Core Specifications and Safety

Precise factory values are essential for maintaining equipment longevity. The text outlines crucial multi-stage cylinder head bolt torque sequences, specifying a final-stage tightening of 55 Nm (40 ft-lb). Engine specification tables list the exact intake valve clearance at 0.11–0.20 mm, while total crankcase oil capacity is documented at 3.10 liters when including the oil filter cartridge. Because these high-performance motorcycles operate under extreme tolerances, always verify your diagnostic readings and ensure you have the correct tools before beginning work to prevent component damage or personal injury. Consult with a certified technician if you encounter unfamiliar diagnostic codes.
