Initial Engine Start and Break-in Period
After assembly and adding fuel, the engine may require several attempts to start as the fuel system primes. Do not continuously crank the engine for extended periods to avoid damage to the starter. If the engine does not start, try holding the throttle open at different positions while cranking briefly.
A critical break-in period of approximately 300 kilometers (186 miles) is required for new engines. During this period, avoid high speeds, rapid acceleration, and prolonged full-throttle operation. Following the break-in procedure outlined in the full owner's manual is essential for engine longevity and optimal performance.
