I also have a problem with the yamaha yzf r125 2009, sometimes I increase the high revs and the speed, but if I stop with the engine running and wait and then go again, I increase the revs with difficulty or if I reach 2 dashes in the tank, it starts to stop speeding, maybe either from the throttle?
