My ancient 83 Honda Magna 750 will start up like a charm in the mornings, but when then when I'm first checking things out before the ride, most times my left and right directional lights don't work.  Then, after riding 5 or so miles they start working, and are good the rest of the day.  Anybody with any idea what that's all about?

Thanks Rev!

prob your flasher going bad

Pull the lens covers, clean the bulb sockets with isoprophyl alcohol then apply a light coating of electrical grease. This should fix your problem.

Thanks guys!

Got to agree with everything so far, Corrodided bulb socket, mositure, blubs going bad the vibration resets the bulbs.
