Hey everyone, ive been chasing a rpm issue with my 2011 800 for quite some time now and finally figured it out and just wanna up date everyone has tried helping me out. The symptoms i was having was a wot throttle bog, couldnt get to rev out over 8000 rpm. Everything checked out good/had been replaced. Only thing that was left that i didnt do was the pistons. The sled ran great and had no problems with wot rpm and pulled 8300 with 68g weights at 2000elev untill i hit the 400 mile mark. Now have 900 on it. Today i installed new wossner pistons and wow! Woke sled right up! 8250 rpm with 71g mtx with 3 gram in tip and 1 g in heel. Finally!!!! The old pistons were so out of round it was shoking. Cylinder measured 3.345. Stock pistons were 3.337 ! The ring lands were sloppy as well with .013 play in rings! These pistons only had 900 miles on them and Compression was still somehow 128psi. Oil pump was turned up and is 55-1 ratio. New wossners were 3.341. Little on the tight side! I set the ring gao at .020. After a short break in ride the comp is 130 warm. Anyways im happy!!! Hopefully this post will help some other people.
Just want to update everyone. Rpm and power issues.

Glad you got it figured out! Not sure what to say on Polaris' part. 400 miles is REDICULOUS. Are they buying pistons out of China or what???
You should write them a strongly worded letter.
Wouldn't do any good. You would have a 100 leg humpers writing letters apologizing for my one. Too short of memories and Polaris has been screwing their customers for years. Look how many took the shaft back in 05-06'. And they're still sending out sub-par pistons and look at the people who make excuses for them.

Bigman, You have plenty of your own threads started informing everybody what a piece of **** the current 800 is. Why don't you keep your bashing in them?
Tratch2, Glad you got it running good. Set of pistons once in a while is a small price to pay to ride a package that works as well as the Pro does...
After all we could still be trying to throw around an heavy *** dinosaur like a 97 RMK 700, that kind of punishment could make anybody ornery

Keep on sipping the Kool-Aid..
There is NO point in complaining here LittleMan. You are preaching to the choir. We all already know what potential problems there are with these sleds. We also can read... So we have seen and participated in the reliability polls and we know from this that 85% of the Pro's do not have the problems you are trying to educate us about.
So you wont write a letter to Polaris but you will whine like a baby around here? Claiming your old 700 has a better engine? That is rediculous. The new 800 makes more power and uses MUCH less fuel and oil. There are plenty of them out there with over 3000 miles on them.
You are probably all butthurt because you tried a new Pro and after your big a$$ fell of it you went back to your trail tanks, much safer those low wide heavy sleds. That or maybe you just like making a fool of yourself on the internet...

Tratch2.... 55:1 oil ratio is to lean. IMO you need to turn your oiler up some more. I also run a little in the tank. Your pistons will like for it. Try to shoot for around 40:1 ratio on oil consumption
I forgot to say that i mix in the tank as well, I turned the oil pump up 2 turns from factory spec. Maybe i didnt calculate the ratio right but the sled is using alotta oil. When i pulled the engine apart everything had a nice film of oil. I will get a chance this weekend to do a more accurate ratio calculation.
