Installation Tips

• Disconnect the spark plug boot and kill switch wire from the old coil.
• Clean the coil and flywheel mounting surfaces before installation.
• Install the new coil, leaving the mounting bolts slightly loose.
• Set the air gap between the coil and flywheel magnets. A standard business card (approx. 0.010 in / 0.25 mm) can be used as a feeler gauge.
• Rotate the flywheel until the magnets attract the coil against the gauge.
• Tighten the mounting bolts to secure the coil in place, then remove the gauge.
