First Motorcycle, Changing fluids?

Hello, i just bought my first motorcycle. Its an 84' Honda vf700s, 4 cylinder liquid cooled. I was advised by the previous owner to change the fluids before i tried to ride it, because it sat for 2 years. I work on cars for a living, however have never owned or worked on a bike. I probably sound really stupid, but gotta learn some how right? I found the oil filter, dip stick & drain. There is another cap, im not sure if its the oil filler? Or if i add threw the dip stick hole? Also, does any1 know if the trans & oil share the same oil on this bike? And finally, how does one go about changing the rad fluid? And heres one more question… Sorry… Is there any other fluids i should change? This is my first bike sorry if i sound like a beginner
