The last one I ran on the Pig went 3k or so before I pulled it due to top end noise and it was the shortest life of any motor I've owned. (small end rod wear killed it)
I admit I seem to have better luck than average, but it's not too hard to realize gouging and wailing on a tiny engine made with barely adequate materials will not promote reliability.
Don't ask it for more than it is capable of and it will last much, much longer.
Abuse any machine and it will eventually fail. Treat them right and they'll return the favor. I've put a lot of miles on my motorized bicycles and have never had a major engine failure.
Want to go fast? Buy a motorcycle.
Want to race? Be prepared for things breaking.
Want to just enjoy the ride? Treat the bike and engine well. Proper use and maintenance will go a long way.
