if your bike starts cold without the choke it may be too rich and have a too large pilot jet. If it cuts out wide open pinned after it is all warmed up it may be too rich on the main jet. If gas pours out the overflow when you kick or lean the bike over like on a kickstand then the float level is possibly too high and will cause low end running problems. These are basic non complicated things you can do as a rookie to start.
I know for a fact that I have bad packing in my bikethe first thing I would do is take the carb apart and write down the jets that are in it, the needle number and what clip from the top it is in. Then compare to the stock jetting per the book. Then it would come down to your elevation, float level, clip setting, is the PV opening or sticking, silencer packed, plug good, etc. Always start with whats in it vs what you think is in it. Work from there. Generally tho, your pilot jet or float level is too big/too high as a start since it starts cold no choke.
that's good to knowfresh packing gives you back your midrange
