One cylinder Axys

[Red Mtn]

Well, they surprised the sh1t out of me! New motor is on its way from Polaris, should be here next week and possibly done for next weekend.


It looks to me like Polaris is partnered up on the extended warranties. You still go through Polaris but they have a third party that does the insuring and payouts. I was all ready to start the phone calls. Turns out that will not be necessary. My machine is getting fixed and will end up being down only a couple of weeks. Hard to complain about that...

Between stock and boosted I have seen a few PTO pistons coming apart. The mag have all looked fairly good. Wonder why the PTO is running leaner/hotter?

The tech said it got hot as well. Strange because as soon as it dropped that cylinder I stopped and pulled the plugs. The PTO side was wet and fouled, not white and melted.


No idea what caused it though, the sled was running great right up until it didn't.

The damage was already done by the time you changed the plug. The plug fouled because it no longer had enough compression to burn the fuel mixture.

From the time my sleds are brand new I keep a log for compression tests. I do the test every 250-300 miles. This gives you a heads up before you have a major failure. Eric

Great plan if you are not under warranty and do your own work. I buy new sleds with warranties so I do not have to do a compression check every 5-6 rides. How much hassle is it when compression goes down some to get them to do the right thing on warranty and go through the whole motor. It may seem a bit callus to some but I am happy the motor was completely roached and is being replaced with a fresh one. Fixing just one side and not going through the whole motor seems like a mistake that will come back to bite you. IF you can even get them to act on low compression. By the time it is low enough, something has probably come apart.


This way there is no fighting about how to do the work correctly. No pointing fingers if it goes again and a minimum of hassle for the consumer. Just hoping to do well in the Polaris engine lottery this time!

My new motor seems to have gone down as well with about 2-3 hours time on it. Was running great, taking it pretty easy like you should with a new motor just a few brief bursts. Plenty of snow for cooling, never got warm but lost 1000 rpm rather suddenly. Ran the 8 miles out on both cylinders, no codes, plugs look good, PTO side getting a little wet looking. Feels like it lost compression. I will check it tonight, dealer is closed today.


I pressed the dealer for an explanation as to why it burned down initially. The best I could get was that it was just a Polaris motor. I bet it is a bad injector leaning out that side and it has done it again. <!-- / message -->

I pressed them twice about what had caused the burn down. Of course the motor they had to diagnose on was in bad shape, probably hard to tell.


This round needs to be different, it needs to get fixed quickly, and I need something to ride next weekend. The true test for my dealer will begin today.

I am going to guess injector is failing. Seen it to many times with Pro's killing pistons.

 

[TreeThrasher]

So injectors are failing lean? And how in the heck do we stay on top of that to keep it from blowing top ends left right and center?

Is an injector failing or is the harness failing and duty cycle being shortened?

This needs sorted out

Interesting. 1300 miles on mine and about 200 boosted. Planning to put pistons in this summer. Hopefully she holds together until then!

I have felt your polaris pains! I'm one of those guys on snowbikes you made fun of last year. I got out of sleds, because of the exact thing that is happening to you. We will be riding Owl Creek Thursday. Good Luck!
