while you're sorting out all your woe's, go to a softer plug. put a 7 in it. the trouble is, you can't sort your problems if you can't get it running first. right?

remember when you finally get it running sweet. this plug won't like hot days & lots of WOT for miles.

The bike has a pumper carb. This means it has an accelerator pump in the carb just like a car. You cannot turn the throttle if the motor is not running. It will flood the bike and foul plugs.

You really need to provide details on when and how the plug fouls, under what conditions, temperatures, elevation. Your problem can be solved. It has been many times before on this web site. Just provide detailed info and wait for the responses.

So I would suggest you take the carb off and look at the pilot, main and needle jets. Also screw in the air screw in the bottom of the carb. Make sure you keep track of how many turns it is. Record what is being used and give more info as outlined above.

Oh and do not run the choke for more than 20 seconds. WR's don't like a rich condition for very long.
