you need to put the bike in neutral,and pull the clutch in and put a tie strap around the clutch so it holds the clutch in. make the tie strap to where you can take it off with little effort. then hold all 3 buttons down on the pc and dont let them go,turn the bike on and let the instruments do their thing, then start the bike,after the bike starts, then let off the buttons. go to the high side button and tap it until the bars go all the way to the top.let the bike run and watch the pc until the bar goes from the top to the bottom,that means your pc is set!! turn the bike off!!! to be safe it's always smart to run the pc all the way up on the high side when spraying. i would drether have too much fuel than not enough!!!
