As the lifan is an ECU driven motorcycle the replacement engine would also need to come from an ECU driven one as well and also would require the ECU for the 250 engine. The ECU also controls the ignition and the fuel injection so if the 250 engine was designed for a carburettor it probably is not suited to the ECU wiring system.
