Harley Softail 1992 with EVO engine

Moin moin, I’m about to buy a Harley Davidson Softail Heritage Classic built in 1992 with 1340cc and 63hp EVO engine. Running it is 20,000km. What can you say about the engine? It was installed quite often from 1984 to 1999. Vulnerable engine or an indestructible device? Guessing or driving from such an old box? What I could find in the net and what I heard from the circle of some Harley drivers is not a bad engine and not a bad model the Sof tail Heritage Classic. What do you say?
