1975 Honda CB550K · Engine Covers Buying guide

Covers that set off the engine

Choose the cover for the actual position being repaired, then compare its reference and fixing points. Genuine Honda alternator and breather covers are listed alongside aftermarket chrome options; finish alone does not identify the right cover or its supplied hardware.

Alternator cover years

The genuine Honda alternator-cover listing names the 1974-76 CB550K, including this year. An alternator-cover gasket is separately listed. Inspect the existing joint and fixing hardware, and check what the cover purchase supplies before completing the order for the repair.

Finned rocker caps

The chrome finned rocker caps are an aftermarket style rather than the plain originals. Each one ships singly and comes with its own fresh gasket. Owners keeping a stock look may prefer to reuse the originals with new O-rings.

Engine cover FAQs

Does the points cover come with screws?

No. The listing says fixing hardware is a separate purchase. The cover replaces Honda 30370-300-020, a common casualty of dents and rust, and lists 1974-78 CB550K bikes.

Does the breather cover include its gasket?

The genuine Honda breather-cover listing says its gasket is not included. The cover is sold individually and specifies one per motorcycle. Inspect the existing gasket and arrange the appropriate separate replacement if needed before starting the cover repair.

Should I replace the point plate gasket?

Inspect the existing gasket and the cover joint when planning points-cover work. The replacement gasket listing references Honda 30372-300-300 and names the 1974-78 CB550K. Use the appropriate service instructions to decide whether the removed gasket can be reused or needs replacement.
