Ha ha, I have to laugh at the following.
My buddy said his headlight didn't work on his Aprilia.
He turned on the ignition and showed me, yep, no headlight.
On the way home it dawned on me and I texted him, that the headlight on my bike doesn't go on until the motor is started.
He texted me back after he started the motor and said, headlight works.
LOL, DOH.
He was all mad because he'd just taken it in for valve service, $1000, and he told them to check the headlight. He was going to storm down to the dealer and give them heck.
I saved him some embarrassment. I told him, all's well that ends well.
