Re: My first ride... No joy.
It's hard to tell with a cell phone photo but it looks like there's no clamp or bracket on the muffler. I don't think I'd want to run one of these things very much without having the middle or lower end of the muffler clamped to the bike frame. With that much metal cantilevered off those two exhaust studs and such a small mating area to the engine the stress from vibration and the weight of the muffler is very likely to break off a stud.
