MAINTENANCE
To maintain your new engine warranty and to assure proper emissions system operation, regular inspections and servicing must be performed.
Periodic
The motorcycle should be checked frequently (for example, with each tank of gasoline) for fuel or oil leaks and oil level. After the engine is warm, the
idle speed may occasionally require minor adjustment. The air cleaner should be inspected every few hundred miles. See the motorcycle owner’s
manual for other recommended periodic maintenance.
During Break-In
At 50 Miles (80 Kilometers):
1- Change engine oil and filter.
2- Inspect for fuel and oil leaks.
3- Inspect air cleaner element and service as required.
4- Check tightness of exterior fasteners, except head bolts.
Engine Maintenance at 500 Miles (800 Kilometers):
1- Change engine oil and filter.
2- Inspect for fuel and oil leaks.
3- Inspect air cleaner element and service as required.
4- Check tightness of exterior fasteners, except head bolts.
5- Check operation of enrichment device and throttle controls.
6- Check engine idle speed.
7- Check tightness of engine mounts.
Regular Service Intervals
Regular lubrication and maintenance will help keep your new S&S engine operating at peak performance. The following table presents the required
service schedule for normal operating conditions. Failure to complete the required engine maintenance can result in engine damage and an increase
in emissions. Please refer to the motorcycle owner’s manual for any additional required chassis maintenance.

1- S&S recommends that petroleum-based oil not specifically formulated for motorcycles should be changed every 1,000 miles (1,600 kilometers)
after the break-in period.
2- Replace more frequently if required or if engine is operated in a dusty environment.
Motorcycles operated under adverse conditions (severe cold, heat, dusty or wet conditions, extended idling, pro-longed high speed, or
extreme load) should have regular maintenance performed more frequently to ensure safe, reliable operation.
