I never thought it was difficult. If possible run most of the gas out of the tank, makes it lighter and easier to handle but not strictly necessary. There are only 2 bolts. One is right behind the steering head and easily reached with a socket on a short extension. 8 mm IIRC. Just loosen that one several turns, don't completely remove it. You have to take the seat off to get to the back bolt. Take it out, then you can lift the back of the tank up slightly. There are two vent hoses near the back that push on to vertical nipples. Just pull them off. You may want to label them as it's very easy to mix them up. Then you can lift the back of the tank more and disconnect the electrical connector. Then there are the two fuel lines that have quick connects that you pull back the plastic collar and pull off. They are supposed to shut off but have been known to drip a little or a lot so have some rags ready. Then you can slide the tank back and lift it off. That's from memory as I have not done it recently but I don't think I forgot anything.
