I doubt that engine will wear out now in your ownership. So far, in all my time with cars and bikes, i have never needed a rebore. Maybe its because when buying old ones, they are good at the beginning of my ownership.
Best long term ownership was a Ford Escort oil changed at 2500 miles from new. At 100,000 miles, that engine showed virtually no wear but did need new valve caps due to rubber deteriorating and they fell away. Cars i have now are only with me 21,000 miles so nothing at all to do.
Not working dropped my miles down a lot so even when i was doing over 30,000 miles in a car, not even tyres were needed.
