The E3s seem to start the bike better but then again, there never was a starting issue with stock.

Did you have problems with the OEM plugs? If so what problems?

No I never had issues with stock plugs. I decided to try the E3s. Some called it snake oil other swore by them. I try to keep an open mind about stuff so I tried them. You guys know all about that, Dyno vrs.......................well you know.

I remember the big ad blitz for "Rapid Fire" plugs a few years ago. I tried them in a stout small block chevy, no real difference in power, much shorter life, money thrown down the drain. Back to stock plugs. A friend tried plugs with 4 points, same results. Those were carbed engines, Holly 750 4 barrel spreadbore double pumpers, big fuel dumpers. HEI ignition systems, the works.
Today's fuel injection systems in conjunction with the ignition systems do a pretty good job doing what they do. I'm going to ride it, stock plugs and all.
I have already been down the plug road before.

please be honest, now that you have new stock plugs can you feel or hear the bike running better ? you may have felt an improvement with the E3s but it was probably old vs new plugs

I am being honest when I say the bike started better with E3s and even with brand new stock the E3s were still better. This is definitely a plug malfunction. With an ohm meter probe on one end and the other on the center electrode, the bad plug is all over the place compared to the plug that still works. But YES gentlemen, I will stay with stock sparks. An oh to be totally honest, my 1965 sportster kicker would NOT start cold with the three sets of stock plugs with any less than five to seven kicks. The splitfires plugs everyone laughs at, would fire that that XLH in two kicks cold every time. Some bikes like certain plugs, ask any old timer and they will tell you that.
