Kawasaki Vulcan 1500 Classic (Carburettor, pre-2005) Maintenance Schedule and Service Intervals

This is the maintenance schedule with associated service intervals for the Kawasaki Vulcan 1500 Classic that was carburettor fed.

Before the Kawasaki Vulcan 1500 FI range, the Kawasaki Vulcan 1500 Classic was fed by a single carburettor.

For a few years, the Vulcan 1500 was sold alongside the 1500 FI. They had the same capacity engine, but changes went beyond fuelling… the motorcycles had different frames and significant other body parts. It’s quite confusing and, in retrospect, entirely unnecessary. C’mon, Kawasaki!

General information about the Kawasaki Vulcan 1500 Classic

The Vulcan 1500 Classic has a 1,470 cc liquid-cooled SOHC 50-degree V-twin engine with a single-pin crankshaft paired with a 5-Speed transmission. It has a 27.6-inch (700 mm) seat height, wide handlebar, forward-mounted floorboards.

With a big V-twin engine displacing 90 cubic inches, the Kawasaki Vulcan 1500 Classic gets attention for its looks, technical features, and power.

Each cylinder has sculpted and polished cooling fins that contrast with the black cast engine. The result really catches the eye. The fins are functional in that they cool the engine, but there’s also a radiator hidden between the frame downtubes.

The Vulcan 1500 Classic also has a large airbox crossover tube between the cylinders. This tube increases airflow to the carburettor, a single 40mm Keihin model. A throttle position sensor is connected to the electronic ignition to vary ignition timing according to throttle setting and engine rpm. The result is better engine response and lower fuel consumption.

Each of these big V-twin’s cylinders has four valves actuated by a single overhead cam. Two valve springs are used on all valves to ensure tight valve closure, while hydraulic valve lash adjusters automatically maintain valve clearance for smooth engine performance, reduced noise, and no maintenance. Automatic cam chain tensioners keep cam timing accurate and provide greater reliability with minimal upkeep.
