Always start with the simple things and rule them out.
You try running it with the tank filler cap open rules out a partially blocked breather (when tank is less than half full of fuel stops it spilling)
Is the fuel tap turned on fully
Check the fuel pipe to ensure it is fitted correctly and not flattened. The pipe to the tank is routed under the frame cross link, many route it over it and the tank flattens it.
Check the fuel filter and change it if unsure.
Check the Air Filter is it badly clogged, I have seen many a DIY mechanic strip the carbs when all it needed was a new filter.
Since the tank is off
Remove top of one Carb (right side is easist) to see if it has factory restriction (His dudeness pictures show you what you are looking for on the cover)
Drain the carbs could be dirt being sucked up
Check the float heights with a plastic hose attached to the the drain hole.
Check for loose spark plug caps.
If all these check out come back to the forum and we can suggest other options
These are all easy thing to do before you start stripping anything
