Yes, weight/rocker bushing in the primary. periodically it would get thru 7400 to aabout 8200, but if travelling thru the field and hit it it would stall at 7400 and pull down to 7000.

I had to do that with a street bike once, but mine was all dealer related.
Regardless, I can sure feel your pain. This should be a fun sport above all. It can be very frustrating when a company like Polaris won't just step in and do the right thing. If your dealer can't fix the problem then the sled is broken and should be returned. Or, Polaris should send out a factory mechanic to fix it. 3 years is far to long to be dealing with the same problems over and over again. There are some great running 800's out there, but there are quite a few not performing as advertised too. For a company that has been doing this as long as Polaris has it is just plain embarrassing that they can't get this right. And even worse that they won't exchange the problem sleds to save face. In the long run this would surely have cost them less money and ensured return customers. Now many Polaris riders are being alienated by the company they have stuck with for so long. I'm loosing count of how many people I know that have jumped ship this year. Polaris isn't making it easy to stay loyal that's for sure. Sorry to get off topic there, but this poor guy has been battling this sled since day one.

Just had the latest reflash done and gave her the test. Seemed to climb with much more power than the 09 map. No hickups what so ever except for a slight hesitation from idle. Idle seems a bit on the rich side as I now have some tell tale signs on the snow.
All in all felt pretty good.

What is our target rpm on the 800, 09 with slp can and pcv, I have been shooting for 8250, is that right? Also does anyone know if dynotech has released a new map for the latest polaris reflash?
Rode Saturday on the new flash and sled ran exactly the same as the stock program (mine is a 2010). Still have the mid range stumble at low elevations that goes away by 6000' but once up there the top end power drops. Guess I'll call the dealer tomorrow and give it one more try before buying the PCV.
2009 or '10?? This sounds kinda like mine. Seems to run pretty good in powder (off and on throttle), but when trying to hold the throttle at about 7-7500 rpms' on the trail it cuts out something horrible. I just had the new reflash done on friday, and it is just as bad if not worse than before. If i knew a pvc5 would solve my problems i would pull the trigger, but i am beginning to wonder now. Also sled will only pull 8k now, before it used to hit 8150.
You pretty much hit the nail on the head for me too. 2010, reflashed last week, and the only difference is i lost my top end. Worse now than before!!! Does dynotech jim have a program for the new flash dialed in yet??

The new flash didn't change top end, I'd look for something else. Carl's told me it was to help the map at lower R's where the EPA emission check points require it to be lean, 4000 and 6-6500 RPM.

Your dealer might have disconnected the pipe sensor wire when doing the update. Or bad fuel, fouled plug, etc. Or your dealer may have installed the wrong map. There are other possibilities.
An unpluged pipe sensor should make the check engine light flash. I would change plugs first. these sleds seem to semi-foul plugs. where they still idel but maby a little low, and dont quite rip on top like they should. i have 600 miles on mine and have probally gone through 6-7 sets of plugs.
Mine has lost 300 rpms since the flash. I will try plugs and a new belt to see if
this brings it back to where it was.

I just noticed that you are at low elevation. Maybe Polaris made some map changes that cost you power at low elevation. Relatively speaking you will run heavier weights and lower throttle positions than we do at altitude so your oringinal theory about the flash may be true. I can get mine too lean at low R's with light weights.
Sorry for the late reply to the question posed to me earlier:
I had heard from my dealer Polaris was testing some new maps in different regions.
The question asked was: Did he tell me where those regions were?
Answer: yes, he did tell me, but I don't remember, since none of them were close to me. - sorry.
I live in Western WA, Just north of Everett if that matters to the answer.

Sorry bad news. I still have the problem. It is on a 2008 D8. Latest Flash has been done and still had the problem. They tested all senors, ecu, stator, changed fuel, plugged and unplugged the ethanol wires. They have tried all color fuel injector maps, went thru both cluthches, new plugs. Dealer has been riding it and says it is getting better, but still a problem. Belt is new. Ran it down and put good fuel in. They have swaped out exhaust valves with another sled to eliminate that. I ride flatland at 2000 feet and i swear it was working good at 4000 couple weeks ago. Might take it back to 4000 foot area this weekend and see if it works. When you start the machine up, warm it up, and then run it it will hit 8200. Back off and then hit it again and all it will get to is 7400 then detonates back down to 7000 with a detonation bog (seems like half the motor is running, falls right over). But no detonate lights come on. Standing on the jack stand it will consistently hit 8400 rpm, but not under load. Dealer has been excellent and if we find something will let you know. He is going to try 66 g weights (have 68s in now, which should be correct weight). When i got it i rode it with 62 gram weights and it was overreving on flatland (which it should), but i did not notice this bogging issue.even loaded up with oil in gas.
IS this what you are seeing at all? If PCV works let me know, seems we have a similar issue. Seen another thread where the guy mentioned similar issue to us. They took some readings off it today at idle, mid throttle and pinned and sent some "data" to Polaris. If anything comes back i will let you know. Sounds like Polaris has been working close with the dealer.
Dave, has the dealer checked the tps with a multi meter? or just with digital wrench?..it needs to be checked with a multi meter..its more acurate then digital wrench..also have seen a couple of sleds that were acting up fixed with either an egt sensor or a air temp sensor(sensors all tested good on digital wrench) theory was the sleds were injesting lots of snow around the headlite and contaminated the sensors...also what octane fuel? seems the sleds dont run as good if they have to much octane....(stock mine ran better on 87 octane then 90 octane)...
I will check on that tps issue with the dealer and ask him, thanks. If i tell him to check with multi meter what is he checking? Maybe he will know that. I am not overly mechanical. I kinda think he was using a multi-meter when i was at his shop, but will check.
You have jogged something. When i went to the 4000 foot riding area we got there late and i had to use 87 (regular in canada) and it worked. When i got home i put in 91 (premium) and then was having the problems. I thought it was the elevation that maybe made the difference. I hear so many people talk about good fuel that i never thought about it. What was yours doing with higher octane???????

Mike, we have 5 in our group running 1/2 av gas and 1/2 90 octane as suggested by our dealer and ours run just fine. We might be losing
some in performance though?
mine will hesitate on initial throttle tip in..still does..and it does it at low elevations..once I get up over about 2500 ft it goes away..that is due to a programming glitch in the ecu(polaris has to have these sleds lean at the epa test points..idle, 4000 and about 6500 rpm..which is where everyone has the issues..a fuel programmer will solve these since you can adjust the fuel map richer as you see fit..but..besides the controller you are also looking at at least a set of egt guages and learning how to tune your sled in to avoid being either too rich or too lean....the latest map from a week ago should solve most issues unless you ride in an area where there is a glitch in the program(you have to realize..besides the actual fuel curves for rpm/load related mapping you also have elevation and temperature compensations as well..so in certain areas/conditions you may end up lean/rich regardless)there are things that help..heel heavy weights that load the midrange help on most sleds,more initial helix angle will sometimes help..even different octane fuel can help...for those that dont wish to run a controller I am trying a few things to lean the topend that might work for the masses..but so far I havent gotten enough difenitive testing done to say..
