Spark plugs

[Timbre]

In the latest Muskoka video, his 9r broke like 6 spark plugs in the course of 2 days of riding. Guys, that's f'ing ridiculous!

I only saw 2 plugs blown for the 2 rides he posted, but could be wrong.
One thing i noticed was that he was riding in super deep powder, and getting a pretty good bog when his vents were covered in snow.
Then shortly after that, the plugs failed.
Makes me wonder if the lack of venting contributed to the issue somehow.
Probably just coincidental, but food for thought . .

But ya . . . not good at all to keep riding it until he figures out what is causing this!

I was thinking of Snowchecking a 9R. All of these broken clutches & plugs from detonation are a major bummer. If I owned one I would definitely mix a little race fuel in it . The next problem will be the piston ring locator pins falling out. Hopefully a new map can fix it if there's a lean spot.

Ugh, I just had that happen on my wife's 2018 Ayxs 800 (locator pin falling out ). $2,750 later ....

I experienced this today. I’m just south of Revy, snow is insane right now. I had a really bad bog with my boost in the deep snow then popped a spark plug shortly afterwards. Might be a connection. I was more diligent whipping my vents and was good for the rest of the day.

Muskoka posted in the comments that he had been though 5 plugs on the 9r as of last week, could be more now

Last ride he did not break a plug with 94 octane fuel from Chevron. He did have a bog but it appeared to clear as he wiped the vents. Are any of you guys that ride above 6000 ft breaking plugs on the 9R?

I have just over 300 miles on my 9R all between 8,500- 10,000' elevation and have had no issues, no plug failures, no p-22 failures, no bog issues, no track issues, no 7S gauge issues. the only thing is the throttle block has to go, it does ice up quickly in deep powder, probably put a TKI one on. So far its been a great sled, time will tell I guess.

No way. This is not possible. The forum will not believe these lies!

In break in it will run more rich so your experience is not as much value to determine if the map is too lean.

I was done with break in at 211 miles, just giving my experience with my sled that I have had no issues.

I separated mag side plug with only 130km on my boost.

 

[saskrenegade]

The plugs that were separating were also on very deep days where the exhaust was plugging off and bogging bad?‍

Don't buy exhaust plugging breaks plugs for a minute. Det

Muskoka and a buddy took out clutches yesterday.

 

[kittykitty_900]

It was hard to tell by his Insta story but it looked like 3 of them?

I hope this did happen as Polaris will likely hear about it and hopefully take this seriously. If they don't address this at snowcheck I might ride my 850 Khaos for another season.

[koolaid]

That would mean both his new sleds are down for the count. No videos then?

 

[kittykitty_900]

Not sure if it was his sled or not

E85 is generally 105-108 octane. Certainly not going to hurt on that side.

The ethanol tune is for 87 or 89.

It's a widespread myth that ethanol causes detonation. Only in the sled industry. Every other form of motorsport has realized it's just octane booster that requires extra fuel to account for the lower energy density. Detonation can be caused by the lean condition just as much as a lack of octane.

I support the filling the truck first though. I try and only go to the stations where ethanol free 91 is on a separate handle and hose. I do the same on a mixed pump though, fill the truck first and then the sled.


The biggest reason to avoid ethanol is the corrosion it causes by being hydroscopic. That is the killer.



Of course, it's all a moot point when the gas station gets their tanks filled with the wrong fuel (which does happen, especially when everything is covered in ice and the trucker just wants to dump and run while he can't read the covers).

Not saying the person driving the fuel truck doesn’t make mistakes or have a bad day sometimes but if you think a driver routinely dumps the wrong fuel in the wrong tank and gets away with it without consequence from the customer/station or their boss, you are very sadly mistaken. It’s a big deal trust me.

Our local guy has put gas in the diesel 3 times over the last 10 or so year. No idea how he still has a job.
