Carburetor Performance:
Carburetors can become gummed up with age or disuse, affecting idle stability and throttle response. Requires regular cleaning and synchronization.
Cam Chain Tensioner:
Some models may experience wear on the automatic cam chain tensioner, leading to rattling noise. Manual replacement might be recommended for reliability.
Suspension Seals:
Fork seals can degrade over time, leading to oil leaks. Rear shock absorber damping may also decrease with age and mileage.
