Bert has gone through the motor carefully, thinking through every aspect of its running. Any anomalies uncovered would have necessitated it being stripped down for inspection and attention to the affected area. Oil is flowing through the crank, as it should and the motor turns smoothly with no untoward play or issues. The bore has been inspected and passed.
Reuniting this rare magneto with the bike it would have been originally fitted to is a truly satisfying moment, ahhh…!
