I did try it, but it seemed to be even further back than the k5 boot. I'll give it another try just to make sure.

I may have figured out your problem umberto. There were a few changes to the intake tract between the 03 and 04 KX250s. The airbox, airbox boot and intake manifold are different between the 2 years. The 03 airbox to airboot mounting flange is flat(airbox side) and on the 04 the airbox to airboot flange is recessed about a 1/2" or so. This is probably why the airboot is squashed using the 03 airbox. I think if you go with a 04 KX250 airbox and the 500 boot with a adapter plate you should be good to go.

I will try to get a pic tonight of the 2 airboxes. I have both.
umberto:
I'm glad you thought of that, I was about to do major surgery. :-D
