The first place to start is to pull off the front left wheel and check the plastic drive disc that is captured between the rim and the hub. Make sure it won't slip and the square hole inside isn't rounded out causing the square drive cable in the center of the hub to slip. Next disconnect the cable from the angle drive and make sure it isn't binding or skipping and then lubricate it. Check that the lower speedo support is not missing or bent. Make sure there are no sharp bends or kinks in the lower speedo cable, turn the wheel lock to lock and check in all positions. If these tips don't help you may have a bent cable or one of the ends is damaged. Pull the inner cable out and lay it on the floor. It should lay flat and straight, if it doesn't then it will whip when it turns causing a bouncing speedo needle. Lubricate and reinstall. Generally the problems happen in parts before the lambda counter, in the angle drive and lower speedo cable.
