I think it is mostly the same engine (79-83), and regarding the side covers i found a pair close by my hometown (after searching for almost 2 decades) someone stole my originals covers long time ago,i will find a new picture with the panels on.
I love bike porn... Sorry, couldn't resist! They look like they are maybe three years old, not 31!!! Sharp. Very sharp. I hope they get miles -- remember, they were built to produce smiles. They are from my favorite bike period, with the classic, teardrop tank designs. That was the golden age, for me. I may have to print those off, and hang them in my garage... Thanks for sharing! Cheers!
