'23-'25 CVO’s check valve lift to determine compatibility with KPMI spring kits.
Includes:
• 8x Titanium Retainers
• 8x H.T. Steel Basewashers
• 8x H.T. Keepers (9°)
• 8x CrSi Valve Springs
• 8x Red Viton® Seals
• 8x H.T. Steel Adjustable Shim
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.
- This system must be run with KPMI's newer style M8 valve guides, which are shortened for 0.675" valve lift.
