Disadvantages, breakdowns and problems of ZMZ 402

The motor is very noisy, prone to twitching and vibration due to its design.

The weak point of the engine is considered to be the ever-flowing rear crankshaft oil seal.

The unit often overheats and the workmanship of the cooling system is to blame

Since there are no hydraulic lifters, you have to adjust the valves every 15 km

The carburetor and ignition system components have a low resource here.
