I just bought an '01 CBR600F4i and today when I started it up the "FI" light blinked a few times then stayed on the entire ride, there would also be a rattling up front between 4 and 6 thousand rpms, does that have to do with the injectors? I don't have the manual and was wondering if this means they just need to be cleaned or what but I would apreciate any advice on what this means and how to fix it, diagrams would be great to. Thanks.

 

Welcome to CBRF, RedWing!
You probably want to post this question over in the F4i section. You'll get much better exposure over there.

You can probably also get a manual over in the gen tech section in this thread.... HERE.

Good luck, and welcome aboard!
