Engine Timing

      Several runs were done with the engine timed at various full advance settings (full advance on this engine appears to occur at 6k RPM. The advance is controlled electronically by the ignition computer, but may be modified via techniques described in K bike FAQs on timing). In the case of the runs, we also took a new 'control' run - which is Run016. This was felt necessary since conditions (temperature of the shop, temperature and diameter of the tire) may have changed by this time (we had done a significant number of runs and these runs were actually taken after the runs for mixture that follow.)
