Combustion Problems

To get a fire you need three things:

• Fuel
• Air
• Spark

My motorcycle seems to lack one. :-/I haven't ridden the bike for a while and it's sat covered hooked up to a battery tender. I needed to move it so our little alley could see some traffic. I went to start it and it sputtered and died. Nothing happened after that.I can smell gas so I'm figuring it has fuel. I checked the air filter and that's clean as a whistle. I had a thought that the plugs could've been fouled by the gas as I was cranking it so I swapped those out with a spare set. (I have to admit the bottom plugs were a bit crusty) Held up I can see a spark so it's not likely to be that.Boo... I think I have to get the poor beast trailered to a shop here. It's annoying since i take pride in the fact I can fix stuff. To not be able to fix this is a pisser.The only thing I can think of is a fuel pump or filter issue... Beyond that I really don't know. Everything else should be good.
