    My personal opinion, Yamaha tunes all their motors to run with NGK plugs.

    I'll stick with what they built.

    Agreed. In your case that would be the BP7ES.

    Which you may or may not be able to get in Canada anymore - certainly can't get them where I live (Southern Ontario). I have to order them online now.
