Tim, what does your air filter look like?

This I know, that post was in response to ninjabob implying you can't use a yosh box and a dyno toward the same goal.

I checked that about a month ago and it looked fine to me. Not obviously blocked or dirty from that I could see.

Well it doesn't have a lambda sensor AFAIK which rules that out. Does it feel fluffy/rich at all?

Yup, it definitely "feels" rich to me. The pick-up isn't very "clean" at small throttle openings and it has tendency to "hunt" when on a constant throttle at about 4-5K which gives me the impression that it's running rich -- and the pathetic MPG would tend to bear that out, too -- but the front plug looked absolutely fine today.
