On most of them, there is a phillips screw in the middle of the knob.
Shine a flashlight on the end of the knob and you should be able to see it. Hold the knob and apply firm pressure as you turn. It has been in there a while and it will be a little hard to turn at first.

And a few Harleys
Let me know how that dash goes Doug. I've been thinking of different ways to replace the foam dash on my 86 too. I've thought about making a mold from the old one and creating a new one by pouring a resin into it then cleaning it up and having it chrome plated. It's too bad lockhart doesn't make a carbon fiber dash for our bikes like they do for newer models. The aluminum idea sounds cool too. Anyways good luck with your project.

found that the trip knob is a friction fit. I am still whittling away on the aluminum dash which I don't think will be a big problem to install but we shall see what troubles I run into. I'am thinking of an engine turned finish for the aluminum as opposed to a high polish due to reflection problems when riding.
