Here's what I would start with: pull the speedometer cable out of its sheath from the bottom, clean it, and grease it. Route it such that there aren't any sharp bends in the cable as these are stress points that increase the likelihood of breaks.

If you can see a bolt or screw, check it to make sure it's tight.

Change the brake fluid in at least the front reservoir/brake line. The stuff that's in it is just terrible. Some are worse than others, but it's good to have reliable fluid in. Spray some brake cleaner on the rotors and make sure there isn't any shipping grease there.

In my opinion, it's a good idea to check the valve lash early on. It shouldn't need to be done right out of the crate, but I was glad to have checked mine before the recommended interval because it was pretty tight.

Be aware that the engine loosens up a lot over the first few hundred miles. Don't be dispirited if it's not performing as expected right off the pallet.

I'm sure there's more, but that's a good start. Enjoy!
