Actually, with the key on and the bike off, the bar will disappear. you have to start it on a busa to get it to show back up. OK, to set the throttle position, connect your PC3 on the bike to your computer. start the PC application. on the right side of the application it should tell you your throttle % and rpms. go to the top of the screen and click "power commander tools". from that menu select "set throttle position". Now you sould have a screen with some numbers on it. hit reset at the bottom. Go out and twist your throttle all the way open then let off. your throttle should be set now. if you get an error message when you try to reset it, go out and start your bike (i cant remeber if it has to be running) and do it again. When you twist the throttle when it is running, do it really fast. By doing it fast, you should be able to open it all the way up and back before the bike can respond. Dont worry the computer will pick it up just fine.
