Thank you,
Initially, the FI indicator remained constantly illuminated without blinking, indicating a problem with the ECU unit. Subsequently, I replaced it with the ECU unit from another motorcycle, which resolved the issue, allowing the engine to start and the FI light to turn off. However, upon starting to move, the engine became weak, accompanied by random blinking of the FI light. Despite attempts to accelerate, the RPM did not exceed 2000 and trying to turn off as if there were no fuel. The attached image shows the motorcycle from which I borrowed the ECU unit.
I'll post a photo for the ECU being used later .
This ECU unit is downloaded from the internet but mine is similar to this
