Low voltage while running.
I am new so please dont yell to much because i am sure this is somewhere in here just didnt see it, yet. Any how i have been having a problem with my bike shutting off while idling when i hit the breaks. Looked around heard that its prone to weak electrical and to replace lights with leds. So i replaced my break lights with led replacements and replaced head light with HID both because they draw less power. once i have done this it runs fine now no problem. I have however noticed that the battery seems week, it had a warranty so i swapped it out. better but still seems to not crank over as fast as it should unless i keep it on a battery tender. So i finally checked the voltage at the pig tails for the battery tender while running. about 12.6v before start, 11.95v after start, reved to 3000 rpms got 12.11v, took it for a hour and a half ride came back. as i was letting it run and getting my multi meter again the cooling fan came on a killed the engine. started it back up with a little problem but not too bad. Checked it while running this time it was at 11.4 v reved again to get 11.5v. now my multi meter may not be the most accurate thing in the world but i know its close enough. So WTF is going on? is it a voltage regulator or the (and i sure hope its not) stator? or something else?
