Known Issues Overview:
While generally robust, common areas for attention include the regulator/rectifier (prone to overheating), clutch slave cylinder seals, and general wear and tear on high-mileage components. Chain and sprockets require diligent maintenance due to high torque.
Regulator Rectifier Failure:
A common issue across many Japanese motorcycles of this era, the R/R can fail due to heat buildup, leading to battery charging problems. Upgraded aftermarket units are available.
Clutch Slave Cylinder Leaks:
Occasionally, the seals in the hydraulic clutch slave cylinder can degrade, leading to fluid leaks and a spongy clutch lever.
Cam Chain Tensioner:
Some early models may have experienced issues with the automatic cam chain tensioner, potentially leading to rattling noises. Manual CCTs are a common upgrade.
