You should't worry about what other people will think/say about building a cafe out of perfectly good roadworthy bike, its YOUR bike not there's.
I for one cant wait to see your outcome, love a good cafe boxer. So whats your plans, full strip down, new paint etc...
Keep us posted & with plenty of pics [smiley=thumbsup.gif]
