A little more detail would help, so you've got the Pamco installed yourself? If yes, the way to set timing is to start the bike with only the Pamco wired to a battery. Once you do that, grab a timing light and hook it up. Once you do that start the bike, the way to set timing is to turn the sensor plate clockwise or counterclockwise to advance or retard. If that's confusing, I'll go further. What I mean is with the cam cover off on the left side of the engine you see the sensor plate with two screws securing. Loosen those screws and turn the plate until timing is correct, then lock it back down.
