It's possible you have a CB350 Four speedometer fitted and that's easy to identify. Attached an image the both, one on the left the 400 Four one and on the right is 350 Four. In fact you don't need to remove the speedo to check, the trip knobs are different and the the 350 one is secured by a tiny screw while the 400 type and pressed on.
It's more likely to be a speedo from a CB250 or a CJ and that on the underside looks the same. However as both the CB350 four and the CB250 share the same front wheel size as the 400f it should be accurate. Best to use the term accurate loosely as most read 10% fast.

The covers are stainless steel Ted and not chrome. The covers fitted to the CB750 Fours are steel chrome.
If you had sent them with your gauges I would have polished them. Takes five minutes on the bench mop.

Assuming the gauge design is the same as shown is the image you will find after removing the face there is a small 5mm brass nut. If you unscrew that you will be able unscrew the damper bush. You need to take note of how much thread is protruding from the brass nut to ensure it goes back with the same amount of thread
visible.
You can then 'dribble' some silicone fluid down the needle pin and put some on the damper bush. Check that improve the damping effect. There is another type of Seiki mechanisms where it not possible to unscrew the bush. Although the mechanisms appear the same so you have to either remove the front of the mechanism by folding back the tabs that are formed from the frame or drill a tiny hole in the damper body and put some silicone in it. Reseal the hole with some mastic. Obviously great care is required, a centre drill bit and a hand drill.

You don't mention whether the gauge is ND on Seiki. The filling of the damper can be different between the two types and the on some of your machines on your profile if could be either of the two types. You silicone you need is 100000.

The part number for the foam cushions is 37242-323-701 and fit both gauges. The mounting plates are stainless steel.
Rusty gauge bases cause the cushions to stick to them. The bases were zinc plated with the passage of time the plating has detreated and that needs to be addressed.
Re-plating is the best option but can be painted once the rust is removed' If that's the preference tape over the lamp apertures. Most certainly you don't want rust flakes getting into the gauges.

By some coincidence I had to replace the master cylinder diaphragm on my 400 four early this week as the original had rotted and almost falling apart. I'm assuming that the master cylinder is the same as fitted to the 500 four.
I ordered the genuine diaphragm part number 45521MJ6006 and plate 45520300000, the plate is nothing more than a large plastic washer. The purpose of the washer is to secure the diaphragm in the master cylinder cap as it fits above the threaded portion of the cap.
I'm absolutely sure that the master cylinder and cap are original but the retaining washer although genuine is too small so it won't retain the diaphragm in cap above the threaded part. The original washer can't be used because the lip on the new diaphragm is smaller.
This means that when the cap is removed it leaves diaphragm in the cylinder. I don't think it's important but if it is the only remedy is to make a plastic washer using the old one as a pattern with a smaller hole for the new diaphragm

I'm sure there are Members here that are a 'dab hand' at the art of soldering. I'm using one of those cheap Draper ones but looking to upgrade so any recommendations appreciated.
Usually I'm just repairing looms so just electrical connection and that's not too frequently. Then there's the best solder to use, what I have came from Maplins years ago and was made in Asia.

Just to add to the list compiled by Tricky Micky the trip grommet is missing.

Paul G mentioned Memo, I've just received a pair of gauges from Canada marked 'for repair & return'
arrived here without a problem. No evidence Customs had looked in the box. So it might be the case that no duty is payable is these circumstances and shouldn't be as it's not a purchase.

I ordered some gauge faces from Marcel earlier this month and no VAT or Duty on delivery here so whether this was a 'one off' remains to be seen. I have another order on the way here so I'll see what happens to that one. It maybe that items in a jiffy bag are ignored by customs.

Those gauge covers are the same as those supplied fitted to the replica gauges sold by David Silver and others. I didn't know they were sold separately and supplied with the foam cushions, Clearly the seller thought they were chrome as original ones but as Phil mentioned they are stainless a better option as the chrome on the originals was never too great

It's a good plan to check the warning lamp lenses are secure on these replica covers. I bit on extra glue around the edges of the lenses is worthwhile.

Yes that's the damper, it's aluminium and the shaft inside it is brass. A 2mm drill seems the best size to use and the best place to drill the hole is in the middle. This does need great care as you don't want to drill into the brass shaft. You also need to remove the mileage counter if the drill slips you know where if will go!
The mileage counter is very close to damper so when the hole in the damper is sealed if has to be close to flush otherwise it will touch the counter.

Hi Simon,
The easiest way is to drill a very small hole in the damper ( I use a hand drill ) of course the damper pot will try to revolve so lock it with a small piece of wire to the speed cup rest tab. Add some 100000 silicone oil, it's quite thick so push it into the hole and turn the speed cup to spread the oil around inside.
Takes a while before you will see the damping restored and try not to get silicone oil on the hairspring. Seal the hole with some mastic.

You will find a selection of variable power supplies here www.gaterosplating.co.uk you need one that has a fine voltage adjustment, a digital display and goes down to point 5 of a volt. I bought one on fleabay. Ash is the best one who will know which is best although he probably made his own.
