Motion Pro Degree Wheel
Manufactured from .052" thick with a 6¾” outside diameter and a 6mm center hole. The black anodized finish allows for easy to read increments. This degree wheel can be used on all 2 cycle engines to check or setup the port timing or ignition timing. May be used on 4 cycle engines to check or adjust cam timing or ignition timing.
For our single fire H-D ignition this is useful to find 35 degrees before top dead center (BTDC) on the rear cylinder.
