what is goin on?

--How would a person self-inflict flaking rings, a blown out connecting rod bearing, or and engine that is picky about fuel?
 
it feels like i flashed back to 2009-10, up til a month ago 99% of post on here were how good the pro is and polaris finally got their game togeather. now 99% of the post are trouble under the hood mechanical and electrical...major problems all over the board..........just sayin

Don't pay any attention to those posts as they are being made by jealous Skidoo riders. :face-icon-small-ton
 
--How would a person self-inflict flaking rings, a blown out connecting rod bearing, or and engine that is picky about fuel?

like I said 50%. Some failure are going to occur. Unfortunatly alot of us are going to have to blend our fuel to get anything decent! Especially you guys in CO. from what I understand its now a crime to sell non-crap fuel in CO.
 
Polaris BS

I think the lack of bad news first part of the season was due to lack of snow and to many of these machines sitting waiting for enough snow to ride them, I have a 12 Assaust just over 400 miles on it, blew a connecting rod and granaded the engine, catastrophic engine failure, now its been at the dealer going on 2 weeks and there telling me polaris is still deciding if there going to warantee it. I talked to them yesterday to tell them to get the dam thing fixed and they told me I would be paying for the parts up front untill polaris decided if/ how they are going to fix it, if I wanted it done now. Bought it @ Christmas, 6 rides, only polaris VES gold oil, only good fuel from trusted and reliable gas station. now I'm out 300 to get it off the P/L ROW I was checking when it blew, out 4 $150 sled dayrates not finishing check those P/L's, and all my local snow is melting, days off booked for sled trip, got to sit @ home, wanted polaris reps # form dealer, they would not release it to me. Can anyone out there help me. The only icing on the cake is that only 2 riding partners came over to the poo side this year, and that in the last week 5 cat and scud buddies decided that this was not the way to go after hearing about my ordeal of trying to get back on the snow. So @ least for the grief the giving me their out $ 70,000 in lost sales for next year, and hopefully more by the time I'm done passing on my story to everyone I see on every trail every cabin every medow and every mountainside.( P.S. I no there built for HP and not longjevity, this is why I buy a new machine as soon as warantee is ran out)

This is not typical and you really have to look at how you warm your sled up and do your homework before you take off and ride. I am not saying it is your fault, but something just doesnt sound right about your story. 2 weeks and Polaris hasnt made a decision if they are going to cover your burned down motor:face-icon-small-con They must have a reason for hesitating, especially being a brand new sled. I take each one of these stories with a grain of salt.
 
I can apreciate taking anything said on a form with a grain of salt, your comment is about the same impression I get from polaris. But I can assure you the machine was properly warmed up. I have been doing this a little while, first machine 650RXL, then 600 summit, then 800 summit, then 800HO summit, then 1000 summit, now this assault. Fact of the matter is I thought having a temp gauge to confim engine is properly warmed up was the greatest thing since sliced bread. P.S just talked to a cat buddy that just SC a XM summit, and a scud buddy that just SC a new proclimb, both were looking @ pros. prior to this abortion of an operation I'm being currently put threw

Polaris may have sold alot of rmk:s since 2011 but it's nothing what they could have sold if people only trusted their 800 motor, I'd love to buy one but when even the pooguys I talk to say that they would'nt ride it out of warranty it makes me hesitate. We can only get 2 year warranty over here and I can't buy a new sled that often.
 
My understanding of what is wrong with the Pro 800 CFI is Polaris has leaned out the mid range to meet emissions. The pistons swell and squeak to the cylinders. So Polaris has been making there piston clearance more and more every year to stop it from seizing. So with extra clearance the skirts can rattle and break off.

So getting a fuel controller to add fuel in the mid range and take fuel away on the top to make more power. The kit I am going to buy you get better designed pistons, a spacer to change port timing, and a head. I am also going with a DynoJet PCV fuel controller to add fuel in the mid range, and a thermostat to prevent your cylinders from getting blasted with cold coolant when you start. For $1200 it will save you a ton of grief and then the motor wakes up and totally rips..

