It would be impossible to seat of pants Dyno a plug gap or type. ive got a white spot on one side spot of standArd plug every time I change out plugs. Maybe I have a shear tear of some sort from asemetrical port sizes. Have strange piston wash also. Tried diff range plugs.jetting. Powervalve spring tension.motor temp and plug gap. Still remains.
