    1978 CB400A Parting Out !

    Hi Folks.

    ANNOUNCING :

    I have a 1978 CB 400A with about 27000 miles on it.
    I had fantasies, (Delusions?) about fixing a head gasket oil leak,
    which I started to repair and had every intention to do this to completion almost 2 years ago.

    Got the head off, disturbed the block to case gasket, then it got too cold to work on it outside.

    I did not protect the case opening too well and am afraid the bottom end got contaminated enough
    in that the cases have to be split, the crank removed, cleaned and appropriate area cleaned.
    (Spins just fine though)

    In fact, ran quite well except for said oil leak.

    I got new rings (AND TWO 72mm ring compressors, meant for a Triumph!), complete overhaul gasket set, piston circlips to do the job..

    Was going to have a friend in a truck repair shop who is an engine whiz do the overhaul, but he had to shut down his business.

    I had to get my bike out and took it apart down to the frame.
    It is now apart in my bedroom closet.

    I am keeping the wheels, tank and side covers and seat as they interchange with my other 400,
    A T2 in near spotless shape with only 9000 miles on it.

    I've got good instruments, headlight assembly, 2) taillight assemblies, wiring harness, airbox, front and rear fenders, 2 fork tube assemblies, though I think the left one has a leaking seal. Front brake caliper and hose, triple trees
    disassembled engine, (including honed cylinder) starter, frame (complete with CLEAR TITLE!), brackets, footpegs.

    A complete exhaust system including power chamber and new gaskets.
    (one muffler, don't remember which one, has some scratches/scrape on it from a minor fall)

    The headpipe chrome is shot, but can be easily polished smooth and re-chromed.

    Etc.

    Now I know what you are thinking, lemme see the pics, which, I understand you want to see before buying..
    I need to get another digital camera to make (stolen from my car!) you pictures.
    This is going to happen soon. (within a week)

    I am going to ask for pricing similar to EBay, but 10% less to twins forum members.
    I am not going to take apart individual components from the engine or trans.

    But I cannot be 100% certain I was able to hold on to everything small and loose from the engine that I took apart.

    Especially the carbs, which were partially (10%) disassembled.

    I would prefer to sell it all at one time, but parting it will net me more money,
    But I will have to do more work shipping etc.
    Unless some one gives me a pretty good price for the whole thing.

    (In which case, you pick it up, I'll help you load it. I'm in Paterson, NJ)

    So, feel free to ask me for what you need and I'll try to get you pics, condition, details, and price and shipping costs.

    I could use the change switch. How much do you want for it and how best to get together . Thanks, Bill H bhuntingt@roadrunner.com

    What is "the change switch" ? Are you talking about the gearshift indicator that sends a signal to the dash light to light up neutral, low or high?

    The change switch sits by the oil dip stick and under the right carb. Yes It tells the bike what gear it is in. It also increases the rpm when the motor is put in gear to keep it from stalling.

    I just completed a major overhaul on my 400a to find I cant ride it do to a bad change switch.

    Thanks Bill

    Peejay the change switch does three things. One, it wont allow the bike to start in gear. Two yes it tells the bike what gear it is in . Three, because this bike has an auto trynny when put in gear at idie it pules the motor down because of the load. The change switch sends a signal to the idle stabilizing circuit whitch incerases the timing from 7 degrees to 12 degrees and the rpm goes up about 600 to 800 rpm at idle. My switch is telling the bike it is in 2nd when it is in neutral thus not letting it start.

    No luggage rack, just the grab rail where the rear turn signals are attached. And I do have that

    Would that be part # 35752-417-013 ? If so, I'll try to look for it later.
