Procedure
- Rotate the flywheel to position the magnet away from the ignition module bosses.
- Install each module to the crankcase bosses; slide modules up away from the flywheel and snug the screws.
- Rotate the flywheel to position the magnet directly under one module.
- Insert a 0.30 mm (0.012 in.) flat feeler gauge between the magnet and the module.
- Loosen the screws enough to allow the magnet to pull the module against the feeler gauge.
- Torque the module screws to 4.0 N·m (35 in. lb.).
- Repeat for the other ignition module.
- Rotate the flywheel back and forth and check the gap with a feeler gauge; final air gap 0.280/0.330 mm (0.011/0.013 in.).
