Diagnostic Tools:
Requires proprietary Harley-Davidson diagnostic tools (e.g., WHIP, Digital Technician) for advanced electronic troubleshooting and ECU flashing, covered in this manual.
First Service:
1000 miles (1600 km) or 6 months (whichever comes first): Engine oil and filter change, primary chaincase oil change, inspection of all critical components, adjustment of controls, tire pressure check.
Subsequent Service:
Every 5000 miles (8000 km) or 12 months: Engine oil and filter change, primary chaincase oil change, inspection and lubrication of clutch and throttle cables, inspection of brake system, drive belt tension check and lubrication.
Major Service Intervals:
Refer to manual for specific intervals for spark plug replacement (e.g., 15,000-20,000 miles), final drive belt replacement (e.g., 30,000-40,000 miles), brake fluid flush (e.g., every 2 years).
Engine Oil:
Harley-Davidson 20W-50 SYN3 (Synthetic) or an equivalent premium quality motorcycle oil meeting Harley-Davidson specifications.
Primary Chaincase Fluid:
