Yamaha '08 ybr 125 fuel pump issue .............please

Recommended Posts

Hi all

Just goined as my niece has a fuel pump issue with her ybr 125, the fuel injected 08 version. Should you hear the fuel pump prime every time you cycle the ignition as I think her's is sticking/ not moving. Every 20th time you can hear it prime and the bike will start, every other time the bike just spins over......no start. If it should prime every time has anyone got a wiring diagram so I can check the wires to the fuel pump are getting the correct feed, earth coming through.

Cheers scoobydude ( sorry I ride a street fighter gsx1100e)

Hi ,

I think I found (and downloaded) the wiring diagram for YBR 125 '07 somewhere in this forum. If you can't find it, send me a message with your e-mail address, I'll send you the file.

Hopefully it is the same as '08 version.

I would also add that I'd heartily recomended buying the Haynes manual for the ybr (it's the orange one, and also covers some XT models too I think). It gives you step by step guidance on testing wiring for a multitude of components if you have the necessary multimeter.
