KX500AF Fouled Plug Test & Cruising The Dunes, 10/20/2019

KX500AF fouled a plug yesterday. This was the first time this has ever happened! I've got it down to two possible issues. Reeds are not in the best shape or even though I had fresh fuel it may have still be tainted from the local Sinclair station down the street. Bike ran great today! I was lugging it a gear high almost trying to foul the plug but it just kept plugging along... pun intended! Lol! If it fouls a plug again the wrenches are coming out!
