Aerox 100 Motor Minarelli 4VP Zerlegung – Abgerissene Schrauben & versteckter Tuning-Zylinder?!

This video shows the complete disassembly of a Minarelli 4VP 100cc 2-stroke engine for detailed condition analysis and damage assessment. The engine is systematically disassembled to inspect typical weak points: Thread condition, mounting points, sealing surfaces, bearings, crankshaft seals, and the entire crankshaft and cylinder assembly. Several technical issues become apparent during disassembly: Broken or stripped screws Partially damaged threads Unclear pre-assembly/traces of previous modifications An unexpected detail is discovered: the engine is already equipped with a performance cylinder – raising further questions about the previous tuning, compression ratio, and durability. Topics covered include: Visual inspection of the crankshaft, connecting rods, and bearings Condition of the cylinder, piston, and bore Assessment of the reusability of individual components Possible causes of damage (assembly errors, thermal stress, incorrect torque values, material fatigue) The goal is to create a solid foundation for future rebuilds – focusing on durability, tight tolerances, and high-performance component selection. For everyone who prefers measuring, testing, and understanding rather than just swapping parts.
