CB400F Ignition Switch
« on: February 09, 2018, 07:19:12 PM »
One of the issues I had when recommissioning the bike,  was the ignition cut out a couple of times on the initial test rides. I have dismantled the ignition switch, and noticed that the white plastic part with the electrical contacts bit at the bottom of the barrel part, has been subject to heat, presumably from internal corrosion.  The result is the plastic part is melted!

Does anyone know if it's possible to just get the plastic part, or do I need a whole ignition switch, also is the DSS part interchangeable, in as much as I was thinking of buying one just to get the white part, thereby allowing me to keep the original barrel part and keys.

Hope this makes sense.
Thanks Dave

I don't think they are available as a separate item.I will look in my bits & see if I have anything.

To give you more options, the 550F1 &550F2, 550K3, 750F1, and 750F2 all use the same ignition switch as the 400 Fours.

Finally got around to ordering the repair part for my original lock barrel  and it's the wrong part doh! I am currently using the D'S part, but would prefer to go back to the original key.

The plastic part that arrived is the correct 5 pin connector, but has three tangs to locate it in the ignition barrel, regrettably my barrel only has two. Also the plastic part is a mm or so to big

I will take some photo's tomorrow, but in the interim, can anyone steer me in the right direction ir shed some light on the matter?

Thanks

There are two types of these, the one you have in the picture is a early one.

Two types of barrels and in the back of my brain, I am sure I tried to fit a later plastic part to a earlier barrel and it never fitted. There are so many different repro ones of these about, that it is hard to match the parts.
Is your original key, with or without a plastic cover ?

No original keys were with bike, so I ordered one off the barrel number.

Ever since recommissioning the bike  the switch was intermittent, on inspection the innards had sort of melted,  so I went for the DS unit.

I then I ordered the repair kit. It wasn't a great deal of money,  however I would like to go back to the original item, as genuine Honda keys are still available, as well as the convenience of having just one key for all locks.
