Topic: Assembly and Discussion of the Right-hand Switch (a rebuilder's guide)

[brettster26]

I dont want to steal the thunder from this thread but I was wondering if anyone could help me out with how to get the left hand control on the bars without running the wires through the bars... Figure this would complete the post if this question is answered.  I believe the right hand control has a cut out so the wires fit through the bracket without having to go through the bars.

Thanks

Well, to avoid having to drill the bars and route the wires internally, you pretty much need to notch the switch housing.  I know this has been done successfully by others but I've never done so myself.  Note that you'll still need to drill a hole for the control unit's locating pin which keeps it from rotating on the bars.

 Also, you didn't mention what bike you're riding; I believe some of the later "F" models ran the wires outside the bars, but the "K" bikes run them internally.

My Bike is a 75 CB 550K  The handlebars that were on there when i bought it were Ape hangers and had the wires through the bars.

I am not talking about the two that hold the case halves together, I am talking about the little ones inside.  I am guessing they are JIS, I didn't have my JIS screwdrivers until after i buggered them.  Ace is kind of rare around me.  The Fastenal near me won't break open bags anymore.  I guess I had them break open too many, lol.

The screws are NOT JIS. See the little punch mark on the top of the screw? That means that it is ISO (International Standards Organization) not JIS (Japanese International standard) Changed around 1965.

I appreciate your post as I work thru re-building a right hand control.  I have a 1976 550K and the wires had been cut or broke loose inside the housing when I bought the bike.  There are Five wires going in the housing.  I know the two that go to the kill switch and the yellow/red that goes on the end of the start button but I can't tell where the other two wires connect.  I will be re-soldering them all once I identify where the last two wires connect.  Please let me know how they go, Thanks, Jeff

Any idea where I can get the "start" button switch assembly?  I've tried david silver and yamiya with no luck, and from what I gather, the people on ebay seem to only sell the button and spring and not the plastic part in the middle of the assembly or back plate you need to solder the yellow/red to as well.

I do have a slight solution that I used on my starter switch.  I have a 75 cb750k that has the on-off switch on the right control for the lights.  I bought what I thought was the same one as mine but I believe it was a 76 model (modular connector and no on/off for the lights).  It is all metal like the 75 and prior but has the later headlight always on and headlight kill starter switch setup of later models.  The upper half of the switch did not have the on/off for the lights.  What I did was take the lower half of the switch housing from the 76 with the later style switch in it and simply unsolder the factory wires from both and re soldered to the other one.  Using the 76 housing I just did not solder anything to the 3rd position which is used for the headlight kill when the switch is pushed to the start position.  I physically can not tell them apart by looking at them (except the bottom which has a kick out for the larger switch) and have the more reliable later switch, and still a matching full metal housing.  I didn't even have to touch the top housing at all during this or remove the wires from the bars, just loosened the center clamp and let the bars flip upside down to get access.  Took me all of an hour to split the switches, undo the throttle cables, unsolder the old lower housing and re solder the wires to the newer one and put it all back together.

As far as the JIS internal screws go, I think I have found a supplier, but he is in the UK. He will send me 80 of the screws for free if I pay for shipping...but so far that looks cost prohibitive.

It sounds as if you're basically looking for everything but the housing?!  I don't think any of this stuff was ever offered separately, though I do believe the button and spring may currently be available through the vendors.

I think your best bet would be to pick up a used control from Sohc's very own "parts for sale" forum, ebay or a bone yard. I've seen some pretty decent switches on ebay that have gone for half the price of a new one from Yamiya.

Alternatively, you could always advertise for the parts you need in the "Bikes and Parts Wanted" forum here on the site, and someone may be able to help you out!

Good luck!

Interesting... All kinds of possibilities popping up!

Sooo, just how much does the sonuvabi gentleman want for shipping? Maybe we can get a fund going?

Thanks for looking, Accolay!

Not really, the right hand assembly consists of the kill switch assembly, the on/off headlight assembly, the starter button assembly and the housing itself.  I'm just looking for the button assembly bit.  I'll post a wtb bit on the forum here soon, seems like a logical place to start.

great wright up and was a big help with my build thanks

[Accolay]

I think I want to measure the screws again. He was going to send me 40  of each 3x6 and 3x8. Shipping would be via one of the major carrier- UPS, DHL, FedEx, or TNT. Somebody would need to open an account so he could get it billed. I looked at the shipping rates, and they seemed mighty expensive for little screws.

Hey guys,

I am new to the forum -this thread helped me out a ton with the right hand control when I was switching out the handlebars on my 1974 Honda CB350F (pictured below). However, I still need to put back together the left handed control and it's been so long since I took it apart that I can't remember where all of the springs and ball bearings go. If someone could please describe to me and/or supply a couple photos of the inside, that would be great! Thank you in advance.
