Andrews Camshaft (ref. 212030) — J cams designed for Harley twins from the Vintage/Classic and Touring universes. Machined in the United States on Landis CNC grinders from alloy steel, these cams have been computer-developed to provide a sharper engine response at mid and high RPM, suitable for light urban use and light drag.

• Lifter compatibility: Works with solid or hydraulic lifters; idle preserved up to 6,000 RPM with original springs.
• Installation: Ready to install, does not require cylinder head machining. It is essential to check coil bind, valve-to-valve clearance, and valve-to-piston clearance before installation.
• Technical specifications:
  • Application: Intake & Exhaust
  • Intake duration: 242°
  • Exhaust duration: 242°
  • Exhaust open: 41°
  • Intake close: 41°
  • Exhaust close: 21°
• Historical note: On engines from late 1977 onwards, the primitive diameter of the shaft, pinion, and breather valve wheel has been modified. These parts are not interchangeable with earlier versions except as a complete kit; post-'77 pinions feature a machined circular groove on the outer face.
• Recommended uses: Ideal for Harley 1340 (Wide Glide, Low Rider, Sport Glide 1984) and other classic twins seeking more engine character without heavy modifications.

Andrews offers a robust cam here for riders looking for a more responsive rev range while remaining compatible with original valve trains — choose it if you want an improvement in the usable range without compromising engine architecture.
