We correct the factory shortcomings by bead blasting the castings, pocket-porting the bowls, and performing a precision performance 4-angle valve job.
We use Black Diamond™ 2.100” intake valves and 1.630” exhaust valves — these valves, combined with our proven pocket porting, correct the throat diameters and drastically improve the factory port velocity, flow, and overall power output.
Paired with corrected valve springs, this eliminates the common CVO issue of premature cam and lifter wear.
• 10.5:1 Forged .010 Pistons
Precision-fit to your heads for crisp throttle response, improved efficiency, and stronger cylinder pressure without sacrificing pump-gas reliability.
• Your Choice of Shop67 Camshaft:
567 Hot Rod Cam — perfect for the average touring rider; big low-end punch, broad torque, and strong everywhere.
640HT Cam — the aggressive option for riders who want sharper mid-range smack and stronger pull through the upper RPM range.
• Matched & Measured Assembly
Every component is cleaned, inspected, measured, and prepped so your top end goes together smoothly and runs right the first time.
Expected Character & Performance
567 Cam Option
Big torque, instant throttle response, and a classic touring hot-rod feel. Ideal for loaded bikes, two-up riding, and everyday street use.
640HT Cam Option
