12.8v standing voltage is a good number and = a full battery.
12.08 with the ignition on is also a very good number so I would say your battery is fine. (testing this over a 2 minute period would be better)
14v also tells me your charging system if working well.
If those numbers are correct and they persist your bike is fine.

Live life on the edge you will see more that way.
Ridding a motorcycle keeps things in balance.
At the end of each trail and at the end of each day history is made.
