Question about 1983 Yamaha XS 400 L Maxim
It is highly likely you have a sticking/dirty needle and seat in(one or both) fo the carburettor/s.
I quick trick is to loosen the carby drain screws( located at the bottom of each carby) and as the fuel drains out, tap the bowls with the handle of a screwdriver. This is often enough to loosen the blockage and your leak will stop.
Otherwise, if the leak continues, you will need to remove the carbys, and clean them taking particular attention to the needles and seats and replace if necessary.
Afterwords I strongly recommend you fit an in-line fuel filter (if you have room) for some added protection from the problem re-occurring
