My 2008 20,000 XT started posting intermittent cel warnings. The idiot light would turn on and off when riding, never solid. I connected the laptop and the bike was posting low voltage CEL errors. The stator tested ok with a volt meter. With a volt meter connected to the battery I saw a low voltage of 11.3ish volts idling, then it jumped back up to 14 volts. On spec I changed the voltage regulator. Over 200miles and no cel light. Just putting it out there.

Is it possible to rebuild the voltage regulator? New power transistors/diodes?
