That looks like a Ness Big Sucker intake. Take the screws off, remove the top plate, TBs are under there.
Clean the air filter at the same time. Looks like a K&N filter, so use their procedure.
I would replace the fuel line while it's apart. Short piece of fuel injection hose from an auto parts store will work and it's cheap. The Vic line is a special shaped hose and a little more expensive, but both are worth it as cheap insurance.
Take your time. Good luck.
Every day is a good day to ride. Some days are just better than others.
