How many miles has the bike done? Has it had a replacement chain? How much free play is there in the chain? Also are the teeth on the rear sprocket pointed or do they have nice wide flat sections at the top (as they should)?

Try putting it on the centre stand, then turn the rear wheel by hand. If you hear the noise it probably means that the sprocket is worn and needs replacing. Depending on the answers to the above questions, the chain and rear sprocket might need doing too.

Might be worth whipping the sprocket cover off and have a look at the sprocket and chain and clear the crap out from inside it, also have a look at the retaining nut and washer as these can give bother on these bikes. As Grahamm says give the wheel a spin with your hand and see if anything shows.

 This could be a few things: -
 
1. Dry chain
2. Misaligned wheels causing the chain to run out of line chain.
3. Tight spot caused by either of both of the above.
4. Loose front sprocket . 
 
If (1) is allowed to go on long enough it will bugger the chain/sprockets and you get (3) if (2) is allowed to go on long enough you get (3) if bad enough (3) will spell the end of the chain/sprockets.  (4) is not uncommon on early Fazers but very unusual on the injected normally caused by poor fitting.
