fouling a plug with a 4 stroke?? what wrong?
my 83 and 84 big reds had their origional plugs untill '97, when i decided to change plugs for the heck of it. that was a mistake. i couldn't get more then 3 days of ridiong before the plug would crack, foul, or make it hard to start. after going though a lot of NGK plugs, i switched to champion. no problems since. still have those champions in there. also, my arctic cat 500 fouled it's plug in the first 200 miles. my dealer gave me a new plug, and that one has held up and now has 2000 miles on it.
