It was at 30 degrees. But the more i read about dual plugs the more i think it can be retarded more. So down to 28 from 36 (stock) is 8 degrees total, still within the 10 (or more!) that many suggest works well. An old lengthy article about BMW airheads shows even bigger reductions into the low 20s, but that is too big a step for me. One small change at a time. If this works maybe i will nudge it down more.
