Bike won't start. Possibly fuel pump?

-What I'm currently experiencing is the bike will start only if I spray in throttle body cleaner, it'll stay on for a few seconds then die unless I roll on the throttle...
-Edit-
Regarding the Seafoam, my brother doesn't recommend pouring it directly through the throttle body. Just to be safe, put it in your gas or get it in through one of the vacuum hoses. I guess putting in such a concentrated supply directly to the source isn't too good of an idea.

sounds like for some reason you arent getting enough fuel. when you emptied out your fuel tank did you pull the fuel pump out ? i remember once we changed the fuel pump on my brothers sierra truck and my friend wired it back up wrong so the fuel pump was pushing instead of pulling and it wouldnt start . so even though you hear the fuel pump maybe something is wrong.. pinched gas line or something

Hmmmm.... I doubt that's the issue since I didn't pull out the pump. Unfortunately I won't be able to look at it again until the weekend comes again though. Hopefully I can get this figured out. I'll update/ask more questions when I get the chance. Thanks to everybody for their input though.

I suffered the same issue when i had the bike parked for three months. So far you've done the right things... fuel change, throttle body spray, and spark plugs.
When you changed the fuel, there is still the old fuel in the lines. What i did was to continue cranking in 10 - 15 second bursts at wide open throttle to flush out all the old fuel, let it rest for about 15 - 30 seconds. The more you crank it, the longer you should let it rest. Eventually the bike fired up after going back and forth for about 30 minutes. Lots of black sooth when it did start.
In addition, I hooked the battery up to a car as the bikes battery will not sustain that cranking for that long. When the jump cables heat up, disconnect them and wait a while for them to cool down.
I don't think you need to buy or change anything, these engines are bullet proof.
Hope that helps.

Short bursts is the key, and then give it some rest. When you crank non stop, it starts to overheat.
I'm sure there is a way to completely drain out all the fuel in the lines, the throttle bodies, the injectors and all, I just don't know how to do that. So for me its just ensuring that it all gets flushed out.
Goodluck and lets know how it goes.
