So I have a 2010 Iguana, bought new in 11. Always idled up to 115F before touching the throttle.
This season I lost spark???? On the right side. Changed plugs, caps, and wires and I'm done.....

Took the sled to a reputable dealership and got a couple of phone calls today and long story short...
I was told that fuel delivery and injectors are good, reeds are good, spark is good, 118psi X2
Spark is good when testing on the outside, but once put in the hole, works for about 5 seconds and then drops to one cylinder
Skirts are scuffed a little, (for me this is just a sled eating a little snow)

So..... I am told that I have the 3 basics to make a naturally aspirated engine run, but my issue in a crank seal. And because it is a crank seal, the bottom end isn't making enough vacuum to bring up the over abundant fuel from the crankcase, to make the engine run.... which absolutely makes no sense to me and Trevor what so ever
I told the dealership to stop diagnosing my sled and I'll pick it up on Wednesday.
Do any of you (with the exception of Rhodesie "Trevor" who helped me out today) have any idea what's going on?
Thanks in advance :beer:

Any chance you got antifreeze fouling the plug on that side? That would do it as well.

If there is good compression on both holes and spark on both plugs maybe the spark is intermittant on the bad hole? Compression won't be intermittant.

would it not be firing because your air fuel is way off due to leaking crank seal?

I agree, I was thinking laser thermometer check for temperature differential. switch plug wires re check

Your dealers diagnoses is flawed or you miss understood as there is no base vacuum to bring the fuel up. The base is pressurized, basically when your piston is on the down ward stroke the volume pushes the mixture into the ports to the chamber. On the upward stroke the reeds open because of vacuum to allow the mixture to enter the base..ONLY.

Your title is kinda miss leading because at first i thought you had no spark till i read your post, you have a cylinder going dead or is dead.
I suspect from reading this that there is spark, but is the plug going wet (fouling)when it goes on one cylinder?

The way you explain it, is like watching the video and it does make sense

My title is not misleading as I am only getting fire in 1 hole. How can I have a dead cylinder at 118psi X2 ???

I am going to start it soon, and see if it fires on both. If not, going to pour some chainsaw mix in the hole and see if it fires like that?
Might prove the video right...…. or wrong???

Trashy... does it fire up on 1 cyl at least. if it does run on 1 cyl then start spraying WD40 around the crank seals on dead side. If it sucks in the WD she may fire up. Just like in the video.

Who likes apples??????? lol
So long story short...... An extremely smart man, with a ton of common sense and the ability to think out of the box. Narrowed my sled to wrong spark plugs!!!
Even though I was told that the other ones that I bought were correct, they weren't.

So mucho grassyass to Trevor and no thanks to Cycle Works, who can give me back my 300, plus 1200kms on my truck, burning premuim fuel only, pay for Trevor's time and his inconvience.

Going back to Medicine Hat after work tomorrow, to pick up my Iguana :)

Watch me NOT endorse Cycle Works :(

So who sold you the wrong spark plugs and what kind were they? All specs I can find call for Champion RN57YCC.
