GV 125s loses power at revs (2000), in 1st and 2nd gear. Above 5000 revs it is ok. Error P0850 – GP or Clutch lever Switch Circuit Malfunction was displayed.
I corrected the contacts, the error is still there.
Can anyone help?
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 ?
At idle Does it stay 1500 rpm ? ==== > or does it do this 1500, 1700, 1400, 2000, 1500 ? Is it steady or flactuating ?
Quote It jumps gently, 1500, 1700, 200, 1700, 1500 … something like that. But on a cold engine the first 3 starts from 1 work normally, then it starts to jerk when starting, at low revs. Gas to the max and the engine barely moves, suddenly it accelerates rapidly.
