Default weird rattling noise

hey guys. my bike (02 f4i) is making a weird rattling noise. it sounds like a metal on metal kind of rattling. it happens at idle and while riding. even after i shut the bike off it rattles for a couple more seconds. when it rattles after the engine is shut down it sounds like its coming from the exhaust, but while idling it sounds like its coming from somewhere on the left side. i have a yoshi rs3 slip on. i also replaced the stator cover last year so ill check to make sure the bolts haven't come loose on me or something. is there anything else i should look/check for? thanks for any input.

remove your exaust and give it a good saking... Could be you ave somethin in it or that your packing has come loose and ur baffle is rattling... If it's not that then go from there but tats wat ide start with...

I think I had this problem on my F4i before too. At least the rattling sound when it's off. I've heard that sound for other bikes too so I figured it wasn't a big problem. As for the rattling when you're riding...my guess is the cct lol. That rattling when the bike is off, that I hear, would be too quite to hear while riding. When you say left, do you mean left side when on you're on the bike? Or facing the front of the bike?

There are ONLY 2 things that could make noises after it's off....

1. If you done the air box mod, a few seconds after shutdown you'll hear a buzz that sounds like air escaping a valve. mine did this for about a year after the mod then just stopped, or ateast got so quiet i couldnt hear it anymore

2. If it's over ~225 degrees the fans will run for a few seconds after shutdown (with keys still in)

Am i missing anything?

so i noticed today that if i have my bike leaning to the left, the rattling is from the left side, and if i lean it to the right, the noise comes from the right side. if i stand the bike straight up, the noise is practically gone. does anyone know what this might be, or could it just be a rock or something vibrating around. i do get a lot of vibration from my bike and get numb fingers during long rides.
