After reading a thread on here I decided to remove the secondary flies on my Gen II. The removal goes as follows: Take off seat... Take out the tank hold down bolts and prop up tank ( I use a stick to make it higher ). Then take the airbox lid off and set it aside ( phillips screws ). Now you can get to the flies from here. What I did was to close the flies with my finger and work on the other side away from where I was holding. Two phillips screws on each plate is all you remove to get the plate out, I highly suggest a magnetic screwdriver. If you happen to drop a screw the other throttle body plates will keep it from going into the motor as long as you don't twist the throttle. Now after the four plates are out just put it back together.
My review of the performace is.... it does feel like the throttle is more crisp. I only rode about 25 miles so far so I will update this. I have tried a TRE and this mod feels about the same as that. I don't have a TRE anymore so not sure if this adds anything on top of one. I have no idea if the A/F is still ok but the bike does run fine with no flat spots or issues. I did have the bike running to watch the flies and they were closed even when I thottled it up some ( not sure what RPM they open ). When you get to them they are open but if you start the bike they close... not sure if it was due to the bike being on cold start? Anyways if anyone else wants to add to this ... please do.
