I have a '94 Wing. When the engine is running, I smell gas, sometimes strongly. I have checked the diaphragm and checked for a noticeable fuel leak with no results. It runs great and starts easily once she is warmed up.
I have seen some leaks around the input and output fittings on the fuel filter. however that was usualy just after a filter change. It is caused by a little ridge on the filter connectors. Can be fixed by sanding them off. Might give the filter a look.

i do not know much about a 94 wing--if it was one of my bikes i would be checking the oil , perhaps pulling the plugs I would want to be sure it wasn't flooding into the oil or down the exhaust pipes
