hi, MCM

I have a little problem with Qingqi motorcycle, model QM200GY-F, EFI motard version.

after ~10 minutes of ride it stalls in idle speed. mostly happened on traffic lights stops, very frustrating.
after stalling it can not easy be started by electric starter, more succes I got using kick-starter.

during 30 minutes ride (from home to work) it could happen 5-10 times, depend on luck.

only 1000 km on clock, problem appeared maybe 150-200 km ago and getting worse.

dashboard have 'FI' indicator, and after stall/restart, it indicate some error by blinking 9 times. but I can not find any relative information about blink codes of Qingqi ECU (even don't know yet which ECU they use).

anyone can help me with advice?
