Known Issues
|
Carburetor Sync Drift:
|
Carburetors can lose sync over time, leading to rough idling and poor throttle response. Regular syncing is crucial.
|
Electrical Connector Corrosion:
|
Aging electrical connectors can corrode, causing intermittent issues with lighting or ignition.
|
Camchain Tensioner Wear:
|
The automatic cam chain tensioner can wear, leading to a rattling noise from the engine, especially on startup.
|
Clutch Slippage:
|
With high mileage, clutch plates can wear, resulting in slippage under acceleration.
