I have a 2014 YBR 125 and have just had it fixed because there was no power getting to the dash or ignition, despite the battery being fully charged and ok (apparently it was a dry joint in the wiring!?). However, after getting it fixed and starting it a few times, when I try to start it now, it just spins electrically (figure of speech) but doesn't kick into life. I then get the engine management light giving 1 long flash and 9 short flashes, which I am told is error code 19. Can anyone give me any advice on how to fix this problem please?   

There are loads of sites out there that give you the code readouts yours is ;- Fault code 19 - No signal from ignition to ecu. So check the wiring from the ignition to the ECU and see if you have a broken or rusty joint.

Many thanks for the advice, I'll give it a try.
