Whos played around with gaps? i found when i pulled the sp out they were 0.055inches, i reduced the gap to be within harley specifications, 0.038 -0.043inches, so set at 0.043. I found that I lost power. Gapped them back to .055 power returned.
1. I have not touched the motor internally: I am running the cobra fi2000r, yes people bag them but its worked fine for me. S&S slip ons and S&E Heavy breather.
Has any one else experinced this, by making the gap wider power increases??
