R125 2012 - Battery Dead & Bike Not Starting After Jumpstarting

Discussion in 'Technical Discussions' started by Praveen, Nov 2, 2016.

  1. Hi guys,

    I am new to this channel & i own a 2012 Yamaha R125. #My bike was working fine untill the weekend where i didnt use it for 4 days. I tried starting the bike, but the battery was flat dead. I used a RAC 400 jump starter kit. It is able to give out enough charge to start the bike, but the engine gives a Big POP noise. In london weather was pretty cold and i suspect this could be an issue but i may be wrong. I am concerned that it may be a major issue. Can anyone suggest some solutions ?

    * the bike has been regularly serviced, oil is fine (10w40 MOTUL), coolant is fine.

    My bike started to pop and bang when the generator stopped working and the battery was totally drained. You could try fully charging the battery, if it drains quickly then it could be a similar problem.
