HondaCB650

My front wheel spokes go "Ping" when rolling my bike around. Jacked it up, spun the front wheel, its straight. Tapped the spokes with a wrench, all had the same pitch and were tight. What the heck? Any advice?
Thanks,
Todd

Wheel was really out of alignment. I just slapped the forks I rebuilt back on and paid no attention to alignment or anything. The bike was putting sideways pressure on the front wheel.
