Technical Documentation

Spanning twenty-two distinct sections, this publication delivers authoritative reference material for the CBX series. It breaks down general inspection protocols, maintenance cycles, and lubrication systems—including the oil cooler. You get an in-depth look at internal engine operations. The documentation highlights top-end service requirements for the DOHC 4-valve cylinder head. It also details fuel system calibration for the VB60A carburetors and electrical component troubleshooting for the transistorized ignition system. Moving to the chassis, the manual provides a thorough breakdown of the hydraulic disc brake systems, swing arm suspension, and steering head bearing adjustments.

Specification Highlights

Accurate reference values are crucial for a machine this complex. The cylinder head specification table sets valve clearance for both intake and exhaust at exactly 0.08 mm (0.003 in). Compression pressure for the vertical six-cylinder engine is documented at 12 kg/cm² (170 psi). Engine oil capacity is rated at 4.0 liters for standard changes, scaling up to 5.5 liters during a complete engine assembly. Working on a vintage Super Sport requires precision and focus. Always double-check torque values against these factory metrics and ensure your workspace is well-ventilated when handling fuel system components to maintain a safe shop environment.
