Could be relay, but are you sure you have the thing in neutral, clutch in, kill switch on "ON".  Could be your starter solinoid or however you spell it hehe.

Pretty sure....everythings ok. neutral light on, clutch in, kickstand up....all I hear is that freaking click and buzz...

New battery doesn't mean good battery.

If the sidestand and clutch switches were messed up, you'd get nothin.

You can jump the terminals of the starter relay with a screwedriver to see if there is enough juice in the battery to turn the starter.

If the starter works by jumping the terminals, chances are you have a bad relay.

If the main fuse pops when you are using the starter button the bike, it is probably a bad starter.

Jumping it with a car battery (car NOT running) might be an easier way to check the same thing.

I suspect that your battery doesn't have enough charge to turn the starter motor. The clicking buzzing sound you hear is the starter relay opening and closing very rapidly which is what it does when the battery is good enough to open the relay but NOT turn the starter.

If the battery is that new the charging system on the bike may not be charging the battery while you ride.

If it starts like normal, then your battery or charging system is at fault.

If it doesn't start and does the same thing, then the relay is most likely bad.

So, I jumped the battery with the car and it started easily....went out for a 20 minutes ride and everything seemed ok (lights, horn, etc). Get home, and tried to start the bike 20 minutes after and again the battery was dead.

Any ideas?? this is making me crazy....

Is it a sealed battery or is it one that needs water?

the stator is probably bad.  I think that is what they call it, anyways, it like the alternator for your car; it recharges your battery while you ride.  Albeit, that is your problem. Result to the manual on how to change it, or ask the human manual Kerry, hehe  

If you want to test your stator / recitifier / regulator, see the diagrams and text from the Haynes manual that I link to in the old thread
Charging system
