WOT throttle sounded ok, the rest was crap, due to jetting issues that guy obviously has no clue how to do either. He was being easy on it also, you ride mine wot your wheels are in the air! Maybe we should email him a link to this page!
It was breaking up some but I didn't hear any unusual knocking noises or see any beat together parts fly out of it while he was riding. Again, not attributing that to his incredible installation methods only point out that even though he whacked it together with a hammer it DOES run.
