Only starts in neutral with CLUTCH OUT

So it seems my bike has gotten kind of moody lately and won't start unless it's in neutral and the clutch is out. Any other variance and nothing happens. I've checked the plunger on the side kickstand and it seems to be free and operating normally. What else should I be checking?

Ditto on the wiring to the above. Also, does it die ?r can you ride after it starts? Does the position of the handlebars change anything. You may want to check the connections behind the reflector on the left side. You may want to check all of the ground connections as long as you are down.

If I'm reading that correctly, it sounds like the switch on the clutch lever is working backward from what it should. Seems impossible though.

You're saying you have to let go of the clutch lever in order to start the engine?

If all else fails, I know a simple wiring bypass that disables those switches and also heads off a couple other potential problems.

Well I haven't made any changes lately to my bike recently when this started and it was sporadic until now. I had forgotten about that electronic switch on the under side of the clutch. It does seem as though that plunger is sticking and I have lubricated it. It will now start in any gear or neutral with clutch in. Btw, when I said it wouldn't start, I was 1) turning ignition on 2) pulling in clutch 3) hitting the start button... and nothing would happen. I thought it was weird, hopefully problem solved.

Your posts are some-what confusing but I think you solved the problem. A refresher of the start circuit..
ignition switch, neutral switch, clutch lever switch and side stand switch.
To start engine, one of the following circuits has to be completed.
-engine in neutral, side stand up ( use of the clutch does not matter )
-engine in neutral, side stand down ( use of the clutch does not matter )
-engine in gear, clutch held in and side stand up ( the engine will start with the side stand down but the clutch lever switch will kill the engine once clutch is left out)

so to paraphrase... to START (not ride away) one of the follow MUST be true...

transmission in neutral
or
clutch lever pulled.

side stand switch only affects drive off.

Thank you all for the helpful reminders. In my confusion to solve the problem, I mentioned the kickstand sensor since that was the only cutoff switch I was aware of and encountered before, I had forgotten about the clutch switch. With all the hills here in Seattle, I regularly park in gear so as to not roll away. For me it's just habit to start in gear then take off. Thanks for the help.

Not going to go so far as recommending it, but I removed both the clutch and sidestand nanny switches from my bike when new. Not only did I find them insulting, but they do tend to fail and leave you stranded. Many people would not even ride a Vulcan 750 because it does not have computerized ABS and traction control.

I am a motorcyclist, NOT a biker.
