I used the bike a week ago went to go out on it to day and nothing no spark at all.checked every thing that I no that's not a lot took it to a mate and he thinks it is the stater plate he put some meter on to it has anybody had this problem and all so when the fan comes on and I rev it the fan speeds up is this the norm all help much appreciated.

only had 1 stator go . the plug on the module next to the engine corrodes ,is this all ok

Ya that's all clean been through it all did put the meater on the stater and got nothing so I hope it's that

sounds like it , west country windings in harlow will help

Found out the pulse sensor was not working so new one from bvm and of to Wales in the morning for a day out riding
