I have a 07 Kawasaki Valcon 900 classic, it only has 25,000 miles on it. new battery,not even a week old the battery only last about an hour then you'll have to jump it off the battery is dead.

Question edited for clarity.
Question moved from Cars and Trucks.

It can only be the headlight switch or the wiring.

The brake lights work from power, plus the brake switch and the lamp.

The headlights work from power to headlight switch to the headlight lamp and the tail light lamp.

Apparently the headlight does work via a relay so test that.

bent shifting fork maybe?

There is a site glass on the side of the crankcase that contains the clutch, it is about the size of a quarter, the oil should be 1/2 way up the glass hot engine.

If you have not done so, I would suggest taking the carbs out and cleaning them thoroughly. Clean all the jets, check and adjust the float level. Check your air/fuel mixture.

Back firing is typically a sign that you are running too lean.

Bad switch,Bad relay,bad solenoid the solenoid may need cleaning.
For troubleshooting remove the positive wire from the starter.
That is the biggest one. on the starter.
Now place a load on the wire say a headlight or 12 volt fan

the oil level on my 09 vulcan 900 is 3.2 liters and you check the water level under the side panel.

then your stator or regulator is bad on your bike.
