sparkplugs?

fyi .... those plugs are fine ... please don't trash 'em. A wire wheel or wire brush (gently) and some solvent (acetone, lacquer thinner, nail polish remover, kerosene, etc) will clean 'em up. The carbon is a surface buildup easily removed.

Once the electrode is cleaned off, air or blow dry, recheck the gap, and you're good to go.

Phew :)

I wouldn't recommend a hotter plug -- I actually looked into that too when my engine was being 'finessed', and I even called NGK about it. Two things: 1) NGK only offers D6's in the U.S (D7's are available in the UK); 2) Did you know that with each change in the heat range (say from a D8 to a D7), you raise temperature by 200 degrees? I chose not to do that, as it sounded too risky, and instead lowered the float level on that particular carb. My plugs are now perfect, so assuming your jetting specs throughout the entire throttle range are correct, I'd look at float level too.

no way i would throw those out. i keep allmost everything even if i dont think its able to be fixxed..
my battery is new put it to a charger for like 12 hours its strong. but this is my frist time restoring a motorcycle. will 220 fine grit sand paper and nailpolish work? mabey even 2000 grit. i opened up the bowl of the left carbs and it has quite abit of fuel in there even tho the fuel is turned off. im sure its a float problem now.

Only if you want pretty plugs ;)

I use a fine emery board (on the plugs not my nails), but 220 is fine (pun).

Glad you found the issue.

Welcome to late CB77 seat-hell. Read previous posts.

Any good paint stripper will remove the clear coat, just be sure to wear gloves and ventilate ... the stuff is nasty (Methylene Chloride), a known carcinogen, and absorbs through the skin. Then the exposed Aluminum will start to oxidize immediately, so throw some car wax or something after you polish, or rattle-can clear-coat is you want. I used steel wool and lacquer thinner to remove the old yellow coating, but I probably shouldn't have. Steel (even #0000 steel wool) gouges the soft Aluminum and leaves swirl marks (which can be buffed out), but I'm not going for the show look.

Lots of threads here on that stuff.
