It is a lot more intimidating than it actually is.
Undo the nut holding the negative cable to the engine case. 12 or 13mm, I believe. Pull the battery cover downward from the top. Undo the screw/bolt that holds the strap on. Remove the strap. Disconnect the positive battery terminal (after you are sure that the negative is cleared and dies not touch anything grounded). Pull the battery out. Should take you about 5 minutes, not too hard at all.
Occasionally I am asked why I ride a Harley.
"Ride one and you will figure it out."
I am also occasionally asked why I am a Christian...
One day you will figure that out, too.
