Technical Data Preview

Knowing the exact numbers saves time and prevents costly mistakes during reassembly. Maintenance tables list the engine oil capacity strictly at 1.40 L. The NGK CR8E spark plug gap requires setting between 0.7 and 0.8 mm. Intake valve clearance ranges from 0.10 to 0.15 mm. For torque specs, the primary drive gear tightening value is 75 Nm. Always use DOT #4 brake fluid for the master cylinders.

Working on high-performance motocross equipment carries inherent mechanical risks. Always ensure you have the proper tools and a solid understanding of the procedures, or consult a certified technician before performing critical services on the engine or chassis.
