Update: After the bike sat overnight, It started flawlessly this morning. Makes me believe the recurring problem is either completely random, or perhaps more likely heat-related.

Second, I don't think the HES signals control the injectors. They control spark. Actually they probably have some input to injector signal, but I'd be a little surprised if the HES would cause the injectors to fire randomly, or at all.
Jim, I appreciate your opinions and wisdom, and certainly express your skepticism as to the diagnosis, but please follow up with a firm belief in an alternative diagnosis. What else could cause my injectors to fire randomly and rapidly with ignition and kill switch "on", without the motor running?

(My bike is a 2000 R1150GS with about 103k on it, BTW)
Kbroderick, let me know if the new part solves the problem.

Thanks for all replies!
