Description

Upgrade your valvetrain with this High-Performance Kibblewhite Black Diamond Exhaust Valve. Made in the USA by Kibblewhite, who have been making high-quality performance parts for 75+ years.

All Black Diamond stainless steel valves are impregnated by a special German process to a depth of .002, with a surface build-up of .0002. The Black Diamond process improves wear properties, reduces friction, and provides resistance to corrosion and wear that is superior to chrome and nickel electrolysis plating.

Each valve is designed using Finite Element Analysis software, and profiles are tested on a computerized flow bench. Black Diamond Valves are lightweight, strong, one-piece forgings with profiles that provide excellent flow characteristics.

Sold each, order the quantity you require.

Frequently Asked Questions

How many Kibblewhite Black Diamond exhaust valves are included and required?

One Kibblewhite exhaust valve is included. The listed SOHC CB750 engine uses four exhaust valves, so four are required to replace every exhaust valve in one cylinder head.

What is the Kibblewhite Black Diamond treatment?

Kibblewhite uses a surface treatment on its one-piece stainless-steel valve to improve wear, friction and corrosion properties. The valve is made in the USA for the specified 1969-1977 CB750K, 1975-1976 CB750F and 1976-1977 CB750A applications.

Can a performance exhaust valve be installed without checking the cylinder head?

No. Measure stem-to-guide clearance, inspect and machine the valve seat as needed and check spring condition, installed height, retainer clearance and valve-to-piston clearance. Set final valve clearance to the Honda or valvetrain manufacturer's specification.
