2004 Kawasaki Vulcan 1500 classic = part # 764585

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.

7-8 mm

New Clutches should be approx 130 and up.
A shop will charge 150 and up to change them.
So $280 and up for that model, and depending on the labor rate.

You have a wheel that is out of balance

hi buddy the standard size is 150/80-H16 thats the only size you can have

correct setting for your plugs 0.8-0.9mm

read the tires..duh

Without more information, my guess is I would clean your battery cables, most important one is the ground cable under the bike just in front of the rear tire.  Also how old is your battery.
