Over the last few months since our Wooli AGM, the motor on my ST13 turns itself off when I come to a stop or slow down, then will come alive with a twist of the throttle. It's like someone has clicked the kill switch then turned it on again.
Other times trying to start it has resulted in surging between 1000-3000 revs and if I advance the throttle the surging still stays within that 2000 rev range.
I've had it in the workshop on several occasions, with one possible fix being to replace the battery, (which it needed in any case).
For a few weeks it behaved well, then went back to it's old cranky self.
The last time I left it there over a couple of weeks, for my mech to ride it himself and see if it would play up on him - which it did!
He thought it was the side stand switch, which when disconnected, seemed to fix it completely....for a couple of weeks.
I've since replaced the switch with a new one from Brisbane Motorcycles (https://brisbanemotorcycles.com.au) for $49. Good people to deal with and with very quick service. Two days delivered post free :thumb
One thing I've found is if I turn off the ignition, wait a couple of seconds, then turn it back on, it's good for the rest of the day.
Weird!
Having scrolled through the STOC forum, I've come across several similar cases, with varying fixes ranging from replacing the fuel pump, to replacing the side stand switch, to bypassing the lean angle sensor, to cleaning the kill switch which I'm going to try with a bit of WD40.
Has anyone else come across anything similar?

You may wish to try an ECU reset. See http://ozstoc.com/index.php?topic=11334.0 (http://ozstoc.com/index.php?topic=11334.0)
I hope someone else can shed some light on this for you, as an unreliable bike is a real bastard.

Thanks Pete. Not feeling competent enough to try this by myself, I'll ask a knowledgable mate to help and let you know how its goes.
From what I read it could well be the answer to my problems, but I should point out it did all this prior to installing the new battery which Mick the mech may have done anyway.

I would not use WD40 to clean this switch. There are some contact cleaner cans which leave no residue.

Thanks for telling me this - I've found some contact cleaners at Supercheap Auto which I'll visit tomorrow :thumbsup
