Starting prolem after changing 'bars.

[andreis]

Hi all!
Yet another curvy problem here...
I have recently done a bar mod by way of which I have replaced the clipons on my 650S ('00) with proper bars to get a better position..
It shortly developed a strange problem.. It wouldn't always try to fire up when I press the starter button. It seems that opening/closing the starter circuit (the red on/off button) and trying a couple of times eventualy gets the job done and it fires up on the first time it actually attempts to.
Seems like there would be a loose contact somewhere, but I can't seem to find it.
I have rechecked the contacts around the controls, but they all seem fine...
There is no blown fuse, as then it wouldn't try firing up at all.

How would I go about checking if the clutch sensor says that it's fine to fire up?
Any ideas in general?

Clutch switch is the first place I'd look, as with anything that's been disturbed it's the obvious place to go back to, if you have a Curvy you can bypass the switch to obviate the problem - but don't forget the bike will now start in gear and lurch forward.

Dirty starter button contacts are not uncommon too.

Bridge the clutch switch to test if it's that. I usually just stick a bit of wire in the 2 female plugs.
