With a higher than standard compression ratio you probably need to adjust the ignition timing a few degrees (cannot remember which way - advance or retard - probably retard). The extra compression would make it run hotter anyway but if the spark timing is sub optimal that will definitely make it run hotter still. Extra heat > lubrication breakdown > ring and bore wear > excessive pressure in crankcase - maybe?
