Polaris update

[gerrman]

i just had to come back to this post to add..my 08 d8 slp pipe air vents and intake, helix. has never been a good sled untill now. 2010 update 65miles on it..and it ****king rips! the rpms were a bit low for the 1st few short rides now it hit8250 hard pack and 8150 in pow..it ran so good i stopped at the dealer and said it must be ready to blow up now. only thing i did notice was the temp.. it ran 122-129 until the road back to the truck then it hit 140 but it would jump from 122 up to 136 then 140 then back to 125 all within 1/2 mile
(of hardpack) it would go from 140 to 129 in a hartbeat.. never seen that before. but it ran sooooo good

I agree with you 110%. My 09 D8 just flat out goes. Makes my 08 D8 seem like a 550 fanner. Temps also climbed to 140 3 miles from the truck last time out as well. I put this down to wanting to get to the truck and home. Should have been paying closer attention and put the scratchers down. Ran 126 all day otherwise.

Update on my 08 D8

Ok. Well my dealer tore into my D8 last week, found both pistons to be scored badly on the exhaust side, and the coating was flaking off on the intake side, both pistons. He also found my pipe temp censer was shot, as was my voltage regulator. This time he ordered a new ECM as well.

One thing I noticed, but I didn't think about till today, was I have fiberglass powder from my pipe insulation, ALL OVER under my hood. Like a layer of it. So much, that after riding the sled I could wipe off my tank with my finger and there is that same dust on my tank, OUTSIDE the hood. So there is a lot of it. It didn't occur to me till today when I was in the dealer, that this could be why my motor went down. Everybody knows the air boxes have big cracks at the seams where the motor can ingest all kinds of stuff. When my dealer told me today that my sled would be a few more days because they were waiting for new reeds, it kind of clicked. The reeds where shot, (maybe not from this) But the throttle bodies where a complete mess as well. Very very dirty. I only talked to the parts guy, so I didn't ask if it was what I think it was, but I'm thinking my motor took in a bit to much fiberglass dust. My dealer has a new pipe for me to fix the dust problem. The pipe insulation was loose under the pipe heat cover, and could move around creating this dust.

So I am expecting this to be the cause. I will talk to my warranty/shop guy yet, and see what he thinks of it.

So my total new parts list is as follows:

-new cylinders
-new pistons
-new pipe
-new pipe temp censer
-new ECM
-new voltage regulator
-new reeds

I have a possible buyer, so I might not find out if the thing will be solved after this, but I think it could well have been at fault. I had the dust last year as well, but not nearly as bad. So it could also be a fault last year..... I thought since my sled problems caused such a stir in this topic I would give you all an update.

600, I doubt that the fiberglass caused the scoring at all. The v.r. is definitely leaning it out. I noticed the same issue with my pipe last year. I pulled the pipe off, got some very high temp silicone and sealed all the seams where the shell stops.

So your thinking it's a combo of the two then? Yeah could well be. I guess the silicone option would work well yeah. I would have just don't that I think, but my dealer managed to get the pipe warrantied as well, so might as well. We talked about the dust once, but he didn't say anything about possibly getting a new pipe till it was here. Sounds like Polaris is really trying for me now. And that's great. My dealer has been good as well. Wish he sold cats.

I don't know about any flaking, the gray coating is a breakin type coating on the poo pistons. I really doubt the fiberglass has caused the motor issues. I had fibers all over the motor compartment but not really any in the airbox. I just don't want that crap all over my motor, so that's why I siliconed the pipe. It only gets worse as the glass comes out and the shell gets looser and looser.

The V.R./ECU are a direct cause of the leaning/seizing. As long as it doesn't fail again and you keep a good fuel filter, I believe that the motor will be reliable.

Really? So you don't think ingesting that kind of stuff would hard the motor? I guess maybe it wouldn't. I don't really know how much junk a motor can take before it starts getting damaged. Yep I hope so. Fuel filter is new.

happy here

I have three rides in on my 09 d8 with the update and this thing realy rips, I didn't have any problems last year and extremly happy this year it's almost like a new machine. Slp single vf-3's seem to be a great combo.

Get that casing off the pipe and get it ceramic coated. Kill two birds with one stone. Drop the weight, avoid the mess, have more consistent pipe temps and less under hood heat. OK, 4 birds.
I should have some interesting measurements for you guys tomorrow. I got my 2010 cylinders a couple of days ago. And just for the heck of it I put in my 08 pistons just to visually check clearance. They fit! My 08 pistons fit better in the 2010 cylinders than in my 08. The update pistons have got to be a different part number than what the the 2010 production motors are coming with or they would never fit. Nice clearance and they didn't tip. Just thought I would pass along that interesting info.

