Technical Data Preview

To give you an idea of the technical depth, the manual includes factory-verified tables for fluid capacities, mechanical clearances, and torque specs. For example, cylinder compression is rated at 1,226–1,442 kPa (12.5–14.5 kg/cm²) without the decompressor activated. Engine oil capacity requires 2.0 liters for a standard drain, bumping up to 2.1 liters if you change the filter. The front and rear final reduction gears specify Hypoid gear oil SAE #80, and valve clearance for both intake and exhaust is set at 0.15 mm (0.006 in).
