don't do your cbt on the RS.

Hire their scooter.

If you fall off, then oh well it's their scooter. You don't have to concentrate on gears and the turing circle of the RS is shite so you will struggle with the U-turn.

I would guess that the white is the power circuit and should connect to the regulator - Use a multimeter to check continuity through the stator to ground to give you some confidence that I'm guessing right. Expect a low resistance, but not a dead short.

Green is used throughout the bike for earth, so try measuring one of the other three wires to see if goes directly to ground. If it does, connect to the CDI where you'd normally connect the green.

No idea about the other two though, and what I've posted might be wrong.

i have put the wires in every possible order in the cdi, but it is still not giving a spark from the plugs, i no the spark plugs worked because they worked in the older engine.
