Lisa, start the bike up, and verify both the 1-4 and 2-3 F marks are aligned at idle with the strobe. Next, gradually increase the RPM until the advance stops moving. Ideally, the pointer will be lined up between the advance marks, equal between 1-4/2-3, and occur around 2500 RPM. If full advance occurs lower than that, the advance springs may be stretched. This would also apply if there is a significant change noted between static, and dynamic testing at idle.
