VALVE TIMING ADJUSTING GUIDE
■ PONCAM Camshafts will not require any Valve Timing to be set as the Valve Timing is preset from factory
on the Poncams.By using the pulley you then re-adjust the intake timing to suit your needs starting from
the center position (0 ° position) and then adjust ± 3 scale (3 °) range.
Adjustments of ± 3 on the scale = ± 6 ° (crank angle) of timing change.
(The products range of ± 10 on the Pulleys scale is ± 20 ° of timing that is changed)
※ The PONCAM has already got the valve timing adjustment preset from factory but there are times when
the valve timing is not suitable for the matching with the cylinder head, head gasket and the
cylinder block at is being used.

WARNING
■ Keep the pulleys at the standard 0°DEGREE position until the engine build is completed. If the camshafts
valve timing is not setup properly then the engine amy not be able to turn.
■ Great care and attention to detail must be followed when making adjustments to the valve timing so not to
cause any contact with the valves and the pistons or terminal engine failure can result from the contact made.
