A 6 cell battery which should be 2.2V per cell when fully charged should read 13.2 volts with no load applied, as soon as the ignition is turned on it will drop slightly, the biggest load is the starter motor so when cranking that the volts are really going to try and drop off and if pulled down to far not only do you get slow cranking of the engine but also week sparks, poor pulsing of the injectors etc and the bike doesn't want to start
Some garages can stll test a batteries condition with a load cell may be worth asking around your local ones
