For cold weather you need around the 200 mark. the 800 needs a 10AH battery. This will do the job: http://www.amazon.com/2004-2005-Kawasaki-Classic-Motorcycle-Performance/dp/B00688UE40

TO ALL VN1500 OWNERS....This once happen to me,
I went to the garage to start the bike "Nothing ""The first thing is the lights are bright but no turning over,Next you think the solenoid is kaput but the answer was very simple and the fix takes 30 seconds..
Do not take the bike to bits looking for other problems and look at the clutch leaver and you will see some wires going into a plastic shroud going into the switch in the clutch leaver, Make sure this has not popped out if its connection as it some times may do after a few years due to constant turning on the handlebars,
When this is not connected you will have a bike that will not fire up but comes alive and you will hear a clicking noise but this is from the engine carb area and every function of the bike will work but it will not turn over, Worth looking at and saves sixteen quid for a starter unit you never needed.

On The vulcan you can access the starter relay directly, you have 2 bolts for the power leads on the back, carefully short the two big bolts with a screw driver, this wil put power directly on the starter bypassing all. If you think that there is a problem maybee with the starter, then 1st remove the starter from the engine and do the same test outside the engine to avoid damage.

test or replace fan switch thermostat and flush cooling system

The oil bolt is in the center of the bottom of the engine. Put a tray underneath it and remove the bolt. Also unscrew the cap on the left hand side that says oil so there won't be a vacuum.

check your fuses, thenyour coil wires. not the plug ,the coil.
