I have a question just for my knowledge and maybe some others. I've noticed on my '08 SG with 90,000+ miles now that the voltage meter at start up is around 14.5-14.7 volts. After riding some time on the freeway, it goes down to around 13 volts and then when I get off doing streets, it goes back up to 14.5-14.7 volts. I have a new battery using a battery tender, a new voltage regulator and pretty new stator. It's pretty much done this since day one with the OEM manual stating the gauge will read 13v-14.5v when running. Question: is the fluctuation to 13v at freeway speeds the regulator cutting back the voltage with the battery now fully charged at freeway speed/rpm and recharging at the 14.5-14.7 when on streets or.....? Thanks again for such a great site!
