Mods are in my sig! I have my spark plugs gapped at .35 and still have a misfire every 10-20 seconds you can hear the exhaust like pfoot. What should I gap them at there NGK one step cooler BKR7E coppers. Thanks ahead guys.

 

.o35 is fine for your set up.

Pull em and read em.

 

.035 might be a bit tight. i run mine at .038 with the same setup. i get the odd misfire on the scan gauge, but no exhaust pop.
