HELP not starting

This is my dad’s 82 Honda Goldwing 1100GL. We bought it in the winter as a project bike, it needed some light repair work but ran fine and started on the starter motor without a problem. Now comes our problem. My dad just finished polishing some parts and repairing the radiator (the bike did stand a couple of months without spark plugs and without the camshaft coffers). Know the starter wont turn over even when installing a brand new starter. Just now we tried to start it by running and releasing it in second gear but the bike wont start. It does fire sometimes but doesn’t start, the bike has fuel, spark and air and ran great before putting it away. Can somebody help us?
