I hope you don't mind me saying this but "If the plugs spark OUTSIDE of the cylinder, then they will spark inside" that is not entirely true.
Air is considered to be an insulator up to the point that a voltage applied between two points will ionize the air and then a spark will follow that ionized track and flash over.
It takes 10,000 volts to flash over a 1cm gap at normal atmosphere pressure of 14psi or 1bar.
If the pressure is increased to 2bar then 20,000volts is needed to flash across the 1cm gap and that increases in a linear scale i.e. at 10.1 compression you need 100,000 volts to flash the 1cm gap.
You can see now why that is not always true. The fat blue spark seen at 1bar when you test a plug on the lead outside the cylinder is a good indication that it has sufficient voltage to spark inside at 10bar and also why a faint yell/red spark (which indicates low voltage) wont spark inside even though the plug gap is much smaller than 1cm.
The fuel vapor mixed with the air does change the equation but only very slightly downward by about 2%.

Well there ya are more totally useless information to clutter the brain.

In other words what your saying then is your black lead going to the 1 & 6 coil is dead. Its time to get out the book, take your manual or use the one on line here and find the the wire or lead coming from the pick up coil on the crank. The pick up coil at the crank produce's voltage and sends it to your ign. box you can read this. If you have a good digital volt meter set it to melee volts and hook the plus side of meter to wire and ground the other lead and crank the bike. the digital graph should jump across the screen if it don't pick up coil maybe be bad or there is a wire broken some where in the system. if all that works then the ign box maybe have a problem some place. it is always good to check all plug ins and wires coming from the crank up to the ign box. One other word of advice do not trust ohming the wire to make sure they are connected because you can ohm thru a bad connection but when you add a load to the wire it will fail.

WoW nice one RickG i always new it didnt work but now i know why.

knowledge is power...
