Welcome to the forum. Where are you located? It sounds like you may have gotten the California emissions model. I haven't heard anything about Kawasaki changing the roll over valve.

 

[BobX2]

Yep. This is what I did to my 2021.

A few things.....

• All 2021's are 50 state models from what I can find. The 49 state model was made for the 2020 model year only.
• The 2021 models also have the fuel tank vent issue, mine did anyway. Ajb9 nailed it with the Tanks Inc solution. Works for 2020 and 2021 models.
• Installing the Tanks Inc. solution for the fuel venting problem does not fix the fuel gauge inaccuracy issue on this machine....at least it didn't fix it for me.
• This is an amazing machine! So glad I traded my Teryx4!

I chuckle when I see folks saying that changing the valve fixed their fuel gauge inaccuracy issue. Like you, I can say for a fact that it does nothing for it, and how could it.

Yep, mine functions the same after the valve fix. Crappy!

LOL. I've never had a machine where the fuel gauge was very accurate, (none have ever been quite this bad) so I just go by miles ridden. I also top off before every ride so that makes it easy to keep track of. I can easily go 100 miles in the KRX with nothing to worry about, and it's rare for me to get to 100 miles in a day with the trails I ride.

Got mine in too, just have to install it. Does it matter which way the valve is installed?

Yes it does. There should be instructions with the valve. It must be mounted vertically. I think the big end goes down, if I recall correctly. If there are no instructions, you can figure it out by blowing through it. Hold it vertical and blow through the top. If no air goes through, that is the bottom. That would simulate a roll over situation, and not allow gas to escape.

So that's what the blue pigtail is for under there. Damn Cali and all their emissions standards. That's a bunch of crap you have under your console. That's all just empty space under mine, with the blue plug just hanging out all alone and nothing to plug into.

 

[BobX2]

I don't know how it would react to you doing that. You could probably just unplug it and see what happens. If it doesn't like it you would probably know pretty quick. Tough call. I heard that VF John has a different flash for Cali models, so I would guess you kind of need all that plugged in for the ECU to be happy.
