In general this is the recommended troubleshooting order:
a) Compression
b) Ignition
c) Carburetion
Any other order will cost you time and money in equal measure. :pinch:
1) If the plugs are fouling with dry black soot then you have a spark problem and will need the WG Coil Repowering Mod (About $10 CAD in parts).
2) If it is fouling with oil, then you need to consider the rings or an exhaust valve seal.
3) If it is fouling with wet gas then you need to (in this order) adjust the carb bowl service fuel level, do a carb sync adjustment, adjust the gas-air ration or re-jet.
Best of success.

Sorry Bill and others, not trying to start a war here but I have seen this posted way too many times now to not reply any longer.... This wiring configuration is not truly ideal...
Does it work, yes but not without other concerns now added to your already weak electrical system. This is only band aiding a problem, not repairing it. For if in a jam and the coil voltage is indeed on the weak side (<+12Vdc) and need to just make it home while out on a road trip, hell, don't even need a relay for that....
Black sooty plugs can be some as simple as the carbs being miss-adjusted... In my case, good power at the coils but still black/sooted. Cause, miss-adjusted pilots on brand new carbs... Then there's synch and proper jetting at idle and through the ranges to contend with...
KchiefA... the advice of getting the manual, study it, and go through every check & adjustment depicted in the maintenance section and you may find it to be something normal on a 30 year old bike...
You mentioned "dragging on the track".... well that alone may be a clue where the timing is advanced or retarded or he has the carbs tweaked to perform better at mid to high rpm range or maybe, he has a hot/cold plug in there for dragging.. who knows for now until you get the manual and get busy....

However, I am interested in:
1) why you believe it is not ideal and,
2) what other concerns might be added to a weakened charging system?
I think I have a handle on the benefits and, other than the $10 CAD cost, I have not come up with any significant down sides. Of course I have only implemented this on one bike, mine, so I may be missing some details due to my small sample size.
Again, no wars, just exchanging opinions/conclusions based on research and or experience between members.
Best of success.
