Starting glitch

[ChristoT]

Sounds like sticking clutch switch. Spray WD40 all around and into the clutch switch and see it it sorts it out.
The kill switch debate is from olden days when bikes turned over, but would not start with he kill switch off and was the reason for many mechanic call outs. Newbies were told not to use the kill switches.
It is probably the safest and quickest way to stop any bike. It prevents (as already stated) the problem of kicking it into gear when kicking the sidestand down.

I could understand a sticking clutch switch - but it's doing the reverse of what I'd expect? It's an odd 'un.
