Hard Specifications & Data

What exactly is inside? The technical reference sections provide the hard numbers required for precision work. Engine specs include a documented cylinder compression pressure of 1,000 kPa (145 psi) and piston-to-cylinder clearances of 0.025–0.045 mm. Fuel and tuning data highlight a float height of 15.5–16.5 mm alongside an idle speed calibrated to 1,400–1,600 r/min.

You will also find exact fastening requirements, such as 22 Nm for cylinder head nuts and 10 Nm for the head bolts. Secondary reduction ratios (2.500), spark plug gaps (0.6–0.7 mm), and fluid capacities (like the 4.2-liter fuel tank) are all thoroughly documented to factory standards.
