does anyone know if you have to change the spark plug gap on these or something like that? i know on my dads 4 stroke evolution kit he had to gap them back to like 16,000ths or something like that.
BPR9EIX .025 gap been running these plugs on a BD TM1000 up to 17lbs with no problems.....also running same plugs on my 2013 BD M8 up to 10lbs no problems. Both Sleds were set up by Reid Hedlund at Boondocker Canada. I have also ran BPR9EIX right out of the box for a short time without checking gaps and they still worked just fine, cant say I noticed much of a difference.
