I took 2 measurements each time. Cleaned them in between and made sure it was the correct direction. I've ordered some blacks anyway as I need to do an order at DSS. Just need to wait for that and some more plastigauge. I'll take pictures next time too.

measured again and the clearance looks like its more along the lines of 0.038mm 0.050mm 0.050mm 0.025mm. I might order a set of black and see what that shows.

I think you are missreading the plastigauge chart or the micrometer ifvit was the gap you say you would probably feel play

I'll give it another go tomorrow. The measurements for the mains went fine, unless it was just one of those days today.

I always go middle but I can't see that 14.75 would be a problem.
If they are new shells then it should come in spec no problem.

Yeah new shells just a big clearance.

Im just surprised at the clearance. The Haynes manual says 0.018mm to 0.048. I might need to go to black.

The Cs on the conrods are the weights, the only thing that matters about that is they are all the same.
Take the As from the webs and your conrod shells are A2, A2, A2, A2 which is Yellow.
Using Green or Brown should give you tight tolerance. Are you just tightening them or torquing them?

Im torquing to 14.75 lb ft.

It says 14.5 - 15.9. Should I bo going higher? I always go middle to lower end of the range.

When you say 'my con rods are C2 C2 C2 C2', is the C and 2 on either side of the conrod or have you got the Cs from the crank?

Yes, the C and 2 are on either side of the conrod, I don't know if they're relevant to the graph. My web codes are 1 1A 1A 1A 1A and the crankcase codes are BAAAA.

Did you measure the crank Lukas, it may well be very worn.

If I'm reading the wear tolerance on the graph correctly, the wear is within the tolerance. All below 0.016mm

My green and brown sets of big end bearings have arrived and I have measured them up, and once again its not going to be as easy as I hoped.

Im not sure if I've read it wrong but my con rods are C2 C2 C2 C2, my plastigauge measurements are 0.050mm 0.050mm 0.050mm 0.038mm. And to throw more confusion when measuring with the micrometer I get a clearance (32 - the diameter measured) of 0.0138mm 0.0163mm 0.0163mm 0.0087mm.

I measured with the brown bearings first and was surprised at the big gap. 0.050mm is too big what is the tolerance? The connecting rod chart is a bit more confusing than the main bearings chart.

True, but if i had said that he would have complained at the ocassional 3 days!

Im not fussed about delivery time. I'd just rather not pay over the odds like some parts seem to be.

I think im going to try yamira for the bulk of the parts. My 90% complete list is £274 from yamira +£36 postage or £492 from DSS Im getting a few things from DSS anyway because the price is negligible. And yamira seem to have a lot more seals and o rings.

Honda will order any part available in their european warehouse i have found, just takes longer

You can get 400 four parts through a Honda dealer?

What was the process like?

Not Kawasaki cush ribbers but Kawasaki primary chain, part number has been posted on here many times

Ahh I miss read you. Yeah I found the Kawasaki primary chain mentioned and have got one already. Not bad saving half the price!

Primary chain and primary cush drive rubbers, although cheaper to buy kawasaki primary from fowlers, also the special sealing washers for two of the head nuts

Cush rubbers are about £10 from yamira. What are the special washers?

Do you have the part number for the Kawasaki cush rubbers?

I've seen a few people mention that the typical full engine gasket/seal sets are missing a few things. What exactly are they missing? I've got it from here because of no stock in some other places https://www.bertrumsbikebits.co.uk/product/honda-cb-400-4004-cb400-4-cb400f-full-gasket-set/.

Is it worth replacing the cirlips? If so how many are there exactly?

What other small things do you normally miss?

I'm placing a big order with yamira so don't want to have to end up paying another chunk for shipping on a few missed things.

so far I've noted these in my google sheets file:
cam chain
Cam chain tensioner blade
Cam chain guide blade
Cam chain tensioner blade damper rubber
Camchain tensioner arm
Clutch lifter plate bearing
Cush drive rubber
Engine oil seal kit
Exhaust silencer to collector box gasket
exhaust downpipe to collecter
Exhaust No. 3 down pipe to collector box clamp
Exhaust No. 1 down pipe to collector box clamp
Exhaust port gasket
Oil filter
rubber damper
exhaust collar

I've only ordered from Webike in Japan. I have yet to be clobbered for tax/import charges. Service has been excellent. Some parts, however, are cheaper in the UK....

Yeah, I've spent my lunch hour putting together a spread sheet comparing prices, most are cheaper on yamira but a few are cheaper or negligible on DSS.

Some stuff is half the price from yamira.
