Initial Service:
First service typically at 1,000 miles (1600 km).
Regular Oil Change:
Every 5,000 miles (8,000 km) or annually, whichever comes first. Check manual for specific oil type and capacity.
Transmission Oil Change:
Every 10,000 miles (16,000 km) or annually.
Primary Chain Tensioner:
Inspect at 1,000 miles, then every 10,000 miles. Replace if wear is detected (automatic tensioner type).

Fork Oil Type:
Refer to manual for specific fork oil weight and quantity for Springer fork.
Cam Chain Tensioners:
Early Twin Cam models (pre-2007) are known for wear on the hydraulic cam chain tensioners, which can lead to noise and potential failure. Upgraded hydraulic tensioners or conversion to a gear-driven cam system is a common upgrade.
Oil Leaks:
Common on older Harleys, particularly around primary cover, rocker boxes, and pushrod tubes. Manual provides seals and gasket replacement procedures.
Electrical Connectors:
Corrosion or loose connections can cause intermittent electrical faults. Manual helps in tracing and fixing these.
Heritage:
Harley-Davidson, established 1903, synonymous with American motorcycle culture and V-twin engines.
Softail Lineage:
The Softail platform, introduced in 1983, mimicked the rigid appearance of early hardtail frames while incorporating hidden rear suspension for comfort. The Springer front fork is a nod to pre-WWII Harley-Davidson styling.
Flstsci Specifics:
The FLSTSCI variant specifically designates the Softail Springer Classic model, featuring the iconic springer fork, which adds significant character and a unique riding feel.
Production Period:
The Twin Cam 88B engine was in production through the mid-2000s, with the Softail Springer Classic being a prominent model within that era.
