As motor oil any commercial multi-grade oil (SAE 20 W 50) may be used.
Instead of oil-grease mixtures for the transmission (Konsul, OSL), a transmission oil SAE 140 should be used.

Ignition malfunction when engine is hot

If bikes with a built-in ignition coil (Max, Lux) have a complete ignition failure, then a new coil must be installed. We have new ignition coils available for many motorcycles.
