2011 Kawasaki Ultra-LX
My riding friend here has a 2011 Kawasaki (Normally Aspirated) Ultra-LX and I went to help him fire-up his ski earlier today - after its winter nap and it started fine - yet ran "rough".
I pulled the plugs and #1 had some "schmegma" and corrosion caked onto the electrode area of the plug. The rest look fine. I am assuming corrosion from possible H2O being ingested into that cylinder - and I could just imagine what the combustion chamber and those valves look like - probably also caked with the same.
Anyways - ski has 70 something hours on it - and carries the Kawasaki GTPP Extended Warranty.
Last year - he did mention that it would run rough when he first accelerated - then everything would smooth-out, and only noticed some "stumbling" upon 1st accelerating.
Curious if this year possibly had casting flaws in the cylinder head castings?
As always - Many Thanks !!!

Thanks Guys - and yes, when I started it - I could not believe water was being pushed out of the water box when I was running his ski for the 1st time this year.
I changed the plugs and same deal - missing - probably due to issues with that cylinder.
You guys should be out "hitting the waves" - Reference:

Well my buddy got his shit back from the Kawasaki Dealership - it seems the "collector" had some salt H2O corrosion causing water to enter one of the cylinders - and I can only assume that would be cylinder # 1 - which had all of the "schmegma" built up on the spark plug.
Dealer allowed him to take his ski N/C pending approval from Kawasaki - as he has the GTTP Extended Warranty.
Dealership stated that they were not certain if Kawasaki will cover "corrosion".
I looked at the exhaust manifold in the "collector" region - and if that was my ski - I would have cleaned everything up, bought a fresh tube of "Right Stuff" - added some new gaskets - and put it all back together.
For you Aussies - Right Stuff = Silicone
Now Corey - I know what you were thinking when I mentioned Silicone :yay2:

i now use composite gaskets as suggested from a shop over here. the tin oem gaskets just dont have enough crush, i would think any gasket maker is only going to work for a limited time. the salt seems to find its way through. as you know i was chasing this issue for around 50hrs but all sorted now. silicon love my big silicon (.)(.) and so does she dont know what makes me happier those or my ski. wtf its not my ski
