Unless it's a vrod, I remember there not being a valve adjustment. They have hydraulic self adjusting lifters.
If you don't have the 1000 mile service done, you may void the warranty.
My last new HD service was $220 for the initial service. I didn't have it done by an official dealer, but it was documented and done by a licensed mechanic. That's all it took, and my warranty was still valid.
