Hello friends to all, you see someone can guide me I have a Honda CBR 600RR 2005 and the problem is changing the engine but never touches the electrical system but when I put the new engine and I say to turn on the motorcycle it does not start it gives me a message on the board board I have consulted the manual and I have done everything as, I saw the turnover sensor, check that all the sensors are well Gasoline is good, the gasoline pump does not turn on when I put the key it seems that the EMC (ECU, or Cenralita) does not send the signal but I tried it on another motorcycle and there if you turn on ... I will thank if anyone knows about it and helps me.
