are motor problems the only reliability issues with the 800 RMKs?

Early on in the dragons their was a recall on the pistons. I was one of the unlucky ones that my piston cracked and destroyed my motor. The cracked piston went through the case. It also took out the intake/injectors and the head. It was 3500 dollars to repair but was covered under warranty. Then my voltage regulator went out taking out my ecu. This seems to be a weak link in the dragons as you will read and see that many have had their VR go out. My were replaced under warranty and apparently replace with an update VR. Polaris then came out with a new updated piston and head which I had completed in Feb., under warranty. So if the you are looking at getting a dragon, and the 2010 update has been done on it, it should be relativity trouble free now that it seems the major problems have been ironed out. Mine is an 2008 with 1000 miles on it but only 100 miles on the new updated pistons,head,vr,ecu.

Keep it stock, Pull the rope and go!
Have an 08 800 dragon. Had 2800 miles on mine before the update and at 3500 right now. I have not had any motor problems with mine so far. Has always ran great.

thanks for all the replies and info! been mowing a lot of lawns to save up money so i can get a 10' Dragon 800 RMK 155. sounds pretty reliable to me.
Buy a 2007 -2009 700... much better sled for you.. much more reliable with plenty of power and will give you no headaches....less money for the sled means more money for gas.
My stock 700 gave a lot of stock 800's a run for their money or even outdid them... some of the 800's dont run well, some rip.
Keep it on your budget and focus on riding more. If you are pushing yourself to learn, you'll be putting all kinds of scars on the sled anyway.
Just my 2 cents.

If it was sold as a mod sled, then I'd agree with you. But this is supposed to be an EPA compliant, fuel injected sled. Riders should not have to continually burp the throttle all day. I agree with you on how they need to be ridden however, I disagree on why.
Before I installed the PCV, mine would lean sputter on inital throttle tip in (takeoff) regardless of how much throttle opening was commanded for the first minute and a half of every start up.
How do you ride that correctly???
Ski Doo's SDI 4 injector motors which were nearly identical to the CFI did not have to ridden this way.
I let mine warm up and I don't have that issue but I know what you are talking about. it has to do with the exhaust not being hot

sounds good, probably wont need an 800 while i'm in the learning stage anyway... yeah, i'm definetely pushing myself to learn, before the season my sled was mint now it's not even close

Doo has the patent on overlapped injector timing. P must be off or on with the CFI-4. Just the way it is. Becomes more critical on the 8's - more fuel required - to avoid lean condition in the midrange when injectors must transition. There is a reason why 2011 800's are CFI-2's now.
As do I... Water temp and exhaust temp have nothing to do with the symptom on mine. You can shut the engine down at 125' F after riding for 30 minutes, restart engine and have the exact same coughing, lean stumble. Doesn't matter how long it idles for.
Adding between 5-8% more fuel in the initial throttle opening (1-10%) with the PCV solves the symptom.
You could sponsor my sled with a turbo.
Ellaborating on this issue even more...A cold motor should be getting more fuel than warm. The tricky part of this with the mapping is not creating a plug fouling issue at the same. Aren't plugs cheaper than pistons and mono's??
If I was you, I'd get a 600 before I'd get a 700. The 600's are a much funner sled, lighter, and faser revving. I would try to find an 07 or (08 shift) carb'd 600. Many more cheaper motor options. 600 CFI would be awesome as well but a carb'd 6 would be dope (as they say)
