This is what i have so far, only rotates one way on left click down, need it to do the opposite in the same script can anyone give me a hand?

using UnityEngine;
using System.Collections;

public class ArmRotation : MonoBehaviour {

	public float force=20;
	public float speed=10000;
	
	private HingeJoint2D joint;
	private JointMotor2D motor1;
	
	void Start()
	{
		joint = GetComponent<HingeJoint2D>(); // Get hingejoint
		
		motor1.motorSpeed = speed;
		motor1.maxMotorTorque = force;
		
		joint.motor = motor1;
		joint.useMotor = false;
	}
	
	void Update ()
	{
		if(Input.GetMouseButtonDown(0))
		{
			joint.useMotor = true;
		}
		if(Input.GetMouseButtonUp(0))
		{
			joint.useMotor = false;
		}
	}

}

Have you tried setting the motor speed to minus speed?

if(Input.GetMouseButtonDown(0)) {
    motor1.motorSpeed = speed;
}
if(Input.GetMouseButtonUp(0)) {
    motor1.motorSpeed = -speed;
}
