New thread on cylinder head and remake of Exhaust Ring Nut for an old BMW Motorcycle.

A customer with an old BMW Motorcycle came to us with a problem. The thread, to attach the exhaust pipe to the cylinder head, was completely worn and damaged. He wanted to keep the original cylinder and hoped that we would come up with a possible solution.

After evaluating the situation, and making a technical drawing, we found a way to repair it. First, we resized and remade the thread on the cylinderhead itself. Then we went ahead and made a new exhaust ring nut that would fit the new thread and the exhaust pipe.

Result : a very happy, satisfied customer!
