Frequently Asked Questions
How many Honda CB valve-stem seals are included, and is one set enough for an engine?
Eight Kibblewhite Viton valve-stem seals are included. Each compatible CB350F, CB400F, CB500K, CB550 or CB650 four-cylinder engine has eight valves, so one set services all eight valve guides.
What Honda OEM valve-stem seal does Kibblewhite set 12-0083 replace?
The eight-piece Kibblewhite set replaces Honda OEM 12209-333-005. These are 100% Viton seals made in the USA for resistance to engine heat, oil, fuel and combustion by-products.
What problem do valve-stem seals help prevent?
Valve-stem seals control oil passing between each valve stem and guide. Hardened or worn seals can allow oil into the combustion chamber, contributing to oil burning, carbon buildup and loss of performance.
