Hi,
Some of you may remember that I was having a starting issue a while back. Rebuilt the starter, cleaned all the grounds, replaced the battery. In the end it turned out to be a clutch bolt that had backed out and was dragging and then stopped the fly wheel from turning. New clutch and everything has been great. I also installed a voltmeter so I can monitor my battery and charging.
It has been starting perfectly every time until until yesterday. It usually fires right up. After ridding for a bit if I shut it off and go to restart it will click I think once then not turn over. After a few pushes on the starter button it fires right up? It seems like perhaps the starer switch is not making contact or dirty. I have not checked the other wires for tightness yet but since I just rebuilt the starter I'm guessing they are good. Does the starter button fail or need to be cleaned? If so how?
Thanks! I like it better when I'm confident my bike will start.

What does the volt meter say when the starter clicks. A small drop in voltage would signal starter switch, solenoid, a big drop could be a dirty terminal. In between drop could be a starter jam.

The starter button is powering a starter relay
remove the seat and touch the starter relay and if you feel it clicking then the starter button is fine
I quick check for battery positive on the small black wire on the starter when trying to crank will tell you if the starter is getting a signal
If it is your starter is more than likely bad
If it isn't getting a signal and the relay is clicking then the relay is bad
But of course a dirty connection anywhere along the circuit can also cause all of this
If you just want my gut feeling on this it sounds like your starter is going bad ;)

No offense intended Raphski but if you've installed a voltmeter I'd double check that.

No offense taken, I'm always good for advice. I have not had a chance to trouble shoot further. I have been ridding most days and it has not not started or left me stranded yet. I don't think it's the voltmeter as that was in for a few weeks and caused no trouble. Your comment did remind me that I recently added new horns with some wiring work. Previously the old honker factory horn was powered with a non factory wire from the ignition switch to the relay then to the horn. As suggested I ran a wire directly from the battery through a inline fuse to the relay and then to the two new horns. I will double check that wiring as it was the last electrical work I did.

Especially the battery terminal.
