Buzzing and shaking after getting off the GPz.

I've got the dreaded "Buzz" as well. I have tried adjusting the  
valves and replaced the plugs and one bad spark plug boot and it  
hasn't got any better. I am hoping to get the carbs sync'd soon and  
maybe that will help. I got the bike in August 2005 with only 9300  
miles and now have around 17,000 miles. I wish someone could come up  
with the answer to this it really sucks and makes riding much less
