So far 50% of the 800 Dragons with the new reflash run excellent but 50% are blowing up under 100 miles!!
What has anybody else found out?
The dealer told me 3 out of 6 burned down the motor under 100 miles.
So I did not want to take the chance, but the reclutching from 68 grams to 70 grams major difference put on 400+ miles this last week.

I had my Assault reflashed last week, it does seem to run alot better. I only have 70 miles since reflash but no troubles yet. I did read on HCS that there is more then one version of the reflash and to ask for the most current. They had a list of the exact codes available. My dealer told me they have had only one Dragon with similar trouble. I will update if any further issues.

My buddy just bought a 800 Dragon RMK 155 and has 400 miles on it. Reflashed when he got it. No problems.

I just bought a 09 800 switchback last week. same motor as the dragon. The dealer did the latest flash before it left. put on 225 miles this week on it seems to run great. Squeezed the throttle for a short, easy 105mph

Thanks, I only did the 70 gram weights in the clutch, big difference from the 68 gram weights waiting on the latest reflash for my 800 dragon and 800 IQ.

There was three re-flashes that came out,because there is three different injectors red,blue and yellow.The way to tell which injectors u have on your sled is to lossen two screws on clutch cover(plastic piece sits right on top of clutch cover)lift up cover and it is written on a sticker which injector u have.Now I heard there is another re-flash coming out but since mine has been running better with the first re-flash i'm waiting till the end of season to find out if they indeed come out with another.

I havent heard anything about diff injecters? I have only heard of TWO reflashes and the third is on its way. I have only had the latest of the two and it runs great with the exception of a 4500-5000 burp oncwe in a while

The dealer told me when you do the reflash thats it, no 3rd reflash, you can only do one reflash is this true?

NOT TRUE 3rd flash is the one you need. Most current. you could have had all three it doesnt matter its just a reprogram

The dealer said Polaris has found the piston rings are breaking and might have a recall on all 800's for new pistons and rings this is what they found that is causing all the motors to lock up?

Dealers from Ill, and the dealer in Wisconsin, 10 out of 25, 800's range 100 miles to 1,500 miles the pistons break.
50/50 chance it will happen.

If anybody is looking for one of these sleds I have a 2008 Dragon 800 RMK with 2500 miles and a 2009 Shift 800 RMK with 2400 miles and a white hood. Both have fresh rebuilds and have been reflashed however I'm unsure if they have the latest reflash.

Dealer in wyoming told me they were takeing the thermostats out because it was a heating issue that was making them blow. But they would not do it for everybody because some people would not let them warm up properly before rideing.

Yea I still have that here too however we did make a little headway on the clutching but I'm thinkin the bikeman clutching is going to hit the road! Haven't figure out how long a belt should last with 230hp but I'm hoping it's going to be more than a 100 miles!
