Same bike. It was the black version from about 1979-2016, the blue/white version from 2016-2021, and I just switched it back to the black version again. I think I like the black version better, but it’s a fairly easy switch, just an afternoon project. All I changed this time were the tank, seat, rear fender, side covers, and turn signals…pretty easy work for a really different look, all just bolt-on stuff.
Here's a video and YT channel that I think you'd find interesting. This guy, William Moser, demonstrates with lights and sound how different engines of different cylinder counts and firing orders work. This one is for a Laverda Jota.
