Motorcycle Repair: Loss in power plus surging?, vacuum lines, cylinder compression

Question
I have a 1993 Honda Vfr750.  It has aftermarket exhaust, air filter, and has been jetted before. The bike has always ran rich.
Recently the bike has started to all the sudden lose power.  I doesnt run as smooth, powerful, or fast as it used to.  And at about after 7k RPM, the bike seems to be surging; surging as in bike seems to kick forward.  The bike is unable to go high speeds due to this surging.  
I've pulled the carb's out, cleaned them, check the diaphragms, spark plugs, leaked the float bowls, fuel lines, and vacuum lines to the best of my ability and have found nothing.
What should I be double checking or focusing on?
Thanks

Answer
Hi Bobby,

Describe the appearance of the spark plugs.

What is cylinder compression of each cylinder?

Was the MC stored for any period? How old is the fuel?

You've cleaned the carbs; Do you have knowledge in carburetion, or just trying to get them cleaned?

Answer these and we'll go from here.
