Have you checked for a vacuum leak?  while it's running, spray some carb cleaner or something flammable (unlit propane torch, etc) around the carbs.  If the revs go up, you have a vacuum leak somewhere.  The CV carbs can leak even somewhere in the body of the carbs.  I only mention this because you only recently replaced the rock hard old carb boots.

It could be a problem that is only presenting itself once the bike has warmed up.
