Set of 4 reproduction drain plug screws, with o-rings, for Keihin carburetors on the ''77 and later Honda CB550, CB750 and many others. If you''ve got a leaky drain plug screw and the threads on the float bowl are intact, you might just need a new o-ring. But wouldn''t it look nice to have all new shinny drain plugs! Sometimes it''s tough to track down the right size o-ring, so here''s a complete plug screw ready to install! People have a tendency to mangle the heads on those drain plug screws due to over tightening them trying to stop the leak, this forces the next person to wrench on it to get it off, don''t be that guy!

Make sure to check the fitment list below. The carbs on some bikes like the CB750 / CB550K changed in 1977, so make sure you have stock carburetors! We also have the drain plugs for models from the early/mid 70''s.
For instance: CB550K carb model X46A and PD46C used this drain screw. CB750K/F carb model 41A, PD42B, PD41B, PD42A used this drain screw.
