Honda GL1500C Valkyrie Maintenance Schedule and Service Intervals

This is the maintenance schedule and associated service intervals for the Honda GL1500C Valkyrie. It’s also known as the Honda Valkyrie, or Honda Valkyrie 1500, to distinguish it from the later 1800 cc Valkyrie.

Honda also released a version of the Honda Valkyrie called the Interstate or Deluxe. These were the same basic motorcycle, but with gear for long-range touring like saddlebags/luggage and a windshield. See pics of them below.

The heart of the Honda GL1500C Valkyrie is a 1520cc liquid-cooled carburettor-fed flat six engine, the same engine from the Honda Gold Wing of the time. The difference is of course the style — the GL1500C Valkyrie is a “cruiser” bike, or a “custom”. It’s nice to look at, exposing the beautiful engine (covered in chrome), and doesn’t attract comments like “why didn’t you just get a car” from people who’ve never ridden a Gold Wing.

Plus, that flat six sound. Like a Porsche 911 when it’s on throttle (with the right exhaust).

About the Honda GL1500C Valkyrie

The Honda GL1500C Valkyrie’s liquid-cooled 1520cc six-cylinder is tuned for excellent roll-on power and sophisticated cruising comfort.

The previous generation Gold Wing-derived engine has six carburetors, aggressive camshaft timing, and a free-flow exhaust system — this is no sedate cruiser, but a power cruiser that can really rev.

The tuned six-into-six exhaust system has three individual outlet pipes enclosed in a single muffler-like casing on each side.

The custom styling appeal includes carefully designed chrome engine accents, including manifolds, timing belt cover and reshaped head covers. The Valkyrie GL1500C has a five-speed transmission with close gear-ratios for exciting roll-on performance.

The Honda GL1500C Valkyrie also has:

• A quiet and virtually maintenance-free shaft drive.
• Simple-to-service screw-and-locknut valve-clearance adjusters.
• A strong, rugged chassis with a solidly mounted engine for confidence-inspiring handling.
• A massive 45mm inverted front fork with 130mm of plush, well-controlled travel, and large-section aluminum alloy top and bottom triple-clamps add to fork rigidity.

The Valkyrie may be a stripped-back Gold Wing, but it has a few creature comforts to help with long-range touring. For example, it has a powerful front halogen headlight with a multi reflector-type lens.

The dash of the Valkyrie is more basic though — a chrome-case-enclosed tachometer and speedometer with white-colored faces.
