I just changed the air filter on my 2012.
First step was to remove the tank. It's much easier on the 2012 than the earlier versions. I disconnected one set of electrical wires and the fuel line but couldn't figure out how to disconnect the wires to the fuel pump
So I just rotated the tank and left them connected.
Then I removed the top of the Air box which was a real PITA. After doing that I discovered that it was all a wast of time. The air filter slides out of the box and only required removing one screw.
So I put the box back together.
The filter wasn't that dirty but I'm going on a trip and wanted to check it.
That cheap little filter costs $40 from Kawasaki so I used this $10 aftermarket filter
I put everything back together with no left over parts and took it for a short ride.
The bike is now ready to head out west.
Now that I have done this once, it will probably only take an hour next time.
