If you have a drain it will be in amps not voltage. The battery fully charged, but not while being charged should be close to a static 13.7 volts.
Connect a multi-meter in the amp function between the battery and the bike, (start on a high amp setting). all power to the bike must run through the meter. Do not try to start while using a amp-meter. this should tell you if there is a constant drain.
Clocks and such may pull a few milliamps, but if your batter is dead in an hour or so, you may have a bad battery or a short.
Charge battery while disconnected from bike, disconnect from charger, wait at least 48 hours, hook up to bike, bike should be able to start just fine. If it does not, the battery may have an internal short. Get a new battery.
