Am I expecting too much?

Loaded sled tonight… fouled a plug. Put it in reverse at 83 degrees, died a few seconds after it restarted. Does the 850 tend to foul plugs when the sled is shut off and then restarted before getting up over 100 degrees or so?

Seems like my 2019 850 did that, same with this sled.

Yes, but not exclusively. Track which cylinders foul for a pattern. I have been finding a few defective coil packs helping cause this issue as well.

Test them all you want, you’ll never be able to duplicate the intermittent drop outs of spark.

Btw, Do you need a go fund me for some plugs? I can help if you do.

I haven’t changed a spark plug since 2017 when I went back to Doo.
 
i changed my boost to the br9eya and no more plug fouling. now polaris recommends going to a 8 not sure how with fuel injection they can be so far off on the mixture. WTF polaris do better
 
I haven't bought a brand new sled since about 2000 when they Costo'ized their business model and made it impossible for the small "service oriented" mom and pop dealers to meet their sales quotas. I knew that was the end of decent service and dealers that truly cared about their customers. All my sleds since have been made from scratch from the best stock and aftermarket parts I can source, and I still typically do my own modifications on every single one to meet my quality, strength, and performance criteria.

Sorry the big box dealers are screwing you over, but I saw it coming nearly three decades ago. There is no service anymore (anywhere), and there are so many loopholes in warranty and insurance contracts they are worthless and a giant waste of money as well. Pick what you want. Buy it outright, maintain it yourself. Ride happy! FiretrUCK the S(d)dealers!
 
MY25 Patriot engines come with NGK BPR8ES spark plugs with solid caps. They are also recommended for earlier Patriot engines.
 
Story time-

It's mid January of 2023... I decide I would like to find a new Boost. I locate one about 100 miles away on January 26th and purchase it. I paid MSRP. A week or two later head 14hrs west to ride. Immediately I notice a hand and foot numbing vibration. I try to troubleshoot and think maybe I have a track/driver issue. I replaced the 2.75 with a 300LX after picking up. No luck figuring it out. Random bogs. Blow a belt in 12 miles. Sled went in the trailer with 20 miles and I rode another sled the rest of the trip. I get home, tear into it and find chewed up rollers in the secondary. I order and replace rather than taking it to the dealer 100 miles away. Still shaking. I call the dealer, they get me an appointment in about a week. When I drop the sled off I tell the service guy to make sure the tech RIDES THE SLED. It is a very obvious vibration/shake. A few days later they call, "your sled is done, the secondary was out of alignment". I had aligned with the TRS bar before ever riding... and I know his specs are slightly different from Polaris. I had removed or added shims... so I had a suspicion it was not fixed. When I picked the sled up I asked "Did the tech ride it?" Service guys goes "Uhhhhh.... he knows those machines really well" .... that's a no. I take the sled home anyway. Ride it about 50 yds and realize it's no better. I do a few laps around the yard and the clutches are HOT. Still thinking I maybe have issues I swap to a different track and drivers. Still shaking. Ok, it has to be a clutch issue. I pull the secondary apart and get another set of eyes. There is NO bushing in the movable shive on the secondary. There was NO bushing from the factory. I call the dealer, they say "bring it in". I explained to them that it's a long trip and I would prefer them to just get me a clutch. They hesitantly agree, ask for a bunch of pictures and they submit a warranty claim. I also asked for another new belt (they warrantied the first one that blew) as it has been very hot. The dealer tried to fight me because they had already warrantied one. I explained to them this one had been very hot and I would gladly bring it in sometime to swap "we'll see what we can do". By this time it is early March. 25 miles on the sled. I wait. They finally get back to me in April. The claim on the clutch and belt were approved and I can bring the sled in to have the new clutch put on whenever. I was hoping they could just ship me the clutch, but they wouldn't- which is ok, but I am a little frustrated beings it wasn't fixed the first time I brought it in. I push them off on fixing it as my season is over anyway.


Fast forward. I had an appointment this Tuesday to have the clutch put on. I go to load the sled up and its running on one cylinder. I think... ok most likely a plug, I am not gonna mess with it, I will let dealer take care of it. They can look it over incase it happens to be something else.

I walk into the service department, tell the kid the sled is running on one cylinder, likely need a plug. He goes "you want us to do a preseason check then?" I said- "is it free?" him-"$150" I said "no... it's got warranty still, doesn't it??" him-"yeah, but a plug is considered a wear item."

I go unload the sled and think about what he said. I come back and say "hey, I get it... I don't know for sure that it's a plug, can you guys just get it running properly?" .... he says "yeah" and writes some things down. At some point there he again explained to me that a plug is a wear item like a ski or a track and cannot be warrantied.

Wednesday morning I get a call "Hey we got that clutch replaced for you and looked into your runability issue. It was a fouled plug, its running good now. Going to be $105.XX"

I was mad like I have never been mad before. I explain to him that I paid $22,XXX for that sled in January. Wasted a 4 days riding trip to Colorado. Have now hauled it to the dealer multiple times. All I WANT IS THE BRAND NEW SLED THAT I BOUGHT TO RUN LIKE A BRAND NEW SLED AND IT NOT COST ME ANOTHER DOLLAR. I don't care that a plug is a wear item, I GET IT. It could have been some other issue. Put a $3 plug in it and be done. At some point in there I said "we should not even be having this conversation, it's unbelievable. $100 for a spark plug!?" .... the kid says quietly "two spark plugs....". The conversation ended by him saying he would talk to the service manager about it. I told him I would pay if I have to... but it's not right.

I would never take a sled to a dealer for a spark plug and expect them to warranty it. But I guess I thought beings it was going there anyway they would just take care of it no questions asked. Wrong.




Am I crazy? Should I pay for the $100 set of plugs and move on?
sounds like a lemon law waiting to happen! you should talk to an attorney, you might have a good case.
 
I just sold the sled a couple weeks ago. I never got an attorney involved, nor did I ever consider. I just take my business elsewhere now.

Update on the sled… I had more issues in 350 miles with this sled than combined with the 6 other Poos I’ve owned since 2012. All the other sleds had been pretty much flawless though, other than some TSS and TPS issues. Cost per mile on this sled was horrendous… over 5x my previous 3 sleds (which weren’t great to begin with).

Shortly after I got my clutch issue resolved I had injector harness issues, which I fixed myself. Had the turbo oil pump replaced by the dealer as it was leaking. Broken primary spring at 350 miles which is no big deal. Occasional fouled plugs in the morning. All that said my last 5 rides on the sled were phenomenal. Wicked fun sled.
 
I think that explains why he who shall not be named loves these sleds AND bright yellow Ferraris. For some people, the agony of break-downs and stupid gremlins actually enhances the ecstasy of that perfect day where everything works right. But that's a poor excuse when paying a little more on the front end for better components, smarter people putting the sleds together, and a real look-over and test run before it leaves the factory would eliminate most of these issues. Some might say the plug fowling is minor, but it's still nuts: I've run a ton of oil through my old Pro (top end break-in, and I still pre-mix some and have the oiler turned up), and I mix in some avgas. I've never fowled a plug. I know a lot of new Poos don't have that problem, but you'd think it would be eliminated with the electronic oil injection and more sophisticated engine management they've got.
