It is normal for the fuel injection pump to run when you turn the key. It is pressurizing the system. Stock, I do recall that it goes off after a few seconds. And I also recall that some were reporting that some aftermarket ECU changes would cause the fuel pump to run continuously before starting.
The S1000RR has a closed-loop prime and is active as long as the key is on. This is unlike most jap bikes which stop priming after the first few seconds.
