2011 assault burndown

[Deucer]

Talked to SLP today. Brought up the adding oil and possibility of leaning out the motor. Well if that is true why does the dealer add 2 oz of oil per gallon of fuel to break in the motor? :-0 Add 1 oz per gallon and you will have no problems at all with leaning out the motor and it just might be the band-aid needed for this motor.

Yep, Me to. These pro's just sip oil. I always put a little "Break In" oil in the gas. If it is good for break in, it couldn't hurt for a broken in engine. Maybe save an engine with an air bubble in the line or a rubbing oil line (factory recall update)that may go unnoticed while on a good ride.

During break-in you aren't running it as hard, though, which is when you are going to burn down. Also I'm not sure, do these sleds change their fuel mapping after a break-in time is over or not? That could be a factor if so.

You're probably right, though, a small amount of oil isn't going to hurt it.

 

[blackie205]

70% of all burn downs is caused by bad fuel or cold seizure in my area,the other 30 percent is crank or piston skirt failure and so on ,these motors have 2000 + miles the other 70 percent all under 2000 miles,imo adding oil to tank is great even a few onces to a tank will help any motor,i also tell everyone to run prem fuel if possible and dont ever run coop fuel it is very poor and 50 percent of those 70 percent r due to coop fuel (atleast in my area)warm up for min 2 min + also i use the 1/2 throttle rule one half field no more then 1/2 throttle or if in mountains min-2 mins warm up and 2 mins of nothing more then 1/2 throttle if a guy remembers these few things u will have a much hapier and longer lasting motor imo this is just what has always worked for our group

Went riding yesterday, sled started bogging at 6-7000 rpm but no det light came on and still was gettin 8200 rpm. As we got to around 11k my sled totally bogged out and died. I started it( 11 pro with 1800 miles) and it idled really ruff and low rpm.Looked at the crank while it was running and my cluth was spinning in a off balance rotation.So i hauled *** back to the truck and it sounded like a 4 sroke and shook like crack whore. Not sure but seems like the crank is ready to let loose,will take it to dealer tomarrow.

Huh? I think the crank is either broken or not, nothing in between with that much vibration. Seems like some on here are complaining of motor mounts or plate mounts causing some of that type of vibration at the clutches that you're talking about. Hope you get it figured out and it's an easy fix. Good luck!

 

[gmustangt]

how much oil are people adding to gas to premix? i have almost 400 miles on my 12 and this weekend decided i would try and add some oil to the gas. don't want to add to much but don't want to add to little.

100:1, per recomendation from indy dan.

hey wait were you riding my sled?....my 11 assault lost the crank this weekend...872 miles 100% stock, best sled i've owned to date.

After removing the primary bolt at the dealer, the crank stub was sheared off.


Meanwhile the best Polaris dealer in Glenwood Springs Colorado, gave me a brand new 2012 demo till everything's fixed....



ps...since my pro never use much oil 40-45:1 on ave, i prefer to add 1oz per gal when filling up...cheap insurance, imo.
helps with cold starts, and when she idling upside in a tree-well...

You better pull that sled apart and get them bubbles out or your going to wipe out that engine. LOL just a poke at the guys that are worried about air bubbles just curious if they take the time to get them out after they roll there sled. Somebody needs to make it a sticky about the airbubbles i get sick of people repeating it

 

[SLDHVN]

a good way to get oil lines clear of air is to let the sled idle and use a long screw driver to hold the oil pump wide open for a bit once she starts smoking like hell its probably purged all of the air

 

[bsietsema]

I did, no worries. As far as the belt, yes I did 2 days before, but I was fully aware it was ready at anytime. What's your thought to this?

I hope you realize I was taking a shot at Murph.
I would like to know also as I have two 2011 Pro's.
One rumor that came right from a dealer is that the cylinder skirt have been breaking at around 1500 miles. I agree on your assessments on the sleds in years past. But getting back to your sled, I had the same thing happen to my 2007 600, twice. The dealer said it was an oil issue. After the second time the dealer tested the oil pump. That turned out to be working properly but they replaced it anyway and I had no problems after that. You didn't happen to blow a belt previously did you?

