Topic: Runing too rich with high humidity/heat - is there an easy adjustment for this?

[RFogelsong]

I've got my 550 jetted to run great from 30 F all the way to 90 F with regular (up to ~60%) humidity levels.  However, recently we've had 95% humidity with 85 degree weather and my bike acts almost as if I have the choke partially on (rich).

Is there an easy adjustment to make for a few days so it's running good in these conditions?  (plugs or air screws maybe?)

If you are in the PI where it is always warm and humid you can jet for that.  For us of that live where the temps and humidity changes we just shoot for the middle. The adjustment screws don;t effect the above  1/4 throttle.

Yeah, I was wondering if maybe switching from a standard to a k&n or foam filter in the airbox might give the bump needed?

I was hoping someone had a trick that I could do in the daytime and then easily be put back if I wanted to go for a ride in the evening when it chills back down.
