Known Issues Carburetor Clogging: Common in 2-stroke engines due to fuel quality, oil residue, or infrequent use, leading to poor running or no start. Exhaust Decarbonization: Carbon buildup in the exhaust port and muffler is typical for 2-stroke engines and can reduce performance; requires periodic cleaning. Oil Injection Pump Failure: Can lead to engine seizure if not detected and repaired promptly. Requires checking the pump's operation and oil delivery. Cvt Belt Wear: Wear on the drive belt can cause slippage, poor acceleration, and eventual failure. Regular inspection is crucial. 📚 Vehicle History Brand Heritage Manufacturer: Aprilia S.p.A., Italy Model Evolution Platform Introduction: The Scarabeo line, known for its retro-modern styling and practicality, was first introduced in the mid-1990s.
