Alright, update:
I started testing the charging system myself even though that one shop in the OP said it was fine. I had no accessories hooked up to the battery except the Power Commander, which is obviously necessary unless I unhook it from the fuel injectors.
So, the battery only dips down to around 10.5v when started. That's good. It sat at about 14.4 to 14.5v at idle though, which I thought it was supposed to sit at mid-13's when idling. It stayed at mid 14's even when revved to 5k RPM. But low and behold a minute or two later, it's like the charging system just quits. It drops back to normal battery voltage, about 12.7, then slowly falls, falls, falls. I'm obviously just running off of battery. This would explain why the shop said the charging system tested fine the couple minutes he had it running, but then it happened again once I got back on the road.
Right as I was about to cut it off, I saw a little steam and a little coolant started to drip from the bottom of the bike and the temp went red. I thought a fitting may have backed off or something. I took the fairings off today, and I didn't notice coolant anywhere except for on the oil cooler under the reservoir overfill tube. So I'm assuming the bike just overheated from being revved up to 5k RPM in this over 100 degree heat, and what was in the reservoir boiled out? I just want to verify this with you guys that nothings wrong before cleaning it off and getting the fairings back on.
So anyway, I topped off the coolant, and wanted to verify the voltage thing I found out yesterday. It did the same thing. Charges fine for the first few minutes, then it slowly drops off as if it's just running on battery.
Does this sound like the R/R is failing once hot?
Thanks.
