Might sound odd as I've done the query and can read the chart. I've got Bing 63/32/ 323&324 's on my bike. I realize that they aren't listed here either. I'm guessing that they might be the California spec carbs? (yeah, The smog stuff has been stripped off my bike too) Background for the question: Fresh coils, wires, plugs, carbs have been rebuilt, both the bodies and slides are worn and scored pretty good though. Recently the bike ran perfect then has been crappy, poor, intermittent etc. And I'm thinking that the carbs could be the issue, I've done the in place carb cleaner with the jets out, screws out, but haven't pulled them off the bike for the harder inspection. The A&S application chart. Again, I can read and understand it. The real questions are: If I'm shopping for some used parts will the rest on the list work? Do I need a matched pair listed for them to work properly? 01 CARBURETTOR LEFT 64/32/351 1 10/1984 01 CARBURETTOR RIGHT 64/32/352 1 10/1984 01 CARBURETTOR LEFT 64/32/321 1 03/1985 01 CARBURETTOR RIGHT 64/32/332 1 03/1985 01 CARBURETTOR LEFT 64/32/357 1 11/1984 01 CARBURETTOR RIGHT 64/32/358 1 11/1984 01 CARBURETTOR LEFT 64/32/351 1 03/1985 01 CARBURETTOR RIGHT 64/32/352 1 03/1985 Chart is misaligned, Vbulletin condenses your spacing. Alternately if there's a Airhead guru in San Diego willing to take a look, listen... There's Belgian Beer in the Fridge.
