lus1: on the Seafoam..... I'd run some Seafoam through them if it does run after the plugs.
also, these bikes are known for being next to impossible to start if the plugs get fouled. i bet it will fire right up after you get the new plugs in.
on top of draining out the old fuel for new fuel and the plugs, i would also do a oil/oil filter change, new air filter, rad flush (make sure you use non silicate containing antifreeze when you refill). giving the entire bike a once over wouldn't hurt either. bringing back a bike from 2 years of storage typically isnt that hard to do assuming it was kept indoors, but its allways a good idea to start with fresh fluids so you at least know where everything is at.
