    Seems every cross reference has different numbers.
    I have NGK DR8EA in my bikes. Crosses to Champion Z9Y or RA6HC or RA8YC.
    WHich is it??? All of them?

    Also get AC S102F, Autolite 2796. They don't seem to stock NGK's around
    here any more.

    9 sounds about right - I'm pretty sure 6 is way too hot.

    If 9s keep fouling, thrash it harder or change to 8s.

    If you fit 6s, you can't un-thrash it to fix a holed piston.

    Must admit I can't remember the last time I had trouble with NGK and the
    same isn't true of Champion.

    All the makes that were any worse than champion seem to be long gone.
