Pv tri z spark plug

Do you use the yz plug or the tri z plug. I tried the plug that is recommended for the 86 yz but it keeps fouling it. The one for the tri z seems to be ok in it. What do you guys use? Don’t shoot me if this has been discussed

Without experience in your particular situation, it seems logical to run the sparkplug specified by whatever ignition system your using. YZ ignition = YZ sparkplug. Tri-Z ignition = Tri-Z sparkplug, but you’ve probably already come to this conclusion.
