Frequently Asked Questions
How many Honda 16211-404-000 carb holders are included?
Four carb holders are included, enough for all four carburetors on one 1977-1978 Honda CB550K. They replace Honda OEM 16211-404-000.
How many clamps are needed for the four CB550K carb holders?
A complete four-holder installation uses eight clamps, one at each end of every holder. If the originals cannot be reused, the specified options are eight 45-47mm band clamps, part 15-0688.
What should be checked when replacing engine-to-carburetor holders?
Clean the cylinder-head and carburetor spigots, seat every holder fully and inspect the clamps. Synchronize the carburetors and check for intake leaks after installation because an air leak can create a lean running condition.