I'm not going to spend any into it now yet. I would have to ship the pipe 10 hours away possibly farther to get it ceramic coated.

You got 2010 cylinders? Is that 08 in your sig your sled? If so you must be putting in a new 2010 case a well? I didn't think the 2010 cylinders fit the 08-09 block. That's good news though that the pistons fit. Was it possibly not the pistons fault that they were failing? Sounds to me like the cylinder is at least partly to blame. The 2010 cylinder is longer correct?

Yeah it's an 08. I didn't think they would fit either, but my dealer ensures me they do I guess I will find out this weekend. I got myself in a pickle by bumping my cylinders and letting them fall onto my shop floor. I was planning on doing Wiseco pistons (twin ring) in there anyway as I wanted to keep the stock head with the original fuel map. I suspect for 08/09 update they made larger pistons to take care of the excessive piston to cylinder clearance. For 2010 they must have tightened up the cylinders. Just visual observations I had. The lower skirt of the jugs has been reinforced on the 2010 as well. Looks like better cooling around the exhaust port too. I will get pics for everyone.

Interesting. I was told they didn't fit. But I guess you'll find out. Are you of your factory warranty? I guess if you are then a guy can do what he wants to the motor. Cool well let us know how it works out for ya.

Cylinder's are .200 longer in 2010 and will not fit earlier engines
Top case is different to to accept the 2010 longer cylinder

That's not good news. This one was definitely my fault, but now what the heck am I supposed to do? Just keep throwing more money at it? Can some machining be done if I know someone?

Can't you get the place you ordered it from get you the correct monoblock?

update is good !!

I have had my 2008 d-8 since new in 12-2007. After this latest update the thing now rips. I have had 2 rides of 40 miles each since the update. On day one it wasn't pulling rpms (7600), but ran very good. day 2 we changed out the weights from 10-62's to 10-58's (which is what Polairs recommends at 10000+ft) and it just screams (8150 consistently at high altitude in the Snowies). This is the 1st time i have ever road it in two years where my arms were tired from pinning it & having to hang on. That being said, the stock air intake is a P.O.S. it had been resealed under the hood since day one to stop all the air & snow leaks. I pulled it apart the other night and the inside of the air intake (in the hood below the headlights) was full of dust, dirt & water streaks. I can"t help but wonder if a lot of our problems is due to sucking crap into the motor. I have left off the hood air intake system & now have a K & N type filter on top of my airbox. I am going with the theory that alot of clean, but warm, air is better than dirt, or no air at all when the intakes are covered in powder. The filter I found to fit does not require any modification to the headlights to fit. Also it has been in the dealer a lot of times last winter as it never pulled the right rpms, why didn't they ever put in the correct weights?

did you find after most of your 1st tank the rpms came up? mine was the same at 7900 top then i put the slp vents in it and 2nd tank of fuel and it started to pull 8100 . by the end of tank 2 it would pull 8250 all day long ..long pulls powder, you name it..the best this sled has ever ran! i run 62s with a 62-42.46 helix and run 3500- 6500 ft

 

[HMFNW]

Rode my 09 800 with the update on 11-27-09 in about six feet of mashed potatoes and that thing f***ing ripped. All day long. Only put on about 20-30 miles cause the snow was so deep but the sled ran really strong. Just a note...I ran mine up to temp (125*-140* @ idle) and then shut it down to cool off for about an hour probably 4-5 times. On the day I rode it I let it warm up for about 10-15 minutes at idle then rode it semi easy for the first 30 minutes. After that it was on, Rode it like it was stolen.

 

[OLD GOAT]

day 2 it ran stronger with less oil in the gas. day one was at 8-10000 ft and it would only pull around 7500 (powder) to 7900 (trail). But then again the weights were changed for day 2. Day 2 was 10,000 - 11,000+ ft and it was above 8000-8150 all day long. If it holds together it think it will finally be the sled it should have been all along.

 

[thefullmonte]

Yeah, might have to. He just happened to have one of these on the shelf. I will check it on Sunday if it is going to fit or not. Once I measure everything up I will know for sure, but I think the clearances are going to be better with the newer mono block. Oh well, this is what happens sometimes.

So a month later I picked my sled back up today, they found a bad injector and my voltage regulator was junk, Polaris's check for the ECU was a f'n sniff test. When they rechecked the ohm's they found the problem. Here's the list of part's and checks done.

I picked this sled up brand new and it's never sounded as crisp or had as much throttle response as it has now. I hope it's finally right, 900 miles and 6 sets of pistons is a little much
