ngk is the best damn plug out there for a 2 stroke. champion is the worste plug ever made, i put a set in my 25hp johnson on the john boat becasue its all autozone had and they laster 1 day of fishing. autolights are not as bad but not as good as an ngk. ngks last forever in those old loop charged 2 stroke outboards. trust me, iv been through them all, ngk for the 2 strokes/small engines, and acdelco for the truck.
the bike does have an ngk and its brand new, but iv had many brand new parts fail me before so ill swap it and check my compression. that'd be pretty damn funny if it was the spark plug. maybe a split plug wire even, i have a big roll of 7mm plug wire but im not sure if the blaster requires a resistor type wire or not, it must becasue the plug is a non resistor plug. i could use non resistor wire and just use a resistor plug too.
