Charging probmlems

Ok... seem to have found the problem...but why and where is the fault?

When messured the volt at the battery it is 12.5 and goes down to 12.4 when I start the bike, the book says it shoud be about 13.7 when at 3000 rpm

I also felt the regulator gettin hot so i guess the alternator is working(dont know how to messure this)
I know I forgot to ground the regulator when i rebuilt my subframe, and ran it a bit coud this have fokked it?
Anny ideas what my problem is and what I can do?
Is a regulator xpensive?

Might want to check the for sale section here or ebay for one from an R6/R1/YZF600r Thundercat/Euro FZR600R and then do this.
