Who makes or sells the best, most complete carb kit for my 7a carbs?
They are the same as for the 657A/B carbs, or any of the 750K1-K5 bikes. The needles are different in the 7A (usually #27301 instead of #27201), but the rest of the carb parts are the same as the earlier ones. There should be no need for anything but gaskets and O-rings in a "rebuild" of those carbs, along with a careful, thorough cleaning.
