• A 226-page definitive factory reference providing standard service limits and adjustment procedures for all key subsystems

Manual Organization

This workshop reference provides direct technical support for the entire motorcycle. Initial chapters establish foundational shop safety protocols, model identification, and standard fastener torque values. Working on high-performance two-stroke machinery requires proper lifting equipment and a well-ventilated workspace to safely handle critical fluids.

Past the fundamentals, the manual breaks the machine down by functional area. It details the frame, bodywork, exhaust, and the complete engine assembly. This includes specific teardown information for the top-end, transmission, and clutch. You will also find specialized sections covering H.P.P. valve maintenance, cooling system overhauls, and electrical diagnostics. Each system chapter includes precise service limits for wear components. Maintenance schedules are tied directly to racing hours or event counts, keeping the bike dialed to strict factory tolerances.

Technical Specification Preview

Having direct access to factory hard data saves time at the workbench. The text documents a cylinder head warpage service limit of 0.05 mm and piston-to-cylinder clearances ranging from 0.035 to 0.050 mm. It clearly outlines exact fluid capacities. A standard drain requires 0.57 liters of transmission oil, while a complete rebuild takes 0.65 liters.

You also get clear replacement thresholds, such as the 0.15 mm clutch plate warpage limit. Essential ignition system benchmarks, like the 0.5–0.6 mm spark plug gap and specific coil resistance ranges, are mapped out to ensure reliable electrical operation.
