2102 RSS fuel delivery issue
was riding on my spyder the other day when the engine started to miss and i had to pull to the side of the road. when i stopped it died. right after that it stared a few times running very rough and then wouldnt start at all. after towing it home i got it to start and run normally for a about 20 seconds using starter fluid but it still wont start on its own. seems like a fuel delivery issue to me but i have no experience with these machines and dont know where to start. also, i can hear the fuel pump running when i turn the key on, and it has fresh gas. any help would be appreciated

2102 RSS fuel delivery issue (continued)
changed fuel filter and spark plugs and bike will start and idle rough but will not rev and eventually dies at idle. with airbox cover off i can hear a coughing sound caused by air (feels like exhaust) being pushed out of a tube that goes into the airbox (egr?). every time the bike coughs, with the throttle cracked to see past the throttle plates, i can see fire in the throttle body, as if something is igniting in there. maybe a timing issue? is there a variable valve timing system that fails on these bikes? all help appreciated.
