Default Honda GX31 vibration problem?

Hi
I read from a lawncare forum that the 4 cycle Honda GX31 31cc engine have vibration problem at top RPM. The vibration were so bad that it actually crack the crankcase!!! Anyone have experience of this problem on the unmodified engine only. I can understand if you modify the engine, you are pushing it to the limit. But for an unmodified engine, it is hard to believe it would do this. Any comments?

Is the GX31 design robust or the GX35 is better?
Thanks

My GX31 runs on the stock mag with a slightly trimmed flywheel. I've noticed no unusual vibrations from idle all the way up to full thottle. I'm pulling 6600 rpms with a 20x6 zinger prop.
