If you think owning a GG is a hard question, you shoud have tried owning a 01 Husaberg.
Most of the things you listed are just add ons. They are not needed for reliabilty just for different taste in performance. As for the jetting I would also sell my bikes running a little rich if I was the manufacturer. I would rather have my customers rejet for where they live than have them die from running lean.
The kickstands though are a euro standard which sucks. Just ask any Ducati owner who's bike has fallen over.
