Is it normal for the alternator to charge at 12.5 at idle. It jumps up to 14.0 volts at 1200 rpm. Not having any issues with the bike

For a stock alternator, that is what I would expect.
You usually don't start getting real output till at least 1200 RPM's.

For a stock alternator, yes.

For a higher output aftermarket alternator, no. My Compufire charges at 13.8 at idle.
