I had carbs rebuilt and the mechanic said that i should change my spark plugs to a gapless plug(surface gap) . It has a b9hs-10 ngk and he gave me a buhw ngk and everything is the same except this one is a surface gap. He also said that it would give motor a faster wholeshot than a gapped plug . And i just don't know and want different opinion before i put these plugs in and burn hole in pistons.
So if you have knowledge in yamaha please give me your advise.
