Are you sure it's not the cam chains that you're hearing?

I've never heard an FZR transmission whine.

just thinking... the whine doesn't vary with engine rpm... it varies with bike speed. so I don't think it's cam chains.

What condition are your chain and sprockets in?

Is the chain properly tensioned?

Can you put the bike up on a rear stand and spin the wheel?

Could also be your rear wheel bearing going south.

wheel bearings are cheap(even the good ones from all balls) and pretty easy to swap out so lets hope thats it!

Mine has a louder 2nd gear and 6th gear whine then any of the other gears ..... well it looks like a little extra wear on those 2 gears .... After i installed a new DID chain and new sprockets , the whine was not near as bad , but it was still there ... The guy across town put a new non-sealed drive chain on his bike and said it made it whine louder then before .... Tranny design wear & tear , worn drive chain and sprockets , it's gonna whine up a storm .

Ok this will sound strange. I had a similar whine on my Z750 the was really apparent above 5000rpm. I adjusted the chain and changed the oil...no more whine. :whistle

get some loud exhaust , that whine will go away instantly. LOL anything with a gearbox is gonna whine so i would get used to it, you may try some full synthetic oil to quiet it down a little .
