Is there fuel in the carb? Unscrew the drain screw at the bottom (side access) and see if anything remotely like gas dribbles out (if it's not fresh, it's 10 year old sludge).
Does it fire at all? Listen to it kicking over without the electrics on, and then kick it over with. If the mix explodes up for a rev or two, you're getting somewhere.
Does it fire any differently with or without choke?
Does it fire differently with or without 1/4 to 1/2 throttle?
Look under the carb and you will see a screw in a protruding post. Screw it in, counting the turns. Then try to kick it over with the screw out 0 turns all the way to 3 turns. Any difference in how it reacts?
If it does not respond differently to ANY of the above tricks (shotgun approach to trying different air/fuel ratios), you need to pull the carb and clean it out. Old fuel will rot the rubber gaskets, clog the jets, and otherwise wreak havoc if not drained from the carb when the bike is put in storage. Also, you can try disconnecting the decompression cable and see if it can't be kicked over. Without decompression, you should have a nearly immobile kickstarter lever once you hit TDC.
