^^^ what procedure did u use to align your secondary sheaves? I took mine apart without marking them now I’m puzzles as to reinstallation

I just lined up the 2 notches on the outer sheave with the 2 rollers on the inner one. Not sure if it even matters but that way made the most sense to me.

Anybody have any thoughts on my 2019 800 high country as to why the one side melted down on me? Sled only has 175 miles on it. Trailered it 3 hours north to go riding for the first time this winter. It lives in a heated garage. It was around -27 when we unloaded. Sled idled for a VERY long time before the 'low temp' flashing light finally quit. Waited a few more minutes then slowly drove down the trail. About 1 mile later, the sled shut down completely as if I hit the kill switch. I thought maybe the magnetic tether or kill switch had an issue. Checked connections and a few things, all looked fine. Tried to start the sled and it fired up perfectly. No codes on the gauge. Proceeded another mile or two and temp was at 100F, cracked on the throttle a bit and it bogged bad. Pulled over and it was running on 1 cylinder. Towed it home and dropped it off at the dealer.

Dealer figures 100% it was an injector that failed. Should there not have been some kind of code that would signal this?? I'm fortunate that they ordered a new crate motor and putting in new injectors but I really fear its something else that caused this failure. I haven't driven the sled hard and always warm it up well and take it easy for the first 5 minutes of riding. My warranty will end at the end of February and I'm having a hard time trusting this sled going forward. Thanks for any input

Did this sled get the water pump update done? The reason I ask is my 2019 alpha did the exact same thing with 40 miles on it there was a water pump impeller update and mine was driven by original owner before the updated and fried the same cylinder cat put a complete new motor and injectors all go now

I will check with my dealer, thanks for the heads up! I just picked up the sled on Feb 28 of 2019 so I'm guessing it would have had updates done before I got it. I will certainly ask today. Thanks again

Are they replacing the complete engine? I would hope so. If the're just doing the top end I would be concerned about aluminum contamination throughout the bottom end. It won't do well for future longevity. Unload it.

Dumb question but is the only serial numbers listed that are affected by the bulletin?
My serial number is between a couple on the attached sheet.

Thanks in advance
Mine wasn't on there, but was affected.

complete crate engine, and new injectors

Doesn’t a new crate motor have a year warranty on it if dealer installed ?
Get it back and run it .

I thought there would be some kind of additional warranty for the crate motor but I was told yesterday by dealer that warranty on the new motor is 30 days from the claim or end of factory warranty, which for me is the end of February. I''m only going to have probably a couple days before the end of the month to ride it which sucks. Going to price out extended warranty but I've heard mixed reviews on how good those policy's are

How do you get the exhaust bog to go away on a 2018 mountain cat 800? Already sealed the intake.

Johnny, did you ever get your sled running 100% and the bog gone? What all did you do? My 18 has a slight bog and I have sealed the intake, I think it is exhaust related as well, the snow was too deep for it to breathe unless you were right to the bar all the time. I think a snow deflection guard could be a solution, wondering what you did for one? Thanks!

I had some bogging issues in really deep snow last year. This year I added some frogskinz to the airbox behind the bumper and was in some really deep downhills on Saturday with no bogging. Need a super deep day to tell for sure though.

Are those the circle ones hurkot had posted a while back in this thread? I think I'll give these a go? My bog was bad enough to get me stuck on sunday twice, was hard enough to get around without bogging lol

There is one that goes under the hood and when the suction gets high enough it opens to grab air from under the hood, I forget who makes it.

Sounds like an SLP powder valve.
That's the one.

I have also seen guys put frog skinz in the shock towers and into the air box.

I found that if the intake get burried and it bogs it means your intake nose seal is leaking under suction. Vasoline the **** outta that seal.
