the two button head screws that fasten the adjuster plate to the sprocket (Figure 1). Use the HEX-AJUST® Tool provided to set both the sprockets at the “0” position or any increment of advanced/retarded timing desired of up +/-5 degrees (Figure 2). Retarding the cam timing will increase high RPM horsepower, and advancing the cam timing will increase low-end torque. The “0” adjustment will be an Original Equipment timing setting. Make the same adjustment to both the LH and RH sprockets.
