I've yet to see a Japanese badged machine that didn't have a provision for "sideways" adjustment of the motor. However it looks like the bend in the bracket limits the adjustment needed. Turn the motor pulley around. The motor no doubt has a flat milled in the output shaft to accommodate some adjustment to the pulley. If the shaft is round, the set screw will provide enough purchase on the shaft to hold it. After you turn that pulley around you might have to adjust the motor on the bracket to line it up. No elongated holes? Grab a file and make some.
