I posted this in tech section too but here it is.... and its an 02 f4i

OK so my chain was the reason for some chirping sounds my bike was making. I haven't replaced it yet so it may be the reason for this sound too but just wanted to get some ideas....

When I hit 7500 rpm the bike starts whining. Once I get past 8500 rpm it goes away. The only way to describe the sound is when my key chain sits a certain way it will vibrate loudly until I adjust them. The sound is similar to that if it makes any sense....
