obviously Boksi has knowledge of working on his bike - since he had to fiddle with it himself to figure out what went wrong - thus not sure the reason for having someone else installing the handlebar. i learned early on that very few mechanics (or self-proclaimed mechanics) will treat your bike as if it was their own, consequently if you can do it yourself - do it yourself. These old bikes are pretty simple to work on - no computer plug in needed to diagnose engine, and not a bunch of electronics chips / computers etc that can go wrong, like on newer bikes and cars! happy he figured it out with the group support.
