Pictures would be sweat? No thanks on the sweat pictures... Gross.
Cossitt: If it doesn't start with starting fluid, you can rule out a lack of fuel issue. Now, on to the next requirements for ignition. Air and Spark would be the next step.
***WARNING:*** Attempt the following step only for a very SHORT period of time if it starts, and if it doesn't, don't continue to roll it over with no air filter! You may do PERMANENT damage to your engine (although it's quite unlikely..)
Pull your air filter and give it a good look. If it looks clogged/dirty as all get out, go ahead and bust out the ether and try to get it going without the filter. If it starts, this tells you it's your filter. If not, move on to spark plugs.

Pull your plugs. If they smell of fuel/starting fluid, they're not even popping enough to burn that small amount of stuff... If they're wet and stink, you can try the following steps... I would just replace them though. If they're black or white, replace them (you're looking for a light-brown, that's ideal).
Pull the plugs and bust out a propane mini-torch or just a lighter. Ignite your fire-maker and direct the flame towards the end of the spark plug. Work it over the whole bottom end of the threaded portion and the center/side electrode. You want to burn off any fluids that may be there. I don't know if you work like I do, but I need to know WHY something is being done, or the process seems stupid and like it shouldn't work, so here is the explanation of why: The mindset behind burning off the fluid is that the fluid may actually allow the current to "jump" from the center electrode out to the threaded body long before it reaches the end of its path and has to jump to the side electrode. If this happens, obviously you have no spark at the end of your plug, and this won't allow the bike to fire.. Make sense?
I hope I got that right. I expect criticism Spooph, so go ahead and correct what I muffed up!
Hope that gets you going Cossitt, if not your next step is to check that the plugs are actually getting spark (which I can explain in another post if need be).
Stupid question: Are you sure you have your kill switch to the center position of "Run"? Always check the simple things first!
