sometimes the obvious simple answer is the easy fix: is it possible you put the battery in the wrong way, or you got a new battery with the terminals not in the correct location? Or maybe a battery that is slightly too tall? As with car batteries, you can get motorcycle batteries with the terminals on the front with the + on the right or the left, and with the terminals on the top or on the side. On some bikes you spin the battery 180 so the terminals are towards the back.
If you are not sure what is the proper battery for your motorcycle goto www. batterysharks.com, and look it up by make and model and year - they will show you a photo of the battery that fits your bike.
the terminal screws with the captive square nuts can be a challenge it get started, because the nuts are not captive until you catch a few threads with the screws. Other than that, it should go together fairly easy.
Its also possible a previous owner replaced the battery wires with the wrong lengths / part numbers to repair wires that were damaged by a leaking battery.
