When I started the bike for the first time since 33 years I came into the carb jetting, ignition setting and plug fouling business. Worse than ever when my old VM29's work different in the new setup with CB750 OEM carb boots.
Now demanding the jets that it should use, before a "little" bit too large.
I fouled some plugs direct, new NGK Iridiums and used D8EA from 1988. Ignition is now OK and jetting almost OK.
I read posts here about plugs and a new factor for my bike, the bad gasoline of today. I hope that Shell V-Power gas will be OK
I have now new NGK D8EA, ordered 8 plugs more of same kind + 8 Denso X24ES-U + 16 good old NGK DR8ES-L. Have I missed any old fav plug?

I remember that I fouled Nippon Denso after a few minutes recommended by my local tuner 28 years ago, installed NGK that worked direct and all days after that. It might have been D8ES or D8ES-L or DR8ES-L
Let's see which plug works best when my jetting is complete?
I might need to buy more CB750's (69-76) for my plugs.
