If its only on 1 cyclinder and your sure the carb and sparks ok then the next step is to do a compression test to see if the fault lies with the engine, i.e. valves, rings etc,

    worth a try is that cyclinder/carb more open to bad weather if bikes on side stand

hi, each lead has the specific number on it. if you do this correctly then they genrally give you an idea to where the sit in the coils( the way they bend :-) ) also i believe the coils are better off been attached to the frame once you are sure leads are in corect order and possitioned correctly in the coils.i just presumed the coils neaded earthing. make sure battery is pleny charged as a bad battery can just hinder. it is also very easy to flood the bike so just check the plugs again. if they are unusually wet then dry them off and try again . otherwise maybe try cleaning all electics.

hope this somehow helped

This sounds more like a lean fuel condition than ignition. If it was stored over the winter without the gas being drained or a fuel stabilizer being added, you'll likely have varnish build-up in the fuel system that is not allowing sufficient fuel flow.  If your engine is fuel injected, it's likely your injector is partially clogged.  If it's carbureted, your carb jets may be partially clogged or your carb float may be sticking and not allowing the needle valve to fully open.  Fill the gas tank with fresh gasoline, but leave enough room for a can of Sea Foam.  The Sea Foam may be able to break up the deposits and allow fuel to flow again.  However, there's no guarantee and the fuel system may have to be disassembled to be cleaned.

You can check the primary and secondary resistances in the coils, dont know offhand the values, but the coils should be the same.
The fact is gets worse as it warms could mean a carb float is flooding,
The vacumn fuel tap can be a problem, this can also cause fuel to flood into the sump , and cause this problem.
