After reading several threads of air box mods, I decided this morning I would add holes to my inner air box. I added (10) 3/4" holes in random locations. Afterwards, I went to start the bike and it had to turn over several times before starting...that never happened before. Once it did start, it barely idled @ 500 rpm. I got out the service manual and it said it should idle at 1050 +/- 50 rpm so I adjusted the idle screw to get it back up to 1000 rpm. Is this something anyone else experienced? Its on a XB9R with a XB12R air box if that matters.

You've got to ride it a bit to let the bike "learn" it's getting more air.
3500rpm or better for a minute or two.

^~~what he said. Go get on the freeway and cruise at like 65mph for a little while. You'll likely have to readjust your idle again when you get back. Ride long enough that everything's nice and warm.

Thanks!! Now that ya'll mentioned that, I remember reading that somewhere. I shouldn't be so paranoid and let the bike do it's thing, uh? Apparently, the bike is smarter than me.Only had the bike for 3 weeks and trying to learn a lot in this period of time. Thanks again!!

Did you unplug the Intake Air Temp sensor? and maybe forgot to plug it back in?

Punkid8888, No, I didnt unplug anything. After riding it for awhile Saturday, it corrected itself. Back up and running fine. Thanks for the suggestions guys.

Did you notice any performance difference in the bike when you added the holes in the inner air box???

To be honest, I didnt have much riding time on it before the mod to compare it to. My opinion though, it definitely has more throttle response. I am please with the outcome.
