800 Warranty w/ Mods???

[IDAHO HOT SHOT]

Im running SLP twins and Carl's head. Im just curious what every one else is being told to do with this modded head head because Polaris wants the OEM parts back when the warranty work is done or they wont re-imberse the dealer for the job. Im bummed that I just got my head done and My ECU re-flashed and I might have to pay to do it again. Your thoughts Please...

 

[hilinerider]

you can put your stock head and pipe on and take it in, get a spare ecu and keep yours if you want to put the twins back on after they are done with it

The stock head is the one that is milled

 

[Jkinzer]

if you are running twins you do not want to do the update anyways. slp twins will not work with the new polaris head. for customers that are wanting to do this update kit and still run twins, slp is now selling a billet head that puts it back to the 09 specs pretty much which would really defeat the purpose of doing the update. polaris will want the stock head back in stock shape or the warranty will be rejected. i think your better off to run it the way it is or just buy a pair of the new dual ring pistons

This recall is going to be a strange deal with mods. Am I right that most people think that the recall is just reduced compression, new fuel map, and duel ring pistons? I know there's guys out there that ran a fuel box and plenty of octane and still had seizing issues. No one I know rides a stock sled and I think everyone is going to take and leave parts of the recall. Turbo guys may take all of it but guys running aftermarket pipes may only take the pistons and the re flash. Kinzer I remember you saying you were thinking about leaving your sled the way it is with your turbo. With all the new Boondocker bells and whistles have you reconsidered?

I thought the dome shape was different on the new pistons so we had to use the new head???? I didnt think we could use the new pistons with the old head???????? hopefully this new head and piston wont flake out my fuel settings on boost????if the SLP twins now dont work some thing has changed debating on getting my ECU reflashed also?? My dealed says he has plenty of new take out single ring pistons now,,,, mabe I should just stay with what I have since it works great?????

The problem is: Polaris, as I understand, wants ALL of the parts back. According to SLP, the piston rings were most of the problem . Apparently, the rings are crutial to heat transfer. A dual ring piston, according to them, will help substancially to cool the motor down???? For hells sake, how much are new pistons?

"I thought the dome shape was different on the new pistons so we had to use the new head???? I didnt think we could use the new pistons with the old head????????"

That makes sense. Our dealer said the new head is pretty radical. I guess SLP will have to do a re flash too. My one buddy has a Fastrax head on his. I wonder if they'll be able to mill it to fit the new pistons and accomplish the same compression?

That SLP theory makes the most sense yet.

It's nice to know that I am not the only one who has nothing better to do than dork around on the computer instead of working. Im really confused now. From what I heard, I think SLP told me this but I cant remember, you should be able to use the 08-09 head w/ the new pistons. Dont Quote me apparently I don't know what the hell Im talking about. Surely F-Bomb will have an opinion on this, Rob...

I.H.S.
Is your twin setup the Carls "race gas" twins setup?

Call up Carls or put out a WTB in the Swapmeet.... buy a good used stock head... With all the custom heads for the mods and the turbos out there.... you should be able to find a good stock one. Return the stock head.

Call Jack Struthers directly at Carls and ask him what they plan to do with the 2010 800's?? Do they have any plans for the twin pipe mod head on the 2010 sleds?

The only thing you might be keeping is the pistons...

Here is the Rub... no matter what you do.... if you squeek a single ring piston... THE ONLY piston avavailable for the 800CFi now is the 2 ring, 2010 style piston... so, IMO, you should be prepared to be able to run this new piston rather than scrambling mid season.

Jack will be able to give you the straight story on what you need to get.
How far are you from Carls to have them do the work?

Pistons are kind of pricey ... I believe around $250 for the pair.

The person on the forums here to ask about the dome shape and deck height, IMO, would be Super Dave3.

 

[mountainhorse]

As far as the recall goes... it is an "All or Nothing" deal...you wont be able to just get the pistons or the pistons/head or just the reflash.

Polaris wants the problem fixed... Picking and choosing won't be an option

Polaris Industries is not concerned with mod sleds because, according to your warranty, they are not covered anyway.
Specifically, your twin pipes and head mod void the warranty.

The dealers, even the good ones are going to be leary about doing any mod sled warranty work on your engines... Polaris is really cracking down on them with some pretty big penalties for servicing non warranty items. Last season they had field reps visiting the shops, I'm sure this will be the case again this year.

For example, if a visiting Polaris service rep were to visit a Polaris shop, and they saw the mechanic was installing an update kit in a customers sled with a turbo or other heavy mods, would they decline coverage on the sled?

Carls Cycle has designed a piston they r using in their 800 cfi turbo sleds with the 2010 head and reflash.

What are the details on that piston?

1 or 2 ring?
Forged or Cast?
Lower compression?
Special Dome?
Special skirt?

Good to see Jack finally jumping into the Turbo boat with both feet!!

I just spoke w/ SLP. The word on the street is this: Run the update kit w/ their new domes and fuel map. The new SLP domes are supposed to have the compression of the 09 head and 3-4 more HP. So essentially, the only thing that you need from Polaris is the double ringers.

 

[trench]

The information I got from SLP is if you are running there performance pkge.

Which has there porting , milled head(old head) ,y-pipe mod, airbox mod and there re-flash .

Do not use the new head from the upgrade kit, but use the new double ring pistons only.
The new head will not perform well with there porting , compression is not matched to there porting.
I'm running the slp performance pkge and my 800 Dragon is aready done this way
Running the new dbl. ringers in the original milled head.

I hope they gave me the correct information.

I was told the new head will work great for all turbo's though.

I spoke to them also, and for high elevations w/ SLP single, they are telling us to run the SLP head. Apparently the new polaris head has compression that is too low for high altitude when running the single. (to produce the same results as 08-09). FWIW.

piston interchange

"I thought the dome shape was different on the new pistons so we had to use the new head???? I didnt think we could use the new pistons with the old head????????"

The new pistons have a longer skirt and thicker top ring, but they still interchange with the 08 and 09 pistons.

Anyone know if the new SLP head has the funky cone-shaped dome and projected plug like the new Polaris, or is it the old round shape?

 

[skibreeze]

I'm wondering what is up with the heads, as they had a different one installed part way thru last season during one of my many piston replacements.

SLP head is the old style round shape and gets the compression ratio back up to 13.5:1. They advertise a 3 hp gain over the OLD stock head, which was also 13.5:1. The new cone shaped stock head is supposedly putting out a 11.5:1 ratio according to local SLP rep. The gain w/ SLP over the new head could be very significant for high altitude.
