Sory I am not well in English My son's bike is a 2006 Yamaha 125 R It's have an ignition problem. now we find any ignition same as magneto lighter on ignition coil's output end.But it isnt enough for ignition. This bike have a digital speedometer,I think that,speedometer not sent impulse to cdi but I seen bikes some versions havent a digital speedometer. for example Yamaha XTZ125 is same other parts. I test new ignition coil and controlled clutch censor. CDI positive pin ok,ignition positive pin ok. How many volt on igniition col's login plug? and end plug?
