Engine features
This power unit, despite the primitive design, has an impressive margin of safety. It is easy to repair and maintain, although today it can be difficult to find consumables for this model. During operation, it can be revealed that the most vulnerable part of the motor is the timing belt drive. On the one hand, it reduces the noise of the internal combustion engine, but on the other hand, it is more prone to breaking, unlike the chain.
