Diagnose this

[Eddie]

Ok I have a weird issue that I can't figure out. When I first get going on the bike and begin moving and fully release the clutch the bike begins to die as if I just pulled the key. If I just tap the clutch in just a few mm in it springs back to life. This continues for a few seconds or a minute but then goes away. This a faulty clutch position sensor?

Any ideas?

PS While I'm here I have another one, the bike will only run in prime, regular or reserve it gets no fuel. I checked the fuel lines and can't find a kink.

Clutch switch. Pull it and you can see the switch plunger. Squirt some light oil up there. Contact cleaner may work too, but it may also dissolve plastic. You've been warned.

Fuel petcock sounds like a vacuum issue. "Prime" is totally mechanical, the other two need vacuum. If brave, suck on the vacuum spigot and see if the petcock opens when on run or reserve (suck the fuel spigot). Best to do this on the bench with the petcock devoid of any/all residual gasoline though

Pull the plate off the petcock to reveal a labyrinth of small passages. Make sure all are open and free of foreign objects... like decomposing gasket material.

Leaky vacuum hose (or connection) to the petcock is also a possibility, the bike would kinda run like crap if this was the case.

There are safety switches for the clutch, neutral, and side-stand so you can start in neutral with the side stand down and the clutch out, etc.

In normal riding, the side-stand switch is the only one that keeps the engine going. So if you're having to tweak the clutch, it may mean the side-stand switch is not doing its job.

That's the direction I was going to go, check the sidestand switch.

If the sidestand switch is misaligned, it can cause this. Qlso check the wire routing: it could be getting crimped somewhere.
