Thanks Jakobi, never miss out...
another quistion- the motor tend to die very fast.
I must to keep the throttle a little open with pulled clutch in order to keep the motor alive.
if I increase RPM with the idle screw its affecting only when standing.
once I start riding the the motor is sensitive to switch off again.
the bike is ec300 2011, 42 NEDJ#3 175
2 turn out AS.
