I have never checked the charging system on my Vulcan, but on most 12V systems, the voltage at the battery should be around 14-14.5 volts at the battery at any speed above idle. I have voltmeters on both my car and truck, and they both show around 14 volts. I would say you still have a problem.
I would have replaced the R/R with a new Kawasaki oem part, installed a quality AGM battery, and if the voltage above idle is still not over 12.XX volts, I would suspect the stator.
From a thread on another forum, I found that the Vulcan can be ridden several hundred miles with an inoperative stator, as long as all the lights are turned off, you have a fully charged battery, and all it is doing is powering the ignition system. If you had a battery charger and a jump starter, you could still use it for long distance commuting in the daytime. My race car has a total loss ignition system, but I also have a 20 amp charger to keep the battery charged up between runs, and to start it off of. Jerry.
