Polaris update

[2007dragonman]

tips

Guys that are having problems with scoring you do have the 2 ring pistons, computer map and head installed? Also remember the coating will wear off and look scored but not be actually scored. Also do you have your ethanol wires unhooked. Also make sure you have new gas it does not last long now days. I think warming these sleds up will help alot exspecially since the clearance is tighter now. Also put a little octane boost in because you should put a half of a quart of non synthetic oil in first tank and could bring octane down a little!!

I hope all works out.
ares are running awesome!

d8 will not start after running

I also had the same issue with the sled not starting after I rode it about 10 miles with the updates.
Turned it off to chat with friends and it would not start.
Pulled the plugs and they had spark.
They were very wet. Let the sled sit for and hour and it started again.
Is the mapping off?

What kind of oil were you running just curious?

Polaris gold with a pint of blue in the fuel tank.

Those that have flooding issues have you tried holding the throttle wide open when you start it?

On the 08 700 sometimes I've had to turn the key off and push the kill switch down and give it a couple pulls then turn everything back on and it fires right up.

everyone does know the more oil you add to your gas the "leaner" the mix is ..right?

Do the new two ring pistons even have grafal coating like the old bigblock 800 elko pistons or not. By the looks of mag's photos and the way mine looked it appears they never had any to start with. I also ask because my dealer said mine did not look to bad, just very minor scratching and normal wear. They said the coating wears off quickly. On my old bigblock I had about 800 or 900 hard miles on a set, even had some detonation and when I tore it down the coating was like new, hardly worn at all. I am just skeptical of there answer, they also said it looks like it might have ingested a little dirt and asked if I rode on a dusty or muddy road. I will look at a set of new pistons when I pick up my sled from them hopfully today. I know I have been around this stuff long enough to know when something is wrong, but I guess nobody is perfect. I hope I am totally wrong, we will see I guess. They also told me polaris said nothing about adding oil to the first tank, which I dont beleive it needs it. To my knowledge the extra oil in the first tank is just in case the injection system has some air bubbles.

Thats exactly what the dealer told me to do

How can one dealer say this and another say that and the third just throws their hands up in frustration? In September I received a letter telling me about the update for my 08 155 Dragon from Polaris. In the letter was all the info on the update and info on the break-in. It was clearly stated in the letter to mix one liter of Polaris Blue in the first tank of fuel and also to run one container of Polaris Blue then switch to Polaris VES Gold Plus(this part about the blue and gold was open to a little interpretation). Did everybody not get this letter? I had however traded my 08 for an 09 163. Update obviously was done and I have only about 65 miles on it but it runs like a top, even with the initial oil in the tank. Got another letter from Polaris after the update was done on the 09. Did everybody get that one? Got a third letter yesterday from Polaris with a questionnaire on the Polaris products and dealer service and quality of. I FIRMLY BELIEVE THAT POLARIS HAS GONE TO BAT ON THIS ENGINE ISSUE AND I AM VERY CONFUSED ABOUT ALL THE MISS INFORMATION THAT IS OUT THERE?

I think I have been around too many other brands. Although, I am not a professional engine builder by any means. These are just my opinions on this, but what Polaris considers "normal wear" everyone else tosses. And my question is why would the coating wear off? It shouldn't. This can only occur from heat or poor tolerances causing the piston to directly contact the cylinder. Scuffing, scraping, scratching is all bad in my book. If this is truly Polaris's stance on that, then I think they have some quality control issues.

I agree that Polaris is really trying to stand behind this motor. I'm hoping they hit a home run with the new update. These are great sleds they just need to prove the motors are worthy.
I think the info just doesn't always reach the consumer. Whether a person didn't receive a letter or the dealer doesn't relay all the information. If I have learned anything over the past few years it is that Polaris isn't very good at communication with their dealer network. It is not unusual to find more accurate information sooner on Snowest. I've called dealers numerous times asking for more in depth information on topics they haven't even heard of yet.

 

[hilinerider]

i wonder if some of this is from not enough oil upon assembly?

 

[icr]

I've heard the new pistons were .010 over....but dropped into the same cylinders. Can anyone confirm that?

 

[HECKS]

F.Y.I. - If your sled happens to flood and won't start. Trace your electric fuel pump plug (above the airbox) and unplug it. Then pull your sled of a few times and it will start. Plug the fuel pump back in a give'er. Quick fix until your riding day is done. Mines back at the dealer now, trying to figure out the problem. Seems that after the first pull the pump is over priming the injectors.

I can't even imagine the sled being able to run with 1 liter of oil in the tank besides the injection...LOL.
One thing I am begining to wonder about is the cylinders themselves. They are saying the new 2010 cylinders have longer skirts that extend into the crankcase. Polaris has done this for a reason, namely to stop piston rock. Maybe they were hoping the 09's with the new two ring pistons would get them another year or so to get these sleds off warranty and off their backs. I wonder if the 2010's will have the same trouble?

It's .009" to .010"

Sources: "Phat Bastard" on H.C.S. approx 1 1/2 to 2 months ago and

Casey @ Team Bayport Racing info posted on DYNOTECH as they replaced both pistons and honed the jugs in their dyno room October 12, 2009 on a 2009 D8 with only 1000 miles on it. That info is still on www.dynotechresearch.com

 

[shortstuff]

so has anybody that runs redline checked there pistons yet or had this issue?

Engine Oil Break-in Recommendation
Polaris recommends using Polaris Semi-Synthetic Oil for premixing the first tank of fuel at 40:1 and for the first fill of the oil tank.

[zach13]

makes me wounder if they forgot some asembly lube.

 

[SNOW JW]

Mag I sent you a PM sorry it's a little long hope it helps.

 

[cascadesnowjunky]

shortstuff I run redline race oil, and rode the first ride with it. I did not siphon it out and put polarises oil in it. I have broke motors in with it before, in fact when carls cycle ported my bigblock 800 they told me they break all there motors in with redline. I have had good luck with redline oil, I think it is outstanding oil and beleive none of my problems are oil related.

Not sure why I would say the sled runs like a top either then. Here it is again from a post in this thread:

Lets do the math. Tank has a capacity of 43 liters. Add 1 liter of oil, that's about a 43:1 ratio. Close enough to the 40:1 Polaris is recommending.
