Spark plugs?


had to get the sled out of my wagon... got a new one.... anyway the mf wouldn't start , lots of battery, i ALLWAYS let it warm up to where the rear cooler is very warm b4 shutting off.. anyway gonna put a set of plugs in , from what iv bin reading on here would everybody agree the stock plug with .20 gap is the ticket? max17 tune... or the double elecrode mr knapp tried? just lookin for the recommended best replacement.. thanks

NGK CR8E(k) @ stock gap (.025)
I had this in my notes. I'm hopeful Knapp will reply and verify.
Yes, others suggest .020 gap.

I typically go one step colder with a CR9EK. I believe stock heat range is a 8. And I don’t tighten the stock gap on the EK dual electrode grounds either. Just run the gap as it is out of the box .024 as I recall. Even .025 is fine on the dual electrode. I’ve not seen any misfires with these at that gap on any of the big trail tunes.

interesting.... go 1 colder just bc its duel electode? if was a single electrode stay with the 8? just curious... im gonna go with the cr9ek regardless
 
Agree. Pretty much no matter if it's a sxs, utv, motorcycle, atv, sled; run coldest plug ignition will fire without fouling.
I've been running CR9EK at .024" gap (what I've measured out of box). (Stage 4). Never had one foul. Even stock, I ran CR9EIX NGK (1 step colder than stock (which is CR8EV) and iridium tip). Never had one foul.
That said, I never let my sled sit and idle for 20-30 minutes and always let it get to pretty much operating coolant temp before shutting it off. I never fire it up, drive out if trailer, and shut it off cold.

I want to know what kind of magic you guys are using to get the clutch side plug without at least sliding the gas tank back/over! No way for me. That tank has to get moved just a bit for my meat hooks to fit.
I'm wondering if removing the front console would make it easier to access plugs.
 
About an 8" pry bar on the coil as is comes off plug boot at top. But not a lot of force. You'll see....pop, pop, pop & done
Hood off, pry comes in from the front

Read above. Yes, take the hood off.
 
You can get them out by just taking off the right side panel only. You need some extensions and universal joint I use a magnetic plug socket also which I highly recommend. Not that big a deal to take the hood off either though
 
The console that covers front o
I haven't, just the hood. But if you find things are too tight for your liking, you can remove the console and pull the fuel tank back. Not that big of a deal
 
My hands are too big to reach in there.ive removed the hood but I'm wondering about removing the front console ,the one that covers gas tank will give better access?
