I bought an old SR model KDX which has never run right.
The engine has been re-built and the Carb. replaced but it still runs like a dog.
It is OK at low rpm and missing badly at full throttle. There is a lot of unburnt oil and fuel in the exhaust.
I have tried re-jetting and plug chop, the spark plug color is fine.
I believe the CDI may be at fault, but cannot find a replacement.
Worryingly the CDI is different from that shown on any diagrams I can find (KDX 200 89/94 manual or KDX 200 F1).
The CDI wires are:
Red + white (to stator coil)
Black
Black + yellow (to Ground)
Blue (to ignition coil and grounded by kill switch)
black + white
I have no idea what to do next.
Thanks
