Book Excerpt: 1978-1984 Honda CB750, CB900 DOHC Fours Repair Manual


  1. Before any dismantling work is undertaken, the external surfaces of the unit should be thoroughly cleaned and degreased. This will prevent the contamination of the engine internals, and will also make working a lot easier and cleaner.

    A high flash point solvent, such as paraffin (keronsene) can be used, or better still, a proprietary engine degreaser such as Gunk. Use old paintbrushes and toothbrushes to work the solvent into the various recesses of the engine castings.

    Take care to exclude solvent or water from the electrical components and inlet and exhaust ports. The use of gasoline as a cleaning medium should be avoided, because the vapor is potentially explosive and can be toxic if used in a confined space.

  2. When clean and dry, arrange the unit on the workbench, leaving a suitable clear area for working. Gather a selection of small containers and plastic bags so that parts can be grouped together in an easily identifiable manner.

    Some paper and a pen should be on hand to permit notes to be made and labels attached where necessary. A supply of clean rags is also required.

  1. Remove all traces of carbon from the cylinder head using a blunt ended scraper (the round end of an old steel rule will do).

    Finish by polishing with metal polish to give a smooth shiny surface. This will aid gas flow and will also prevent carbon from adhering so firmly in the future.

  2. Check the condition of the sparking plug hole threads. If the threads are worn or crossed they can be reclaimed by a Helicoil insert. Most motorcycle dealers operate this service which is very simple, cheap and effective.
  3. Clean the cylinder head fins with a wire brush, to prevent overheating, through dirt blocking the fins.
  4. Lay the cylinder head on a sheet of 1/4 ince plate glass to check for distortion. Aluminum alloy cylinder heads distort very easily, especially if the cylinder head bolts are tightened down unevenly.

    If the amount of distortion is only slight, it is permissible to rub the head down until it is flat once again by wrappig a sheet of very fine emery cloth around the plate glass base and rubbing with a rotary motion.

  5. If it proves possible to insert a 0.10 mm (0.004 in) feeler gauge between the glass plate and the cylinder head, the head is beyond the service limit for distortion and remedial action must be taken.


Haynes CB750 Honda Custom 1982, Owners Workshop Manual. definetly needed for the bike that I purchased last May. Have not owned a bike for 20 years and picked up a good 1982 750 Custom. Having not owned a bike for a long period of time I was in need of a good detailed manual and I found it with Haynes. Thanks.
