Re: Bike charging (not the 1200) Stupid question?
I carry jumper cables, but only to charge, not to start. I don't think you'd have any problems at all if you just let the bikes sit for a while and let the other battery charge off yours. Disconnect, then start.
Even with my battery tender, it only takes a couple of minutes to put enough charge into a dead battery to get it started.
When I built my jumper cables, my first thought was to use the SAE connections, but then changed to smaller clips because not everyone I ride with has the SAE's.
