my friend wants to now if the wrist pin needs changed every 30hrs of ride time?

NO... It should last quite a bit longer than that...

The earlier models had issues with oiling, this may have been one of the solutions was to require frequent replacements of such parts.

If your friend has an 07 or newer, they need not worry.

If your friend has an 04, 05 or 06 they may want to look into the oil mod or oil upgrade. There is some debate over the severity and necessity of the mod, especially among recreational riders.

Here are some links to get you started:
