Only Running on 2 cylinders ? FIXED.

Hi Fellas My GT750 A model , is giving me some trouble , i went to the ponderosa cafe with Richard yesterday and my kettle performed great till on the way home , it went on to 2 cylinders , i could hear it popping and backfiring like it wanted to chime back in on 3 but never did, i stopped at charnock richard and had a quick check but couldn't find anything obvious and the bike was ticking over ok , i set off up the slip road and it started misfiring and went back on to 2 again, i made it home like this ,
i had a quick look last night and the offending cylinder is the right hand side one when your sat on the bike , i had a spark at the plug but didn't really take a lot of notice how good it was ? , i took of the points cover and noticed that the set of points for that cylinder were sparking so i presumed it was a condensor failing ?
today i changed the condenser and there was no change still on 2 cylinders but no sparks at the points , and no spark at the plug ?
i have taken the left hand cylinder plug cap and plug that are working ok and tried them on the right hand side cylinder no change ? , i have tried the right hand plug cap and plug and they work great on the left hand cylinder ? , i also took the tank off and checked all the wiring connections they are all ok ,
i checked for power to the points plate with a small test light and i connected the crocodile clip to one of the mounting screws and with the ignition on i had power to all 3 sets of points,
am i right in thinking after all these tests its probably a coil that was and has failed ? looking forward to any suggestions ? cheers Mick
