An old dodge if you suspect lack of, or bad fuel, in the engine inlet is to sprinkle petrol or alcohol or starting fluid on the air filter (don't overdo it).
(1) If the engine starts and runs for a minute or so, you know there is a problem with the fuel/air.
(2) If the engine starts and then, after a minute or so, runs fairly normally, you know that the fuel/air mixture at start up is not sufficiently rich for starting (choke).
(3) If the engine will not start you know that the core problem is not the start fuel/air.
(Note that I have no actual experience with the FZS 1000)
