Locate your VOES and take it off-you've gotta do this operation on the bench or sitting at the dining room table or somewhere besides squatted by the bike fumbling under the tank. Usually, the VOES is on a bracket between the cylinders somewhere behind the horn or coil.ince a VOES is an electromechanical device it can fail (hell, anything more complex than a cannonball can fail-and eventually will). If it does fail it reverts to the retard mode full-time so there's no danger to your engine, but you lose the benefits of an advanced curve.
