Cleaned carb - now bike won't start?

I cleaned the carbs in my 1982 Honda Nighthawk 450 and now the bike won't start( though it will turnover). The red oil light also comes on while I'm not pressing the ignition.

You turned On the Key?

The red light means it has no oil pressure, go figure, the engine isn't running.

Check fuel flow to the carb (easy, disconnect the fuel line to the carb and turn the petcock to ON).
