Reply To: hi, I have a problem with service error – P0850 – GV125S / GV125-S EFi Bobber
Gear Position Sensor (Neutral Sensor) = Faulty or broken wires inside
Or
Clutch Switch handlebar has problem (actual switch or wire broken inside)
Also if there is power loss at 1000-2000 rpm = Does it idle okay in standstill or when you idle , does the RPM needle jump up & down ?
