Hi guys

I just replaced the motor, as result of breaking the case,

Since I mounted the new motor I can not getting start it.

when I am trying to start the starter running for ~3 second then stop for ~2 second then again and again.... (I am pushing the starter switch continually)

I notice ABS light flash and ASR too.

I worked very clean & solid, SO, I am 100% that all component and plugs are connected,
I am using the original CDi with the original key fob, the only new electric component is the stator

Thanks in advance
Nir

before everything worked well

Since you didn't give any details we are just gonna have to guess.

What about the throttle body? The immobilizer is integrated into the throttle body on the newer MP3 bikes.

If this is the case and you did not reuse the throttle body from the old engine then the immobilizer is most likely the cause.

thanks for replay.

I am using all electronics parts form the old working original motor, include: starter, ecu, lamda sensor, temperature sensor, injector, rear sensor and also throttle.

the only new component is the stator generator.

it looks like normal behavior of the ECU that trying to indicate about ABS or other issue.

Finally, after 5 hours of investigation I found the problem.

the failure is the "speed motor sensor"
Locate in the engine case just near the stator generator.
