Description
Description
This Kibblewhite replacement valve shim spring kit is designed for the specific Harley-Davidson applications listed below. Designed for maximum performance.
Key Features
- Designed for maximum performance.
- Features interference-wound, double-chrome silicone springs; heat-treated steel base washers.
- All spring kits should be used together.
- Available in a complete set for one engine.
- Made in the USA.
- Modification necessary to maximize shim contact, KPMI recommends "tipping" (shortening the valve tip).
- There is anticipated to be a rough 0.100" increase in effective stem protrusion with the use of the shim.
