one big thing that saves motors is not over reving !! as well as proper tune.
if your engine is stalling or acting funny dont go and try to restart and get it on the track as soon as possable. (unless the engine ran out of fuel)
check on whats wrong and get the engine retuned and running properly. The engine stalls for a reasion, fix it and you and your engine will be happy..
you can hear and feel when engine bearings are going out..
your motor will have a hissing sound and will not idal properly, will leak fuel, will feel lean, and it will run hotter.
all engines have a life cycle, however when a engine's life is over usually you can replace the conrod, bearings, and give the pistion and sleeve pinched and your engine is good as new...
hope this helps
+1 to everything.
Running too rich(too cold) puts alot of stress on parts. Engines are designed with very tight tolerences. The parts in engines are designed to reach the correct tolerences for running when they reach a certain temp. If you run an engine too cold you put stress on every part of the engine.
As for bearings going, you will hear them rattling when they are done. You can also feel them if you slowly turn the crankshaft by hand. If your engine starts popping plugs often, and your tune is good, check the bearings and rod. A worn out rod bushing or rear bearing will kill plugs.
