its a small black hose, about 3"long, in the middle between the air box and engine.
remove right side cover and you can see it.
I used a long fat flat blade screw driver and pryed the hose up and off the nipple on the motor.
didn't loosen the air box.
I'm sure I can find it now.(thanks for the offer though) I was looking at the manual and it doesn't really show where it hooks to the engine. I'll pull the side cover this weekend and have a look. I'm also going to move my air temp sensor into the first K&N. I know there are those who don't think that helps anything, but I feel it was designed to be in the intake air stream so that's where I'm going to put it. I godda believe it will get a more accurate reading there.
Make sure you pull the black plastic cover, screwed on to the frame stay in front of the painted side cover. The breather hose is best accessible by removing that one.
