Always inspect your new spark plugs before installing. Check the gap on your replacement spark plugs with a feeler gauge. It should be set to .040 inches (1.016mm).

Questions.1 with a stage 1,2 or 3 would you agree a wider gap? 2nd question which is simular to first.i do run my motor a little rich.rather rich than lean.my question is with modification on a harley davidson sportster.what do ou recommend.so many choices from om to iridium to platinum.then the gap and also are you a believer in cutting the eledtrode approx half off for max combustion.how much would you recommend cutting and back to og question.the gap.is a larger gap.capable of power increase.since ive tried both i swear i feel a power increase.but is it anticipated or other varibles???you opinion is valued.

Reinstall your spark plug wire by pushing it firmly onto the new plug.
I have a Harley Davidson Xr1200x Sportster which I just got. Changed the oil also tranny & filter as I couldn't find last date of service coang of oil. So yesterday I checked the spark plugs they were clean. But the mechanic cleaned them & said the needed gap them as one was too narrow. Mind you I had no issues at all. Gapped them at 0.40 now I'm not getting the same smooth sound or feel as if it's miss firing. I have iridium spark plugs okn my bike should I change them to NGK or get another set of iridium spark plugs.please advise..
A spark plug Gap is to be checked with a wire feeler gauge, not a flat feeler gauge….
