Do the exhaust valves need to be cleaned on the AXYS like prior motors?
Exhaust valve cleaning?

Polaris claims you don't need it near as often. But make sure you don't disconnect the valves as they are electronically controlled. You have to take them in to a dealer to get the timing adjusted.
YES! Mine were so gummed up i had to tap them out with a hammer after 800 miles.
If you remove the cable from the servo actuator and leave the cable attached to the tie bar when you remove valves, you will not have to perform a relearn. Make sure the MAG side and PTO side components stay on the proper side the second valves are not fixed to the assembly they are only held on with spring tension.
To the OP-- they do require cleaning periodically. Most of ours get done at 500-800 miles intervals. The rubber gaskets are reusable-- unlike the paper gaskets of old.

I am guessing you all are using poo-gold?? if not what are you using?
That was my question too, specifically to Indy 500. Regular dino oils seem to gum faster but I haven't had much issue with the legend stuff. Honestly the poo gold wasn't horrible at gumming but it wasn't great either.
Using Polaris VES Gold & valves were gummy/sticking after 400 miles.
Using VES Gold from day one and they were way gummy- second time I have had to clean them ( 1,000 Miles)
I just pull the lower steering post and they have ample room to come out as a unit- and disconnect nothing.. and get them quite clean.

Seems to depend on the riding style. True mountain riding and they seem to stay clean enough....must get burned off/cleaned more frequently with the extended periods of high throttle/load.
I also feel like the internet puts too much weight in to exhaust valve cleaning....they are just kind of a dirty looking thing in general (nature of the beast)....I have never seen any gains after cleaning one, despite reading about that on here for years. But that's just one man's opinion

Thanks for the information. Step by step on pulling them for cleaning would be beneficial.
I have not seen performance gains necessary, I just noticed them not opening at the right time (performance degradation - delay/ hesitation). After cleaning, the RPMs would come up correctly. That was the liberty engine not the new CF with the electrically actuated valves.

There is way to much hype in Preventive Maintenance ???
Seems like the best way to not get on here and Put "It won't pull RPM "
Then a whole list of of did you Change Motor mounts and Torque Limiter ?? Exhaust Valve Cable ?? Both of which cost $115 for parts and a half hour of Change out !! New Belt ?? Deflection set ? Clutch Healthy ?? Gas Quality ?? Outside Temperature?? Elevation ?? Then it all comes back to the gummed up Exhaust Valves and you spent a week trying to find it ..
Guess I'll clean them !!

I have 2,100 miles on my Axys valves, they still pull easy. I have never cleaned, just perform an occasional pull test by hand.
Must be that good, clean Lamoille Canyon snow that you fellas rip up.:face-icon-small-ton
Both Polaris dealers in my area told me they are self cleaning. I'm not sure myself.

well its just my opinion but 500 miles seems a little excessive but if you don't lay eyes on them every 1000 miles....that's just neglect!!

I clean mine every 500 miles, they usually have quite a bit of carbon on them. Probably doesn't hurt anything but id rather have them clean for piece of mind.
Right!
I kinda thought the same thing. I don't understand how they can't get dirty. My 15 800 I cleaned those and they definitely needed it. Sent from my SM-G900V using Tapatalk
I wish I would have taken a picture of the dirty valves.In the pic those were the best we came across prior to a good scrubbing
"Mountain riding" full pin most of the day so we are generally full on/off the flipper... working the crapola out of the fluctuation of the valves.
There is a scraper that runs across 1/2 the valve that is supposed to be the "self cleaning" sales hype .. Pulling on them does nothing to let you know if they are clean--- The springs alone get caked pretty bad with residue and don't like the extra weight of the oil hanging on them either.
For the time it takes to clean them , with the annual PRE-Maintance.. its a cake walk.. but then again- fully greasing the suspension on the shafts that don't have zerks that do move..( Mountain Hourse has a GREAT write up on this on the forum) some just don't like to take the time....
And.....Thats ok too... keeps me in business....
