Trying to find a2 replacement counter weights for kam ddx 750

Balance the stylus, then calibrate the counterweight to 0. Then turn it counter clockwise to 2. For the antiskate knob, set to 2. Use the inner numbers for an elliptical stylus, use the outer numbers if you have spherical stylus. Hope that helps, feel free to ask about anything :)

the counter weight twists off.

1. Check the fuse replace with same amp fuse if blown
2. Check the 110v/220volt option.

When did it quit working?
Lighting storm,drop it
any more clues?

Pull the unit out from the wall and unplug it. Remove the back panel and check the counter weight (looks like a cement quarter round cement block), spider pulley and belt. The counter weight is attached to the top of the drum and can loosen and fall to the bottom damaging the spider pulley. If the counter weight is firmly attached to the top of the washer drum and the belt is attached to the spider pulley and motor, remove the top cover and lower front panel.
With any luck the counter weight knocked the belt off. If you are unlucky the counter weight broke the spider pulley.
Here is a link for parts.

Check to make sure the drum springs and shocks are attached to the drum. I hope you only need to bolt the counter weight back on and no other damage to the machine is found, you should get bake to business in about 40 minutes.

Removing the counter balancer would be the same as lightening up or shaving weight from the flywheel. You would definitely get more vibration. I can not tell you if it would be too much or not. Vibration can be dampened by adding weight to the handle bar ends and foot pegs. Revving the engine higher could cause damage. The simplest and easiest way to gain acceleration and horsepower on your motorcycle is to just get a counter shaft sprocket that is one tooth smaller than the one you already have. A smaller sprocket will give you faster revs and quicker take off with out the additional vibration and other associated problems.

If your are speaking of the total counter of the machine, the main counter when you press the "utility/counter" key this can not be reset except in the case of replacing the main board.

This is a simple repair. All that should be required is to remove the back panel to access the counterweight. I've performed this repair on several occasions. Loosen the bolts that sandwich the weight between the mounting plates and the whole weight should slide out of its mounted position on the back of the tub. Insert the new weight by sliding it in place and then re-installing the mounting plates and bolts. Tighten until snug. Do NOT overtighten as you may crack the weight. I hope this helps you.
