Have the carburetors or throttle bodies & injectors cleaned, clean fuel lines replace all fuel, change oil to be safe.

After you start the bike put the headlight on high beam. Rev the engine and the light should get a bit brighter. If it stays the same or dims the battery is discharging.
If you have a meter, take off the seat and start the bike. Place the meter in DC Voltage mode and place the red probe on the + side of the battery and the - probe on the negative side. It should read 12v to 14v. Start the bike. The voltage should rise to over 13V or at least higher than it read when the bike is not running. If you rev the engine the voltage should also rise a 1/2 volt or so.
If the voltage remains the same or decreases you have a charging problem. Here are the two most likely fixes.
Tighten the battery connections.
The rectifier is not working. It is located on the right rear of the bike under the seat fairing.The rectifier converts the AC voltage coming out of the alternator to DC voltage which is what the battery needs to stay charged.

Definatly a good tune up would help, but it also sounds as if you may have a bad stator. I would check the voltage at the battery and see if it goes up and down when accelorating.

Two things can be happening, either your charging system isnt doin the job, or you have a short thats draining yer system... so
to answer your question... start by fully charging your battery, then put a volt meter on it and turn your bike on.... the volt reading should increase.... if it doesnt - you got a stator or regulator problem - if it does..... you need to trace your wires for a possible ground to yer frame

hi, each lead has the specific number on it. if you do this correctly then they genrally give you an idea to where the sit in the coils( the way they bend :-) ) also i believe the coils are better off been attached to the frame once you are sure leads are in corect order and possitioned correctly in the coils.i just presumed the coils neaded earthing. make sure battery is pleny charged as a bad battery can just hinder. it is also very easy to flood the bike so just check the plugs again. if they are unusually wet then dry them off and try again . otherwise maybe try cleaning all electics.
hope this somehow helped

the speed sensor next the starter motor
sends a voltage pulse to the speedometer.
If you can get at the connectors
just down from the speedo you can
check for this pulse.
Block the back wheel off the ground.
Unplug the connectors and hook
a volt meter to the pink/green +
and the green/black - wires
on the harness side not the speedo side.
Turn on the key and then
check for a 0-5 volt pulse
when you turn the wheel forward
slowly.
If you have a pulse the speed sensor
is likely okay and your speedo
circuit board is faulty.
If you get no voltage pulse then you have
to check the pulse closer to the
speed sensor or check the connectors
and wires for faults.
No pulse can be a faulty speed sensor
or just a bad connection.
Have you checked the fuses well?
