Ran open airbox today

[CIP57_imp]

Wow, that's quite a finding! To go from an OEM filter and airbox to nothing with no detectable difference has remarkable implications regarding mods we're doing.

You really couldn't detect ANY difference at all? Did you get thru the entire revs range?

If only we all had home dynomometers...

Spaceman,
I was amazed, i red-lined 1st and 2nd and could not feel any difference. I was expecting the bike to run like crap. I plan on installing a cat free exhaust and air-box mod before dyno work so figured i would try this out. I remember putting K/N filters on carbs and eliminated the air box back in the day and fuel ( Jetting )was required.
