and the front one on the cylinder has some kind of wiring or sensor or something coming from it.



that would be the vacume line up to the air injection ( ai ).
most have this removed as it is the cause of the pipe blueing
on stock bikes.

as for the fuel leak at the maifold , I would say that is you vacume leak right there.

get those clamps replaced , make sure the boots are seated
correctly and snug everything .
then see how she runs.
