hey my sx is fouling plugs, only first thing,fine warm,, has br8s or hs in..correct but eng. has some porting so ???
they are the right plugs. I had problems with fouling and turned out to be the oil i was running. Ive found "belray" oil to be good. Yammalube is the worst (and most expensive) IMO, when I tried that I was fouling plugs almost on a daily basis
