I hope someone can help me, I have recently bought a 2003 650 with 19,000 on the clock....it ran lovely for a few days and the the FI light started to come on........but bike still ran fine.
The other morning I stopped the bike after a short trip and wasn't able to start it again it seemed as if the battery was flat...I put a new battery on and the bike started fine but again the FI light came back on.........I have the code C50 coming up......
Also on checking the charging it seems to be able to go no higher than 12.30 when I rev the bike.
Any help would be great this is my wife's first burgman 650 and she is not impressed at the moment.

Please please if anyone has any information as to what it might be and where to start looking I would be very grateful
Thank you

It's a loss of communication code with the CVT controller. It could be voltage, wiring connections/short/open, or trans controller. As far as riding it I'm not sure, the CVT has it's controller and the engine has it own but I'm not sure if information for operation is shared between the two or it's just for sending error codes.

Thank you for your quick reply its funny you say about voltage because the battery is only getting 12.3 volts across the terminals on my volt meter and that is at 4000 rpm,I'm in the process of taken of Tupperware and testing the stator for out put voltage then I will check the rectifier ,could you tell me if I need a new stator which is £58:00 over here in the uk that's a pattern one,can I remove it with the engine in the frame cheers for any info :shock:

It's possible the voltage could be it but most 12V electronics can work down to 10 volts or so. I would however fix the non charging issue first just in case. If you don't have a factory service manual I would as suggested already to get one, it can be very helpful as well as save you money for sure. Most charging issues have been the regulator/rectifier unit but a stator is possible. I'm not sure about replacing the stator because I haven't had to do so yet but I think with enough of the body panels off you should be able to replaced it in the bike. Best if someone who may have done it before to post up.
