Welcome to the VTXOA!
How long has it been parked since previous owner rode it?
Ethanol gas causes clogged jets and clogged emulsion tube holes.
Check/replace vacuum hoses. Hoses crack/split on the ID, vacuum leak can reduce fuel flow.
Test fuel flow, remove hose to carb, have a catch can ready, apply vacuum to petcock vacuum port.
You should have a good fuel stream.
Some of your comments sound like the slide valve diaphragm could have tears in it.
Black smoke at idle, clogged orifices and possibly high float level.
Both exhaust ports getting hot shortly after being started??
