Wal-mart sells more oil on a day then many auto parts stores sell in a week.
Champion spark plugs should be illegal no matter what.

Things which will reduce engine life, in order from most to least devastating:
Champion spark plugs
Lack of oil (uncommon)
Turbocharging or supercharging (rare)
Other extreme power modifications (rare)
Roadracing (You should be able to tell if it's been a racebike)
Drag racing (unusual)
Infrequent/rare oil changes (somewhat common)
Long-term storage in a damp environment (somewhat common)
Infrequent/rare valve adjustment (common)
Overly tight drive chain (uncommon)
Infrequent, short riding (less than about 20 minutes) (common)
Other than these things, the Ninja 250 motor is pretty bulletproof.
