Have you brought up this issue with the dealer you bought it from? These motors come with a warranty for a reason... I'd have the dealer take a look at it.

If the rattle is common to this particular model, it may be something as simple as installing an o-ring or a rubber washer to correct it. Who knows, maybe Honda already has a tech bulletin regarding this rattle. While it may not necessarily be an issue that could lead to a failure, it sounds like it certainly would be annoying, particularly on a relatively new motor.

My Twatsoo 4 stroke 20hp made a horrible rattling noise at 2000rpm.
Turned out to be the F N R gear lever selector / linkage.
A few wraps of duct tape and l was good!
