Our original German motors are disassembled and, unless tested with high compression, they are rebuilt. Then meticulously reassembled with many new parts and components usually including new carburetor and air cleaner, battery, spark plugs, seals, etc. Pertronix electronic ignition systems are always installed to eliminate the old faulty and frustrating points and condenser distributor systems. All motors are bench tested and run for initial break-in prior to installation.
