Power valve not working

[yowie05]

Thx for replies. Iv spent more time working on this bike than actually enjoying the feel of it on the trails.
My feeling is that it?s the ignition coil breaking down. I?m sure the earth of everything?s ng is fine as I had been chasing a spark issue for ages so I have cleaned/replaced all connections and earth attaching locations. Befriend re the stator was replaced it wasn?t breaking down at revs but now tha the stator is really pumping voltage out I guess the ignition coil could be failing? Any chance the CDI would be failing at high revs? I?ll be replacing the ignition coil in the morning so hopefully is going t fix the issue and then can ride the beast.

So far I?ve rebuilt forks, shock, new barrel, new S3 high comp head, piston/rings, new boysen carbon fibre reeds, brakes and the stator. As spares I have an ignition coil and a cdi based on the RM I think as when it was installed it didn?t want to run at all just backfire. They need to be retarded by about 6degrees according to reading this forum.
