The starter issues are limited to the XV750's. The factory always had crappy starters fitted to the things, but the first two years, '82 & '83, are the worst. To my knowledge the 1100's suffered no such problems. Starters on the XV's are not too bad to access. To fully address the issue, the left sidecover has to come off, but who cares?
They are slow. They are heavy. They also are extremely cramped. If you're a small guy, you could be comfy, but I am truly amazed at how tiny such a 'big' bike can be. The bikes sound strange to me - it's a Veetwin, obviously, but they sound like shit to my ears when they've been uncorked.
The lack of downtubes gives me the willies when I think about frame modfication.
