Here are my measurements (made 10-25-11) on a 2008 carbed America with no mods, original battery. I used a Fluke and a Greentree VOM. They both agreed.
Before start, Bat 12.4
After start I got 13.1 at idle (1100 rpm) which rose to 14.8 slowly.
The voltage held at 14.8 until revs went to 2500 rpm then the volts dropped and held at 13.7 until 6000 rpms. After the bike was warmed up (short ride) all the measurements were about 2/10ths higher.
I am about to replace my original batt due to age before my upcoming trip to Strawn, Texas. Yabba-dabba-do. I just had to throw that in there.
I will look at the 30 amp fuse though, I think I heard of this once before.
