This comprehensive PDF file contains the complete, original owner’s manual (first edition, July 1990) for the 1991 Yamaha TT600B. For the 1991 model year, Yamaha’s Italian importer, Belgarda, significantly upgraded the venerable TT600 platform, mating the reliable XT600K kick-start engine to high-end YZ-spec Kayaba upside-down forks and an Öhlins rear shock. This detailed guide is absolutely essential for riders to fully understand the bike’s high-performance suspension components, carburetor adjustments, and the strict maintenance routines required for serious off-road riding.
The manual covers the following key topics in detail:
- Motorcycle Overview and Safety: A detailed introduction to the bike’s minimalist, off-road-focused layout. It emphasizes safe riding practices for trail and enduro environments and explains the location of all critical components on the tubular steel frame.
- Controls and Operation: A thorough breakdown of the basic handlebar controls, the manual decompression lever (if equipped), and the specific kick-start procedure necessary to fire up the big 595cc 4-valve single-cylinder engine. It also explains the function of the 5-speed gearbox and the dual-stage Teikei Y27PVX1 carburetor.
- Suspension Setup: Crucial instructions for adjusting the Belgarda-spec suspension to fit the rider’s weight and terrain. It details how to adjust the 43mm Kayaba upside-down front forks and the premium Öhlins rear shock absorber for compression and rebound damping, ensuring maximum traction and control over rough ground.
- Routine Maintenance: Step-by-step scheduled maintenance charts tailored for a machine subjected to mud, dust, and hard use. It includes vital instructions for cleaning and oiling the air filter, checking and changing the engine oil (explaining the dry-sump lubrication system), inspecting and adjusting the drive chain, checking brake pads (for the Brembo front and Nissin rear brakes), and maintaining the spoke wheels and tires.
- Troubleshooting and Specifications: Practical advice for dealing with common running issues on the trail, along with a comprehensive fold-out wiring diagram and specific torque values for critical fasteners.
Whether you need to adjust the rebound damping on your Öhlins shock, check the oil level in the dry-sump system, or trace a wiring fault using the included diagram, this manual is a vital resource for keeping your classic 1991 Yamaha TT600B ready for the dirt.
