Hi Neill.
I took a jiffy marker cap with me when I went to pick up my new bike from the dealer last year. I shoved it into the large hose from the air box side before I drove the bike home (220k). Make sure you put the line back into the air box.
I had that in there for quite a while before I finally had time to take the AI stuff off. I don't see any reason why you couldn't leave that line plugged up all the time.
