250-500cc Universal key ignition switch

OK so i bought one of those universal duel sport key ignition switches that supposedly wires into kill switch. Problem is there where no instructions. Just 4 wires-lol. Theres a black wire, black and white wire, green and red wire. Any clue what goes where?

One of those pairs of wires will probably be normally open and one normally closed.

When it's in the off position one of the pairs breaks the connection to the lights circuit and the other pair shorts out the stator coil that drives the ignition coil.

I see your model has a cdi. Does it have full lights and speedo or just a stop switch? In the manual there are 2 diagrams. One that says usa excluded and one with no lights.

As you can see on attached diagram the one with lights the line coming out of the cdi going to the main switch control marked W-R is the engine stop line from the cdi. As you can see it goes through the engine kill switch to B. Which is chassis ground.

Manual says B is blue, W is white and R is grey. But it also says Gr is grey so who the heck knows.

You just need to find the wire going from the cdi to your engine kill switch and connect your switch to that wire and the other wire to ground.

To find which 2 wires use a multimeter or a tester. Or you could just hook up one set of wires and see if it starts with the switch in the off position.
