Hello, I'm looking for information on which spark plugs to use. I have what Mr Honda say's is probably a 1967 Dream survivor in mint condition. Any information would be helpful and appreciated.

1965 CA77 Owner's Manual calls for NGK D6HW spark plugs. Today, the closest match would be NGK D6HA.
NGK D8HA (colder) plugs are spec'd for CL and CB 305s. Would likely be OK for CA77 too.

What a nice looking Dream, Royster!
Please add it to the Dream Registry www.honda305.com/dream/registry
On spark plugs, I would only add that if you find yourself testing various crossover numbers, be sure that the plug itself is the 'non resistor' type. On these early bikes (and not only on Honda) the cap offers the resistance and a resistor plug in series would degrade the spark.

Hi,
I picked up a '66 CA78 in Sept. While I haven't started it yet (waiting on carb parts) it came with a new aftermarket ign coil. I plan on using non-resistor plug caps and NGK DR8HS plugs. Since resistor caps are getting harder to track down I've begun switching over to non-resistor caps & resistor plugs on all my old junk (cb350, '72 MG Eldo & '87 MG Lemans). On my newer stuff I've never had a resister plug fail but I have had resister cap failures on my older bikes, fwiw.
