe down the road. This all started about mid last year, started with low idle and reverse you know the story and progressed to the bog. Same as every other, I'm looking for what has worked? Clutch is good, motor mounts new, has torque arm.
If your having your dealer set you TPS with the DW , you might need to go into the TPS and really spec it out for yourself, as they have a range that correlates as "in Spec"
What your explaining your symptoms are were pretty much cured with a TPS manual setting.
There is a great write up on the procedure if you do a search on here-
Here are my settings what worked well for me,not all sleds are equal so you may have to see what formula your sled likes.
But what your explaining, seems to be TPS related- especially that low Idle.
Base .691
Idle .947
WOT 4.18

They adjusted it once and only did the idle setting with Dw. I have adjusted myself and understand how to. I’m going to go back in and check things and reset. Check power valves and all other things.

New dealer just like the old dealer? Same people different titles. I would have thought different.
What year of sled?
