Hi, im wondering if someone could give me some advice, i recently bought a yamaha ybr 125 as a non runner, i found that there was no spark so i checked the coil pack which seems to be ok and the side stand kill switch which again is ok. I then noticed that when i put the ignition on the engine management light doesn't come on at all. I've just replaced the CDI with a second hand one but its still the same, any advice what to do next? cheers john 

 I think that be a plug in and clear faults john,..
