Engine Overview and Common Failures

The weight of the B4A engine according to the catalog is 50 kg. The engine number B4A is located on the cylinder block. It is mostly praised on Indian forums, with no weak points found. The main thing is to monitor the cooling system, as all aluminum engines are afraid of overheating. Since there are no hydraulic lifters, the valves will need to be adjusted every 100,000 km. However, the main problem is the lack of spare parts, only consumables are available.
