Hi, thanks for the reply, the bike misfires at all rpm above 2700, I have taken another look at the stator and it has 7 wires, it seems to have 2 source coils, a large one with a small one on top of it! The red wire from the stator is connected to the small coil but has been left disconnected in the wireing loom as there is a 6 wire CDI fitted with no red.
