Frequently Asked Questions

How many valve springs are included, and does one kit service a complete CB350F or CB400F cylinder head?

Eight Kibblewhite high-performance springs are included. The four-cylinder CB350F and CB400F engines have eight valve positions, so one eight-spring kit services one complete cylinder head.

Can the original CB350F or CB400F valve-spring retainers be used with Kibblewhite kit 30-1032?

Yes. Kibblewhite describes spring-only kit 30-1032 as designed to work with the OEM retainers. The retainers, spring bases and shims should still be inspected during cylinder-head assembly.

What are the Kibblewhite 30-1032 valve-spring specifications?

Kibblewhite specifies a 0.350-inch valve lift, 1.180-inch installed height, 60-pound seat pressure and 140-pound open pressure at 0.350-inch lift for this intake-and-exhaust spring kit.
