Remember the filter outerwear sock for Cold Air Intake !!!!

Just came back from QC trip. Fast running excellent trails in the Lanaudierre Region ( best IMO). Buddy was running his AC 9000 sled middle of the pack as usual, until he gets his groove on and takes off past everyone. Tuned sled. Has run it for three years with zero issues. Lots of snow dust all day. Later in the day blew past everyone on a long opening I heard a back fire and poof two cylinders. After opening the the cowl snow dust all over uncovered K&N filter. Sucked the snow dust in and well you know. Dealer does all of his work so....It is why I do my own service for most things. Peace of mind. Just nuts how a simple oversight can wreck things. If running CAI cover the filter.

So did he actually lose a cylinder?
Whos tune?
No knock lights?
Closed loop?

LOL !

Inquiring minds need to know.

How did it go poof from plugging up the filter? Plugging the filter with snow would make it breathe less and make the A/F richer. I know that would not take out two cylinders. Unless the filter failed completely and let the snow thru into the intake, then I could a failure of snow taking out cylinders. Otherwise I don't see snow getting thru a K&N filer enough to do a bit of damage to the cylinders. It would take a lot of it in a big gulp to hurt anything. People run gallons of water/meth injection on turbo vehicles all day long and no damage comes from it. This doesn't add up.

Yes. Lost cylinder. Not tunes fault. I have the exact same tune for four years. TD max 17. Sled had 5,000 mile son it tuned. Mine has over 7,000. No lights. No closed loop. 94 octane. 3 inch exhaust.

Let me guess. PEFI tuned????

I see your point. All we could figure was he was riding up someones a#&se all day and when he clamped it to bars its sucked it through the filter. My other buddy is a top notch mechanic and that was his best determination. BIG back fire when he hit it. Took off five miles down the trail before it happened.

 

[Bigblue1]

Lost one cylinder. Temp was 167-172 all day.

I always run hiigh test with an octane booster just in case. Not sure he did, but he never has all these years with no issues. Hard rider.

Pull your side panels off and stick your hand above the factory vents up front. Their is a big gap right there on both sides.
This area needs to be sealed off with some foam.

If I ride behind someone like that and go the pass them I can feel my belt slip when I hit the throttle from the snow. I also have an outerwear filter over my k&n filter.

Can't see taking down a cylinder from snow.
He must have had other issues.

Good to know. Thanks.

Highly doubt it was snow dust ingestion. Some thing else happened here

 

[Bigblue1]

Just took to dealer. I’ll let everyone know when I hear back. Would be good know what it is to be proactive at the very least.

Fuel octane has been all over the place lately even in Canada. My buddy with a Poo 850 just got back from Quebec and said his DET light was going off like crazy with 91 octane fill ups. Changed it to ethanol mode and no more problems. Lake riding around here with our local high volume station 91 octane and 2 oz of Boostane not a hint of DET in the non ethanol mode. I am thinking octane booster is going to be our friend with the crappy fuel around. Probably going to get worse the way things are going.

 

[Bigblue1]

It’s why I add a booster with every fuel up. Can’t see why his light didn’t come on or why ecu wouldn’t pull timing though.