..and all the Dragon owner that had problems caused them (the problems) themselves too? Not buying it. Same primary motor design with the difference being pretty much the change from 4 injectors to 2 injectors.

I had a 09 800 for one season and never had a problem, but that doesn't mean they didn't have problems.

Yes, problems become apparent on these forums more so than word of mouth. I guess other than the Dragons, has anyone checked the Ski-doo or Cat forums to see if they have as many engine related issues? I still think Polaris has more than their fair/marketshare of such issues.

Seriously, there seems to be a lot of "my sled died" or "My sled is not running right" threads right now. More than I saw when I was checking out the XP or Proclimb thread. Lots of ticked off people on belt eating sleds but nothing like what I see here.

The fix is there, if people dont want to take it upon themselves to bullit proof ur engine then IMHO you must baby the factory motor.
 
I know what your saying, people talk about the bad more than the good, and i know there are a lot of pros out there, it just seems that all of a sudden the dragon 1200 - 2500 mile problems are right back again. the individual problems i don't mind as much as the " all 5 in our group" problems. sorry guys just a little rant/worry... i just hate when a new sled goes down and you got to sit in the cabin for the rest of the trip.
talk to snowmobiler, im sure he can help you with a new t-motion ski-doo!
 
I came from a Yamaha Nytro MTX and GF had a Phazer MTX-- I was paranoid about buying a two stroke-- my first two stroke anything, ever. We bought two 2011 Pro RMKs. I have a 2011 with 2500+ mountain miles on it (I live at 7000' -and the GF hates trails more than me). Girlfriend has a 2011 with 1500 mountain miles on it. We had so few problems, we snow checked a 2012 for a spare.

Here's my take on this-- keep in mind I'm throwing myself under the bus with this.

I'm ready for the flaming to come.

I think more people need to do the same and own up to their mistakes, assumptions, and (sometimes) lack of mechanical abilities also.

Here is my story: told through a SnoWest thread I started here:
http://www.snowestonline.com/forum/showthread.php?t=304835

Just got back from 4 days riding in Alpine, WY.

Sled ran great put on just over 200 miles.

Sled now has 500 miles.

Got back home to Tahoe and went for a ride.

Sled had a problem. Would occasionally cut out, and then run and then cut out. Activated DET sensor a couple of times ( first time ever for me out of three Pros). Running ethanol resistor. 10-62 clutching at 6500 feet.


First thought ignition. Checked plugs, coil leads, caps, etc. Seemed fine.

Seemed to be getting progressively worse as the day wore on. Stab the throttle from stand still and the sled would bog, then go. TSS switch is over ridden with tape, has been since 35 miles.

Thought fuel. Heard a whining noise from fuel tank and thought maybe the tank vent was clogged. Opened cap when sled was running to see if the noise would go away when the cap and possible vacuum was removed. No rush of air when cap was removed BUT pump was making a distinctive whining sound-- sounded almost like a hamster wheel.

Thinking this is my culprit-- it would explain DET light if the engine was starving for fuel. It explains the bog. The whining sound is intermittent, as is the cut out. Thinking now the pump is not receiving 16 volts, or the signal, or the pump itself is failing. The whining sound makes me think it is the pump itself.

Anyone experienced with a Polaris fuel pump failure on a Pro or anything else that uses the same pump? Will the pump whine if it is receiving less than 16 volts?

Will swap out entire tank / pump assembly from my 2011 to see if it rectifies the situation. Isolate it to see if it the pump itself or the signal and/ or voltage to the pump.

Any input appreciated.....

After some input from other SnoWesters....

Rubber strap wrench worked great. Re used rubber PFA gasket.

Pick up filters looked good, still white no black goo or stains.

External filter, blow through test seemed fine no restriction.

Pump volume seemed good (still need to do pressure test).

