Thought about that. Only checked one yesterday and I was busy all day today so I only checked the fuel pump.

Well,it could be the ignition module,advancer (or equivalent), also your bike probably has separate ignition coils (at least two anyway) so one plug may spark but the others don't. If you have fuel in the chamber and you have spark, the engine has no choice but to fire imho. Man you didn't wash it or something did you? I've seen water get into the "module" area (where the fuses and relays are) or into the ecu connections before and cause problems... You don't have a power commander do you? Make sure you check all of your fuses, relays and ecu connections.
