When the lever is pulled, it bridges to the black (black/yellow) wire running directly to ground inside the left control. Any time the lever is pulled, it should ground the safety switch circuit, allowing both the starter circuit and the igniter to work. No, this changes the ground path for the starter relay coil between the neutral switch path to ground (light green wire) and the main harness black/yellow wire. Yellow/Green is the common wire in the diagram.

On the NewGen, the switch is wired up as single-throw (the neutral switch circuit no longer runs through the clutch switch). When the lever is pulled, the bridged connection goes down the green/white wire to the sidestand switch. For that circuit to ground, the lever has to be pulled plus the stand has to be up.

Have a look at this again: http://faq.ninja250.org/images/a/a4/...matic_-_R4.pdf


The neutral wire does go through the clutch switch but not in the way you describe it here. Every manual I've seen shows it as such. You're mixing up the color of wires and what they do.

Interesting note: According to the diagrams, you shouldn't be able to operate the starter with the clutch in, sidestand down and in gear. Haven't tested this though.
