Engine Overview and Common Failures

The weight of the KL-G4 engine is 175 kg (including attachments). The engine number of the KL-G4 is located at the junction of the block and the cylinder head. This engine is quite reliable, but the aluminum block and cylinder head are very sensitive to overheating. It is not advisable to delay the replacement of spark plugs, otherwise you will have to replace three expensive coils. After 100,000 km, you may encounter oil leaks from under the valve covers. The timing belt lasts for 80,000 km, and its replacement is complex and expensive, but it does not bend if a valve breaks. Since there are no hydraulic lifters here, the valves need to be adjusted every 100,000 km.
