Maintenance of CF Moto Engines
Proper maintenance is essential for maximizing the performance, reliability, and longevity of your CF Moto engine. Following these maintenance guidelines will help ensure your engine operates at peak efficiency throughout its service life.
Oil & Filter
Recommendation: Change oil and filter every 1,000 miles or annually
Engine oil is the lifeblood of your CF Moto engine, providing crucial lubrication and protection against wear. CF Moto recommends using 10W-40 full synthetic oil for optimal performance and protection across varying temperatures and operating conditions.
Pro tip: Always check oil level when the engine is cold for accurate readings
Air Filter
Recommendation: Inspect every 1,000 km, replace every 3,000 km
The air filter prevents harmful debris from entering your engine. A clean air filter ensures proper air-fuel mixture and optimal combustion. In dusty conditions, check and clean the filter more frequently.
Pro tip: Keep a spare air filter on hand for quick replacement during rides
Cooling System
Recommendation: Change coolant every 2 years or 20,000 km
The cooling system prevents engine overheating by maintaining optimal operating temperatures. Regularly check coolant levels and inspect hoses for leaks or deterioration. Use only manufacturer-recommended coolant for best results.
Pro tip: Bleed the cooling system properly after refilling to prevent air pockets
Valve Clearance
Recommendation: Check every 5,000 km or annually
Proper valve clearance ensures optimal engine performance, fuel efficiency, and component longevity. This adjustment requires specific tools and technical knowledge - consider professional service if you're not experienced.
Pro tip: Listen for ticking noises which may indicate valve clearance issues
