Russ, I have been thinking about a 6 and a12V in series for 18 V. We don't run
a generator and ignition systems are designed for generator voltage around
14.5V. I read somewhere that MSD systems are very happy at 18V. Not sure where
you find a 6V battery these days... I didn't see any at Walmart.

obviously most of the bike's circuitry wouldn't like 24v; probably fry the
ECU, for one thing. What Sparky and I were discussing was the starter on an
isolated circuit, with the remainder of the bike still running 12v.
Running 2 batts in parallel (or one BIGGER batt)-- as you suggest-- would
give more amp-hours, and the ability to sustain cranking. The way it would
help an over-worked starter is that the starter tends to stall, and draw the
voltage (in the small battery) down below 12v (actually, 12.6); with a lot
more amp-hour capacity it can't draw-down the voltage, and there is more
likelihood that the engine will crank.
24v would make it almost certain that the engine will crank.
