Anyone else have an issue of fouling of the spark plugs? Krx would not start. It would crank over and everything. Take into consideration this thing is brand new only 85 miles on it.

Are you starting the machine and stopping it frequently before it is up to operating temp?

Only a few times to move around in garage or to load up. But I also recently installed the trinity stage 5 slip on exhaust right before this all happened.

I’d say the exhaust is making it run rich. I’d break in the engine before adding mods.

Yup. I’d wait to add any modifications to that motor until you have it broken in. Frequent start/stop of the engine can foul plugs quickly.

I am having the same issue. Mine is completely stock. Went to move it when it was really cold out (needed to get tractor out) and it ran rough an died. It will crank but not run. What size socket does it take? I bought extra thin 5/8,13/16,16mm,18mm and can’t get them out. Does it take a special tool from Kawasaki? What am I doing wrong??? Lol. Very frustrated and about to load on trailer and take it to a dealer.... I never would of thought it would be this aggravating to change two spark plugs.

If it has factory warranty why even touch it? Take it back.

The plugs are a 14mm, I didn’t actually have a spark plug socket that size at the time. So I used a magnet to get them the rest of the way out. Cleaned off the carbon and they worked fine. The plugs are not covered under warranty, but my dealer had some and gave them to me. So I swapped them out and found them on partszilla as well for only like $15 a plug instead of Kawasaki $37. My dealer was telling me he’s been having the same issue. It’s from being so cold, and short starts to move the machine and not letting it actually get up to temp. So far with new plugs I’ve been letting it warm up everytime I start it. Very irritating that any Polaris, or any other brand can start and stop engine whenever they want and it doesn’t affect them.

Thank you! I just got off the phone with the dealer and he said 14mm also. He gave me two spark plug numbers, one was Kawasaki and the other NGK. He acted like he hadn’t hear of it doing that but did mention another customer just bought some plugs a couple days ago.

Justin, I also have a Trinity stage 5 slip on exhaust on mine. I have over 600 mile on my KRX before I installed it. Do you have many miles on the new exhaust? I was told it will take about 20 miles running your buggy at different throttle positions for the mapping system to relearn the exhaust. Some people don't believe that but I can testify that about half way through the ride this weekend my buggy was running great. I am sending out my ECU today to VFJohn for a stage 2 reflash.
