Frequently Asked Questions
How much exhaust hardware is included?
The set contains eight studs, eight washers and eight flange nuts, or 24 components in total. It provides two exhaust studs for each port on one compatible four-cylinder Honda engine.
Which motorcycles use the exhaust-stud set?
It is sized for the listed 1971-1978 Honda CB550F, CB550K and CB500K cylinder head and exhaust-flange arrangement. Confirm any non-stock exhaust uses the same stud spacing and flange thickness.
How should seized or broken exhaust studs be handled?
Soak corroded threads and use controlled heat or proper extraction methods rather than forcing a stud in the aluminum head. Clean and inspect the head threads, install the new studs to the specified depth and tighten the flange nuts evenly with new exhaust gaskets.
