Found a Breather Chamber on e-bay for under £20. So I will instal that. I like the idea of having another genuine part on the bike. If I am super clever I will see if I can copy the design into 'blender' and maybe have it 'printed'.

In this image, fig.1.1 the part [2] 'Breather Case'should be below my Air box. I dont have that, there is just a wee hole, one that is too small for the hose coming out of the top of the engine block. I am using a hose with 11mm Inside diameter x 16.5mm Outside diameter for the part marked [1] Breather Tube, in the diagram.
Question;
Is the part available anywhere?
Should I care that I otherwise vent to the atmosphere?
Could I fabricate one for a 'yoghurt pot' so to speak and achive the designed effect?

Geat tip Eldric.
That looks a neat idea, really easy without any tool if you have no rear wheel or mudguard fitted - as you say an absolute pig otherwise.
I'll look at making something like that next time I have to do it in situ. Did you look at using a long bolt instead of two long screws or does that make getting in situ impossible?
I just don't have bolts so used what I had.

Time to give to the forum, I was looking at posts and videos about getting the air box onto the carbs after the carbs were installed. I tried yesterday, even with my heat gun and failed.
Today I made a tool out of wood and fitted the box very quickly.
Here are a few photos of what I made.
Oval shape, using the metal link part that goes into the airbox as a pattern.

It is one and a half inch thick, give or take...

In situ ready to put some pressure on the, well that part that never goes over the carb to easily.

Wrench to apply the pressure.

So, one hand on the wrench one on the screwdriver and I was pleased

If you want to torque every thing 8 ftlbs to 50 ftlbs, leave out the alternator, primary gear and clutch nut and 8 ftlbs to 20 ftlbs will do.
Those 3 are normaly done to BT.
I don't anticipate ever replacing pistons myself but I would be ok replacing gaskets in the head. I also would not be touching gear boxes, so with that in mind, what range may I need?

3.2 is a bit big, better using a 1/16 drill bit shank preferably new so no damage
OK so about 1.5mm, I may have a dril bit, if not the guage will do it

Don't worry too much about vac sync gauges, you can set the slides very, very, very close by manual bench sync.
I may have just done that bit with 3.2mm feeler guage. I also think I can afford that wrench if it is the Britool AVT300A

My trusty Britool 1/2" wrench was too big so I bought a 3/8" Draper. Good tool but the Imperial & Metric Scales are in Inch-Lbs or Newton Metres range is 10-80Nm. I had to do a conversion for all the settings in my manuals.
Ha, see, I didn't even think about all that maths! Glad I asked before buying.

I want to do more work on my 400f myself and I think I want a torque wrench and a carb synchronizing kit.
I keep looking online and get overwhelmed with choice. The other issue is I don't really know which is best overall for this specific bike rather than ‘the best make’. No good having a best make torque if I can't perform most/all jobs on my bike and end up buying another one.
I also thought I wanted a single gauge, four into one, sync kit, I could be fooling myself though. I liked the idea that all four carbs were being tested on one gauge.
So, if you can recommend a good torque wrench and carb synchronizing kit I can get started on being a shed mechanic and maybe even get a second (His and Hers) 400f.

Welcome to the forum. That's a nice looking bike. Remove the gaiters though, they were never fitted to 400/4's.
That's a good plan, more shiny bits. They were fitted by previous owner I guess and no, this will not be out in the rain so off they will come.

OK, got that image loaded, lets hope fitting carbs back on the bike is just as easy.

OK, a funky attachment button to get an image loaded, lets try that then

Just joined the forum, mostly been reading before and now I have decided to become my own bike doctor I thought I best join too. I have a very nice Red-1975-CB400f and it runs. Currently, I am cleaning/inspecting the carbs as I suspect shenanigans in there. Not being mechanical in any way whatsoever I am mostly on a discovery tour whilst doing this. I would stick a photo of the bike on here but I don't see an option to embed the image, just link it aand I don't have any images online. So, just imaging a very shiny, Red 400f and you wil be close...  The bike and I are currently living in Penzance.
