I did it on my bike when i first got it, only because it seemed like a good thing (translate

couldn't hurt anything) to do and it was cheap enough. After 40K miles I don't think it makes any difference. When we where at the RLAP in Houston on April 2 I had to turn it off because
without it the bike is easier to control at slow speed. There was a reason Honda made it stop after the engine warms up. I also found that my bike runs not as lean when it's turned on at 50 mph. Every bike seems to run slightly different and you may have better results.
My conclusion and personal opinion: I shouldn't have done it. Valkyrie that have a lean spot at rpm below 3000 may seem to benefit from it, but why not fix the lean spot and get better response, hp torque etc and mpg if you can keep from twisting that throttle.
