Known Issues
|
Carburetor Synchronization:
|
Carburetors can drift out of sync, leading to rough idling or poor throttle response. Requires regular synchronization.
|
Cam Chain Tensioner:
|
Some models may experience wear in the automatic cam chain tensioner, leading to a rattling noise. Manual tensioners are a common upgrade.
|
Wiring Harness Connectors:
|
Corrosion or loose connections in electrical connectors can lead to intermittent electrical faults.
|
Stator Output:
|
Occasional failures of the charging system stator can result in insufficient battery charging.
|
Fork Seals:
|
Like many motorcycles of this era, fork seals can degrade over time, leading to oil leaks.
