Hello I have just purchased a 2007 cbr600rr a couple days ago. When i turn the key to start on the bike, it makes a weird clicking noise while bike makes that humm noise while the fuel pump is priming. The bike starts fine its just makes a weird noise which bothers me please help!

Here is a video of it:

Sounds like an injector to me, but I could be wrong.

 

Hi. Welcome to the club! Video was very short so difficult to see the bike and determine what the noise was. Never heard it whilst starting my CBR 600 though. Sounded vaguely like a backfire, but as you say the bike starts ok, I doubt it. Make a longer video and make sure we can see the bike and repeat whatever cause the banging noise I heard at the end. Sorry I can't be of much help.
