Transmission Oil Type:
API GL-4 75W/90 or 10W/40 motorcycle gear oil (specific viscosity crucial).
2 Stroke Wear:
Wear on piston, rings, and cylinder bore common with high mileage or poor maintenance due to 2-stroke nature.
Carburetor Issues:
Clogging due to fuel quality, aging rubber parts (diaphragms, O-rings).
Power Valve Sticking:
Carbon buildup can cause the exhaust power valve to stick, affecting performance.
Electrical Gremlins:
Aging wiring harnesses, corroded connectors can lead to intermittent electrical faults.
Suspension Seals:
Front fork seals can weep with age and mileage.
