Sucking noise from filler cap.
#12
If you can open the filler cap when you stop to but petrol in with no problems the breather is OK.  I once accidentally kinked the breather hose putting the tank on and the next time I went for petrol the filler cap felt like it was welded shut I thought the lock  was broken even tho the key turned easily I eventually managed to get the cap starting to lift and there was a rush of air into the rank, after working out what happened I'm surprised the base of the tank wasn't bent up with the vacuum in the tank.  If your petrol pump is working OK a blocked breather isn't a problem!

What choke/throttle settings do you use for starting?  No choke, press starter and then twist throttle open to about 1/4 or 1/2 open while engine cranking over usually works unless temperature near or below freezing. Once started a little bit of choke can hold the tickover up while you put helmet gloves on but moment you start moving put choke completely off. 

My old Kawasaki needed full choke to start and some choke on for about the first mile, it took me a while to get used the Fazer not needing choke and cutting out at first set of lights if the choke was on
