Wiring idiot here, starter switch has RY + B, diagram says RY + RG.
Am I right in thinking B connects into RG?
Well I connected the Black to the Red/green, with a little rattling I got the engine to spin on the button! Yay, success. That's most of the electrics figured out, just a few oddities to figure out.

I can do that,  cheers. All learning isn't it.

Thanks, I am pretty rubbish at understanding electrics but trying to learn.  The posts were easy enough to follow by the book. Yellow red has what seems to me a straight forward connection.  The black wire was just cut as you see it with no clear connection. (F2 btw) having a RG right there with no apparent use was distracting. I will endeavour to investigate further.

1 thats not the starter seitch its the sarter solenoid
2 need to know the colours of wires into the starter switch or button inside the LH handlebar switch
I replied to the wrong post 🙄. They called it a starter magnetic switch on the diagram, I have a spare RG right by it so made a mental jump. With check the switch assembly.

That brew looks tempting.

Never one to far away.

I will need to check that, I have an unaccounted RG right by  it, hence the mental jump. Apologies for the miss naming, I  read starter magnetic switch on the diagram.

CB350/400 / Re: Carb Rebuild - to do myself or send away?

Definitely do them yourself. I sell complete Viton O ring kits as all yours will need replacing. Use the existing brass ware. There are guides in tricks and tips on the forum of how to bench sync and set float heights, there are vids on Facebook and we are all here to help with advice. You can send the to Gerben for a full recondition / overhaul but it's not cheap. Have a go, you have nothing to loose.

Hi Julie,
I have have heard you refer to selling parts, where might I find this? Do you have a website?

Are they like these? These are jardine 4 into 2’s. As you can see the 2 and 3 cyl go to the left pipe and the 1 and 4 go to the right..


No, they are definitely 12 - 34, have them just about there now. The problem was side stand position mainly. .

I have mentioned before, photography and classic cameras are my thing. Very few people fix the things I use so I had to learn, I think nothing of stripping a 1920/30s graflex and rebuilding now. I earn half my income from it. I clearly had the ability when I was 20, just never believed I did. Still, the bike is giving me something new to do with enthusiasm.

I rode mostly in the 80s, I didn't have the self confidence, nor was I encouraged to learn anything mechanical. I took everything to a workshop. Here I am aged 55, doing my first build learning as I go. Full of stupid questions, reading and learning much from this forum and loving it. I have learned more about motorcycle workings this last 3 months than the whole of my previous riding life.

Same as the first, trying to reassemble several boxes of parts into something resembling a motorcycle.

Well I hid from the world over the weekend. Last weeks failed attempt to work out the exhaust made sense finally. Finished  cleaning the last of the carburetors and got them mounted with only a little blood and profanities.  Not easy those beggars are they! Oil tank, O rings seals and filter meant I could fill with oil and slowly start working the engine. Feels nice and free, promising puffs of air from the plug holes. I keep my expectations low but remain stoically optimistic, telling myself it's budget shed build so any victory is a victory!

Technically that's the right way to pair a 4 cylinder into 2, most that made them didn't bother but seem to remember Jardine promoting that as their selling point in the dim and distant past.

We'll find out though,  let us know how you get on.

Got at it again today, had a serious google of Jardine models and this on looked to do 1+2, 3+4. Finally figured out the down pipe positions and worked out with side stand removed it fits, will need a little massaging but it does work. Simplest solve would be a bolt on side stand re positioned. Keeping the ability to go back to original when exhaust replacement in the future. Cheered my weekend up properly.

I will and thank you again. I have glean much from reading back on stuff here. Regretfully my only contribution is asking questions. Be few days before I can get at again.

That is information that might be something,  thank you! Last week a pulled out a large bracket. Knew it was important, could work out what it did? Googled, read, nothing. Tonight research on the exhaust flagged it up as the muffler mounting bracket! Might be helpful too 🤣

As I said, novice!
