we could have the same problem,looks like you`ve covered everything in the carbs and the remote fuel supply has ruled out pump,filter and breather pipes,you have gone one step further than me with the checks on the coils,these things rarely fail,iam at a standstill with mine until the needle jet arrives,if this does not work ,ill be making further checks.....did you check the needle jets when you had the carbs apart ? sounds like your down on power all round and not just on one cylinder or could it be running on 2 and have a dodgy coil thats not showing up on your test ?.................thinking aloud,not much help,i give it some more thought....dont let it get you down 
One, is never going to be enough.....
