This is all just my opinion but they all seem to vibrate to some extent at around 5k so I don't think that vibration alone is an indication of there being a problem with the bike. If you've got a drop in performance as well then yeah you've got a separate problem but I think that vibration is just a trait of that model Fazer and that it's due to something in the design of the bike rather than an indication of there being a specific problem with the bike. Cleaning carbs isn't going to get rid of that vibration. I'd say if you put a brand new set of carbs straight from the factory into your bike it'd still vibrate at around 5,000RPM so you'll probably have to live with it (or get a different bike). It doesn't bother me at all I just stay above or below 5k and that's it really problem solved :lol
