Starter self engaged...
09/17/16 at 16:20:59

I started it,.. it was running for about 3 seconds, and the starter re-engaged (all by itself)... (a loud metallic clack, followed by the starter motor running)
... it ran for about 3 or 4 seconds with the engine already running then disengaged.
YIKES!...

I have heard a clank followed by a starter whir, 2 or 3 times in the past few weeks... but, this time the starter really ran...

Sooooo... starter button sticky?,.. relay under seat?... or solenoid?...
Any idears?... Huh

PS// 'till I get it figured out, I have the pet shut off, and have disconnected the power to the starter...
..(I don't want it driving off without me)... Grin

Please don't let it be the starter clutch... ....PLEASE... Huh

Reply #2 - 09/17/16 at 18:15:07 most likely decomp controller. but if you want to eliminate faulty button, put a 12v led light on the clutch safety either wire, to ground. use an led cause they don't draw much current. anytime you use the starter button, that light will light.

most likely decomp controller.

Considering a temporary bypass of the de-comp,... but...
How would a failing de-comp cause the starter to engage?... (wouldn't it have to receive juice from the starter button?)...

Just askin',.. hope I'm wrong really... Huh

Clymers shows how to test the dcomp controller on page 245. But, you have an intermittent issue with the dcomp starting the complete cycle on it's own.
Do you remember if the clutch was pulled in at the time it acted goofy?
If so, the starter switch is acting like it is pushed, when it ain't. OR, you have something else that is putting voltage on that line.

That's more what I was thinking...
(dcomp wouldn't trigger the starter without juice from the starter button,... and starter relay sticking wouldn't trigger the dcomp, only the starter)...
Clutch cut-out has been bypassed for years...

So,.. I just took the starter switch apart, and cleaned the contacts.
Tested it with the starter hot disconnected, and it seems to trigger the dcomp and starter relay consistently.
I put it all back together, and I guess I'll just have to ride it for while.
...(carrying a 10mm just in case I have to disconnect the starter hot).. Grin

It has happened at least twice. Middle of the night and the savage dreams of riding just like a dog dreaming of chasing squirrels.

Maybe they had a flaky starter button... don't know.
BUT, the decomp controller has power to it all the time.
What I'd do is redo the power wire to the decomp and put it thru the ig switch.

That branch does more than just power the decomp, I'll have to look at it later.

Standing behind the bike, I wanna say the second wire from the left, you put 12 volts to it and it cranks over, even if the key is in your pocket. Make sure nothing is accidentally doing it.
I put a switch on the hot wire right next to it, and used a membrane switch from a dead dvd player. It's a very low amperage thing. Find out which wire will crank it, then be sure nothing is accidentally doing it.

My screen won't let me read the How to test the decompression controller.
All I have to offer is what I posted. Mine, when still pretty new, would just Die, and no matter what I did, it would not spin over.
After ten minutes or so, back in business. Never figured it out, but by putting the switch on the wire on the decompression controller I could make it go again. So I Know there is a wire that spins the starter and the current required to kick it is so minimal that a membrane switch, small enough to sit on the nail on my pinky will handle it. That tiny switch got used quite a few times and never failed. It was slipped into the finger of a rubber glove and tie wrapped up under the frame. There's a red wire, 16/18 gauge with 12 volts Always on it, right next to the controller. Could be your problem if it's laying over and rubbed a bit.

Reply #14 - 09/22/16 at 14:56:55 Pretty good description of the safety system. I'm planning of removing the decomp controller. So, if you short 2 to 4 on the wiring harness, the starter button activates the starter directly w/out the decomp controller.
