I too, am a convert from the Harley world (and couldn´t be happier)I traded a 71 Sporty even up for my 84 Aspencade. The vibration you´re getting is in the driveshaft...mine does it too. Don´t know why but it´s been like that since I got it. I´m replacing my am/fm cassete with a cd/mp3 set-up...keep an eye on the starter...other than that, you just put gas in the damned thing and ride, tools not neccessary !
