09 Ninja 650R Won't Start!

So here's the scoop I have a 2009 Kawasaki Ninja 650R. The bike has an aftermarket Two Brothers Racing slip on exhaust. As i've been riding the bike over the past 2 months I've noticed quite a few backfires but mostly on deceleration/downshifting or upshifting. The other day I rode to get coffee, when I came out to leave I started my bike and it died in about 3 seconds. Upon trying to restart the bike it would just turn over but not fire. I got it started and and drove down the road and it died again and would not restart. While pushing it home i would stop every so often and try to start it, it would just turn over and sometimes backfire. The next day i tried to start it and it backfired very very loudly so I stopped. The FI light comes on when im trying to start it as well. Since then I have replaced both spark plugs, I also checked the battery which reads 12.2V and I even put the battery in my other bike and it started it fine. Ill post a link to a video showing exactly what the bike is doing while it sits now. Also i might as well mention that after quite a few attempts of turning it over you can start to smell gas. Checked for leaks and see none. Any ideas/suggestions would be greatly appreciated!

If after initial key on, FI light does not go out after a few seconds, there is a stored error code which will have to be retrieved.

The FI light does go out.

The next step would be to check for spark.

Check the throttle bodies to make sure they're not out of the boots. Seen a few of them that a good backfire will pop the throttles out of the rubber intake manifold; and will also throw a code for the inlet air pressure sensor. Have you checked the codes yet?

Been there, done that on these. Put a set of spark plugs in it and go ride. Keep spares. They are known to foul a plug or two, especially with aftermarket exhaust-for whatever reason.
