  1. hi just got a 2010 yzf r125 and i have a problem,when starting from cold it is really hard to start and when started it wants to stall so you have to keep it running by twisting the throttle and then it miss fires and doesnt rev out cleenly until its warmed up then its fine no rattles or nasty sounds any ideas thanks in advance andrew

  2. Just a thought..........have you checked the lead to the spark plug with it miss firing thats where id start.