Pulled powervalves, not too carbonized but they did seem a little sticky--reading up on DET code, powervalves could cause DET, and when it sounded like I was dropping a cylinder it could be that the powervalve was sticking.

Anyone else notice the difference between 2011 and 2012 powervalve guillotines?

Will button it back up, fire it up, check fuel pressure (idle and running) and solenoid.

Keep everyone posted

What I found.

Cleaned powervalves.

Checked fuel pressure.

Drained gas tank completely and changed gas.

Rode 44 miles today. Tried to get the sled to fail...it didn't. Think it's fixed.

Hate to admit that it may have been nothing more than the exhaust valves. Strange how we sometimes don't notice normal sounds (fuel pump) until the sled starts misbehaving.

Worse, I have to admit that I suffered from SW forum induced paranoia. Thinking I had some major issue and it was either bad gas or sticking exhaust valves.

Oh well, live and learn. Just stoked its remedied. AND happy I didn't take it to a new dealer (mine just closed) and their first experience with me is I'm complaining about a running issue that was pure owner error!




For sure this is not the case with all issues/ problems reported. I know many of you have more mechanical ability/ expertise than me.

But I also know some of you have no business with a wrench in your hand.....

All sled manufacturers have problems. Some more than others. If you want bulletproof, ride a Japanese four stroke. We ARE spending lots of money to enjoy this sport. It's worse when we spend money, time, effort for nothing because something breaks. We are so frustrated that we just spent good money and didn't get to enjoy it we fire up the computer....and start flaming EVERYTHING, because we are understandably pissed off.

I love my Pro. I recommend the Pro. I'm not a Poo faithful. I just understand that things happen when you squeeze 150+ hp out of 800cc. I do my maintenance, clean my clutches, turned up my oiler, and always let my sled warm up before hammering it. Will this guarantee I will have no problems? No. But I hope it minimizes my risk. For the inevitable, we have warranty....and a spare sled.

Flame on.....
 
Have to say that I don't do my own wrenching. Not worth screwing something up. Always have dealer do any service needed. They turned up my pump. I replace spark plugs and that's about it. Maybe plug wires to MSD wires but I will not screw with the oil or fuel systems. Add oil to tank and let the guys that do it for a living turn the wrenches.

You know Murph most of us (non mechanical folk) understand that using crappy fuel and oil gums up your power valves, but the best part of your story is you believe that this is the problem with the CFI 800. Hey everyone Murph has the answer, Thanks murph.

Based your response, I guess I need to explain myself. I am not claiming to "know the answer".

I am not discounting that some sleds have problems.

I am not pronouncing that the Poo motor is perfect while wearing Polaris blinders.

My point was in regards to the original poster's question about why all the negative stories recently in the Pro forum. I used my personal story as an anecdote as to what can happen after reading too many Snowest posts and forgetting the age old rule.....Keep It Simple Stupid. I heard trampling hooves and thought, "Zebras!"

I was not trying to suggest that every person's issue reported on this site was unfounded and operator error.

I WAS trying to expose the fact that many reported "problems" are operator errors-- mine included. How many times have we read about an engine "cut out" that was solved by adding more primary weight? Or adjusting the throttle cable free play?

The only "answer" I was trying to promote was that we need to be more responsible in regards to how our sleds run and how we diagnose problems.

Again, in reference to the OP, I don't think anything is "going on" and all the Pro's are grenading. Some are definitely failing, some may simply need to have fuel filters cleaned, exhaust valves cleaned, TPS adjusted, throttle cables adjusted, motor mounts re torqued, head bolts re torqued, etc, etc, etc. Especially now that they have more miles on them.

But thanks for making me laugh with your last comment, "Hey everyone Murph has the answer, Thanks murph" -- your passive aggressiveness was almost palpable.

Thanks Murph, good points to consider! Hey Kopaka, what do you actually have to add to this thread? Just to post what seems sarcastic replys takes away from anything helpfull/knowledgeable you might have to say. Staying on topic adding any information that might be helpfull will go along way in the old Snowest community.:face-icon-small-coo
