My neighbor freaked out on me after I rode my bike down my street once. Just had done some tuning and put a cool head on, wanted to make sure all was well and nothing was leaking. It was in the middle of the day on a sunday and I wasn't even going very fast. Instead of him calling the cops on me, My neighbor came over to my garage and was about ready to fist fight me over it (crazy people).......I wasn't about to let my neighbor get the best of me, and get me arrested for beating the shit outta him.
Like LS3 said, maybe take it somewhere with less houses around when jetting or tuning it?
The lesson I learned was most people don't like the noise and its not worth the drama with neighbors. Just my 02 though.
