on 2 strokes you have to be carefull when starting. if you give it gas when you kick it, and it doesnt start all the oil from the gas will build up on the plug and the tip will be black with build up on it, and if its ran at low rpm the same thing can happen. its just not running hard enough to burn the oil off of the plug

I HAD A YZ 50 AS A KID AND IT WAS AN AWESOME BIKE, ESPECIALLY LOOKING BACK THROUGH THE YEARS AFTER ALL THE OTHER BIKES I HAVE HAD, VERY POWERFUL. THE YZ 50 WAS THE MOST TEMPERMENTAL OF ALL Motocross BIKES I HAVE OWNED (YZ, KX, RM). YOU HAVE TO START IT AND REALLY LET IT WARM UP OR YOU WILL FOUL PLUGS EASILY IN THAT BIKE. DON'T GIVE IT MUCH GAS WHEN MARMING UP, AND LET IS RUN FOR A FEW MINUTES BEFORE RIDING. GREAT BIKE.

Black plugs indicate that you're getting too much fuel. You need to set up the carb and to do that you'll need access to an exhaust gas analyzer. Don't go too lean or you'll burn valves and possibly a piston. Running "rich" can also cause a rough idle.