I follow your line of thinking with the over rev. Eliminating the pull or load from the motor as the belt comes apart seems in my mind to be a relief. But I am no engineer. WEIGHTS I made a mistake I was running 10-60. My buddy was attempting to shave 62's down to 58-59 for his '10 RMK. Short notice trip and we couldn't find a dealership with parts. The 62 was simply stuck in my head.

In the Shop Now

The hardest part for me the last 3 days has been not tearing into the sled myself. I'm a month out of warranty from the december of 2010 when I purchased my sled until december of 2011 when the manufacturers warranty ran out...the good news being that I have three different dealers that are foaming at the mouth to work on my sled because the "haven't" seen a newer liberty(2011-current) have problems yet. At least this is what the dealers are telling me???don't know if I can believe them. Nonetheless I dropped the 2011 800Pro off last night and will be getting an update very soon hopefully as to what may have caused this seizure.
I've been getting grief from Artic Cat owners for 6 years now and was stubborn enough to go ahead and buy the 2011 RMK...hopeing polaris had figured it all out well see.
I've also been talking to some boys out of West Yellowstone and Island Park about the "Durability Kit" that some of the rental places are going to so they can get some life out of their sleds. Anyways I'm hearing a lot of conflicting opinions and no one wants to step up to the plate for Polaris and admit they have a problem with their specifications. Love my sled don't want to give it up for a kitty Cat.

The 62 was simply stuck in my head.

From the start I didn't buy into the idea that the weights were the problem. I made that mistake out in Cooke (8,000' to 10,000') a few years back running one 09 D8 with 10-60s and another 09 D8 with 10-62s. The one with the 10-62s would be hitting around 7800-7850 RPM on a good day. Did change them out to 10-60s and that made one heck of a difference. I will say though, that since I got the 2011 Pro I ALWAYS WATCH MY TEMP more than anything else.

Was the blown belt a stock belt???

Keep us posted! I would like to know what the heck happened.

 

[Big D rmk700]

I know most guy's renting sleds in west yellowstone and there "durability kits" would be add fuel and oil daily and run the sh*t out of them!!!! very few had problems last year and have not heard anything major this year!!! We have 2-11 and 3-12 in our group with between 700 to 2100 miles and no problems to date!! I have a 11 2100 miles and have had new injectors installed this fall only thing I have done!!!Oh a couple of primary springs broke!!

 

[Old Scud-doo]

The durability kit? Is that the water re-routing thing to prevent cold shots after sitting a few minutes?

I have only this to say, if it's truely a cold shot problem the rings/pistons/cylinders would look crappy all the way around, not just where the injectors fire. I think a lot of people keep pointing to cold shots without digging a little deeper into the real reason behind it. I am not saying Murph or anyone else doesn't know what they are talking about. I am saying I know that my set of rings are trashed only in one spot, not all the way around.

 

[bsietsema]

Yes stock belt. I put that through the ringer. @ 140$ a piece i figured i wasnt going to win any awards for first blown. I will let you know what the largest polaris dealer in world says tommarrow. Mies Outland, watkins,mn

[rotax]

Another dead '11 Pro

Also have a dead 11 Pro after, ~12-1300 miles.
Stock.

Dropped it off at the dealer today.

It used very little oil...which I'm afraid is actually the cause.
Going to ask that they turn up the oiler when they have it tore apart.
Sick of 2 strokes lasting for 1 year/1000 miles and dying.

Always warmed up to at least 115* before even leaving, in the morning, and after every stop.
Had the typical 125-130 temps.
On the very rare occasions when it'd go over ~155-160 (while using scratchers) on the very frozen trails/lakes I'd stop and pack snow on the running boards and tunnel.

Love this sled otherwise, really would rather not go back to a 4 stroke.. Ugh.


Anyway..doesn't look like any of us are at all alone with these dead engines...something is wrong, and I want more than just a "replace the engine" fix and have it fail in another thousand miles.

pro issues

I have a 2011 pro and love every minute riding it at high elevations , Right now it is at HM Turbos getting Shane's 25 HP mod . I am extremely confident shane has done his research and am looking forward to riding Lolo,Mt feb 11th . If you have any questions Shane can answer them im sure , the mod he is doing seems to address compression,oil usage , clutching, fuel mapping and traction , so far I would recomend anyone with motor issues call shane . Ill let you know how my sled performs after the 11th
