you using a molkt carb still?

if so ditch it and upgrade to an oko26mm youll never have an issue again once to set it up, and that will only need the needle played with.

as for the noise, yx's are known for top end rattles and noises, some say its rocker noise some say other things are to blame..

mind rattles like hell once warned up but has never failed me..

might pay to get a video of this noise, try and use a good camera tho or else it will be useless..

by the way the bogging you have is more than likely just needle adjustment..
