my bike doesnt cut out when the sidestand is left down? because sometimes i ride off without flicking it up, and nothing happens..
Engine Not Cranking, or Stalling when put in Gear...
[align=center]Sidestand, Clutch and Neutral Switch Wiring[/align]
If the engine won't crank or the engine stalls when put in gear, then this post might help.
The circuit below is a simplifed (and untangled) extract from the CBR250RR wiring diagram. It is much easier to see whats happening and how each of the signals relate to each other when isolated from the rest of the wiring.

STARTING THE BIKE
To start the bike, the starter relay must have a ground path to work. It can get this if the bike is in neutral. Otherwise, the sidestand must be up and the clutch in to start it when in gear. You can see these two paths on the circuit above.
RIDING THE BIKE
The CDI needs to see ground on the G/W wire, otherwise it will stop ignition events. That means the side stand must be in the up position. If the engine cuts out when put in gear, its probably the sidestand switch and associated circuit thats faulty.
If the clutch diode fails you can get weird results. Like the neutral light coming on with the side stand down and the clutch in, through to the neutral light not working. If you need to find it for replacement or testing, it's located on the wiring harness behind the air box.

Give it time... eventually it will fail completely
I wish your mad skillz could be applied to all bikes Eclipze
I wish I had one of every bike to play with In an ideal world I'm filthy rich and have my own bar in the workshop with Gunniess on tap too... but reality is a biatch.
Either way... I have plenty of wiring diagrams for various bikes. Pretty rare to find the wiring diagrams for some of the later model bikes though.
