Today, I had some time to tinker. Took off the side panels and traced the electrical wires... until they ran under the tank or I couldn't see them anymore. The battery terminals looked kind of funny, like they were connected in a hurry. The red terminal wire connector wasn't seated flat down on the battery terminal. The screw threads looked like they cross-threaded the flat wire connector so were angled off the battery terminal with only one side in contact. I hadn't noticed that before... I guess I didn't pull back the red plastic hood off the terminal completely until today.
While at it, I checked every wire connector I could find and made sure positive contact was made. The. I checked the air filter and box... Which seemed to have a very small amount of oil in the bottom.
Don't know if that will solve my electric gremlins, but I did enjoy getting to know my bike a bit better.
