I get new polaris mountian sled every other year and just got my axys last week. I will do what I allways do, put fuel in it and grab a hand full of throttle.
(I have yet to have a engine failure)
Does the rmk 800 have a break in period before full power is achieved ? I think the trail 800 axys did last year certain amount of hours
This was last years model

"The new 800 engine will also come with a ‘break-in’ period controlled by the ECU, very similar to what Ski-Doo uses on their sleds. While in ‘break-in’ mode, the ECU delivers more oil to the engine which should also improve durability. This ‘break-in’ period is timed by the ECU and should last around five hours or the first 200-300 miles. Polaris’ current 600 engine also will now have a break-in period, slightly shorter than the 800."

Thats a BUNCH of extra oil. I would buy some extra spark plugs to have with you for the first ride, you might need a few sets.
32oz of oil with a full take of gas is about a 45:1 ratio, which is fine.....if the injection system was removed. Add in what the pump will be delivering during break-in period and your going to be in the 20 to 25:1 range and thats A LOT of oil. Eric
i dont know what ratio doo's etec uses during break it, but it is no exaggeration when i say it used damn near TWICE as much as my buddy's xm that was already broke in (doing the same riding, following eachother around the trees at 8000-10000 feet). so just a heads up to you guys.....if you plan on riding for more than 2 days, BRING OIL!
Since no one has posted it yet, Here is some good reading info.

Ive been breaking in new sled this way since 2002, 2 stroke and 4 stroke. Ive had great results doing this.
"Heat cycles" on a new engine with no load on it is not a good idea at all, just asking to glaze the rings. Eric

Never had any issues with plugs during break in with the extra quart in there.
I let it warm up to 110-120, shut it off for 5-10 mins, let it warm back up. Ride easy a few miles up the road - stop and check everything, make sure no vital fluids are pissing out. Do that a couple more times. Vary the throttle - sleds feel pretty tight the first few miles so don't do anything crazy. Don't overheat it if the snow conditions suck. After its warmed up and loosened up a bit really short blasts of lots of throttle are cool IMO...but I would try to avoid climbing in deep snow or other long full throttle stuff for the first ride. Vary the throttle and accel/decel. "Heat cycles" at home are something that showed up on here a couple years ago....not sure what the logic is but I don't subscribe.
I don't know if people are exaggerating or what...but starting it up and pinning it out of the parking lot is a fairly terrible idea. Even with a broken in motor, full throttle on a sled motor in the first mile or 2 of the day is always a bad idea.

My post from 12/2013:
My MY14 pro had 2K miles on it at the end of last season. I followed the above link break in procedure - possibly sacrificing the drive belt and QD belt for the engines sake. I'm still on the original QD belt and I swapped out the drive belt at 1K miles for good measure. This summer, the engine tested as good as new with only 1 lb compression difference between cylinders. Exclusively use Legend oil.
I'll be following the same procedure with the new Axys.

That Legend Oil is awesome stuff!!
Yep....and in the past they didnt have an electric oil pump with a programmed break-in oil mapping. Eric
Thanks for all the help. Based on the input I think I will do this.
First, warm it up good and cool
Down
Second, warm it up and ride it like my first time on a sled
Third, ride run it like it was my Dads new sled
Forth, ride it like I stole it
Thoughts?

I do almost exactly what you said, except I skip #1
done it on new sleds since 2001 and no issues. One motor I did lose was a used sled that I didn't break in.
