|
Maintenance
|
Service Intervals
|
Oil Change Interval:
|
Highly dependent on usage (e.g., racing hours vs. casual trail riding). Typically every 10-20 hours of hard use for racing, or more frequently for optimal engine life. Manual will provide specific guidelines.
|
Air Filter Cleaning:
|
Frequent cleaning/replacement recommended, especially in dusty conditions (e.g., after every few rides).
|
Valve Clearance Check:
|
Typically checked every 15-30 hours of operation or annually. Manual will provide precise intervals and specifications.
|
