Carburetor Synchronization:

Carburetors can drift out of sync over time, leading to rough idling or uneven power delivery. Regular synchronization is key.

Starter Clutch Noise:

Some owners report a chirping or clicking noise from the starter clutch on startup; this is often considered normal for the design but can sometimes indicate wear.

Rear Brake Pad Wear:

Due to the weight of the bike and typical cruiser riding style, rear brake pads may wear faster than expected.

Vibration:

As a large V-twin, it produces noticeable vibration, which is characteristic of the riding experience but can be exacerbated by incorrect maintenance.
