Well the 1st prize goes to ......
Here is a pic of the LHS carb diaphragm. Not the best pic but...

Its a hole in the diaphragm.
I hope the spare carb diaphragm is still ok

Before I spotted the info on carb diaphragms, I thought a cheap test would be to switch the coils over and see if the RH plug became very sooty. There is only one condenser and if at fault would apply to both cylinders.
So with coils changed over and spark plugs cleaned of soot, it started fine and idles good. But on a 2-mile run, the problem still exists - unsurprisingly.
Anyway, the LH sparky is very sooty again. SO it's probably not the coils.....
Right, let's have a look at the LH carb......
I will report back

An update. Points off. Looks ok. Advance unit out and seems to be working. It's free to advance and spring back.
Compression tested. Cold engine, throttle fully open, I get about 150 (psi?) per cylinder. So they seem ok.
All back together and points set up as manual says. New spark plugs.
NO improvement. Still won't rev and in holding back. LH plug is very sooty and black.
Wonder if it's the condenser/coil.
More investigation required...........

If ordering points, I'd strongly advise buying original, not copies. Copies just don't seem to work as well these days.
Yup. I do this with Brake cables and clutch cables as well. Altho if DS stock an alternative, are they OK?. Anyway..... its now being prodded to see what's wrong.

Well, I have begun the investigation. Does a cb360 ever go pop. Apparently so.
It's a twin coil/points setup. All original as far as I know.
So a quick and simple test is to change the plugs. And with a new set of sparkies I went for a spin.
It's still unwell. So those points will be looked at next when it's cooled down. Maybe a set of points from DS is in order.
Time to check the advance units as well.

Maybe a bit late now but david silver does/did oem spoke sets for front/rear wheels for my cb360k0. Fitted well.

Hello, I have had this cb360 for 3 or 4 years and after its restoration have done some 3.5 k on it without any issues....... except for now.
It starts ok and pulls off ok but now won't rev over 5k in any gear. Seems fine in the lower revs. SO, before I start to investigate, I thought I would ask the obvious questions......
1. Blocked main jet?
2. Ignition Advance not working.? Stuck.
3. Points gone duff. Not looked yet.
4. Some other mysterious and daft issue.

I thought it was from those importers in Stoke-on-Trent. And usually for £200.

They are off a KZ750 twin. So, there are non to be had in the known universe. It's very tempting to try and keep/repair the originals.
Here is a pic of them.

They look ok when on the bike. But are not fit for purpose. There is an alternative..... at a price.
I would like to keep them on the bike, BUT I do think that while they mostly look OK, I bet they are rotten inside.
I suppose we all dream of keeping the originality. I agree that finding somebody to do the work is difficult.

Hello, I took these to an exhaust specialist here in Notts to see if they could be rescued. After 4 weeks the reply was NO. So I picked them up and trudged off home. I suspect they could not be bothered? but I need another opinion.

and the other one.

There are two exhausts. One better than the other. Are they worth bothering with??

I have to ask. The time is nearing when a new hip will be needed/done.
Is there anybody on the forum with a new hip and still rides their bikes.. I have 10 of the things but wonder if I should stop after the op. Maybe its time to call it a day.
Like to hear you opinions. I have ridden bike since I was 16 and was hoping to go as long as I could ride even if its a cb360 or honda 90.

All I do is lay the bike on its side with engine on some nice soft carpet or similar and undo the bolts and the frame lifts free. Worked on most of my bikes. Refit the engine the same way. Too old to risk a dodgy back to lift the engine out of frame.
Does not work on an MT500. But which sane person owns one anyway.

Likewise I have found pattern or not original parts to be fine. But maybe I have been lucky. I bought a new, not original, fuse box for my army bike....... but then just about anything will have done. These old jap bikes can be a bit picky. I always thought a DS pattern part should be a good replacement.... maybe I have too much faith.

Whilst its nice to have shiny bits on the bikes and I do prefer that, with 10 bikes I have gotten used to some bikes needing cosmetic attention but are in good mechanical condition and running fine.
Producing a "show queen" is going to cost a fortune. Its is a shame that its cheaper to get a repo item rather that repair/re-chrome the original. I doubt that will change in the future either.

It's worth looking at this
showing a 1972 CB350 in action - no idea on weight of rider or mods made to the bike but a lot of fun anyway...
I wonder how often that engine gets rebuilt. I have watched a couple of vids about the 350f... then do seem to rev well. But that might get a bit tiring after a while. Very much a country road bike. Now I was surprised to see the honda xl500r only had a drum brake on the front.... like the mt500 BUT has the kick start on the right side.......... MT500 is on the left which is a pain. A warning to anybody thinking of a mt500. If it still has the standard carburetor it will be utterly rubbish. They need one of the upgrade carbs to work fine. Then they are almost ok. Back to the 350F. DK motors have one for sale so I might try to have another look and sit on it again. The fat frog also has a first year one. Maybe its worth waiting for the Jan sales.
