Not for a Harley, but for both my cars I did. Key point to look for when buying a CD version is (1) Does it have a Search function (some Don't) and (2) Does it have 'Hot Links' to the key words you searched on.
I can tell you from experience, that if it does not have those two features, you will go crazy trying to look something up.
But most of the time, CD versions of manuals are cheap and it won't be a big lose if you hate it.
Hoop!
