Need some advice please.... 
 
I bought this bike from a friend of mine...He barely rode it and for the past year and a half he hasn't started it.  I went to go work on it yesterday and the engine will not kick over. 
 
i sprayed Starting Fluid in the Air Filter and she turned over for about 5 Seconds before shutting off.  I feel like its a fuel issue.   
 
vaccum seemed good going from the engine to the fuel pump...however the flow from the fuel pump to the carbs seems week.  it did not change when i tried to start the engine...the flow stayed constant, there was no "squirt" of the gas. 
 
before i go ripping off the fuel pump or the carbs, i want to know if anyone has had this experience with these bikes.  the bike only has 3,400 miles on it!   
 
what is the most simple approach to troubleshoot this problem: 
  1.  take off fuel pump - either get a new one or clean existing one (if possible) 
  2.  clean carbs and see where she goes from there. 
 
thanks, 
  any help or diagrams would be most appreciated
