Re: airbox flapper

Is the airbox flapper is all the way open up to 7000 (8000, or whatever) rpm and all the way closed above 7000 (8000, or whatever).

When putting in a new air filter and plugs this weekend I noticed that my flapper is about half way between UP and DOWN at idle. As the revs come up it moves toward the UP position doesn't get there until just before it slams DOWN at around 8000 rpm.

I guess at 20,000 miles it's about time to do the checks in the manual for the HTEV and the HVIX systems.

Any words of wisdom/confirmation/correction/whatever regarding this?

as always...TIA.


<<never mind....I found it in chapter 21 of the service manual. duhh>>
