thanks Kaos

but i have charged the battery and the bike won't start

it could be the regulator-rectifier?? i have seen the voltage go up to 15v

when under charge then drop down to 13v:eek:

it seems weird and that should be related to regulator issues??

Charge the battery at 2 amps (trickle charge) or lower for at least 12 hours to 24 hours.

Battery too weak.

There should be somewhere around 13.4 without charger on it. 12v is too low.
Get a new battery, give it a slow 2amp charge for min. 12 hours, then plug n play...

A fully charged battery that has settled after charging (a couple of hours) should show 12.8v pretty consistently over days and days, perhaps even weeks. Less than 12.4v indicates a weak battery. 12v is pretty much dead as far as starting your bike is concerned.

The 999R I'm riding at the moment has a similar issue. Once it finally starts, it's showing 13.6v, but if I shut it off and restart it later, it's showing 11.2v.
New battery too..?

Make sure you are reading your running voltage at 3000 RPM or more....
