Lots of stuff screwed on to the bike over the last few days. Clocks, headlight bracket, coils, shiny shiny mudguard (Bertram's, from ebay if you're interested). Starting to look like a real bike now!

The tank it came with is currently at the blasters. I gave them the instruction "take the paint off gently". I think what will happen is they'll sweep it back into a bag for me to come and collect at some point.

Feel like the engine is looming!

Some progress - I couldn't resist putting the tank in place and lightly treating it to a bit of Tcut! Then I stopped gushing and fitted the rear mudguard, grab handle and indicators.

What. A. Palaver.

Mudguard was a repro, chrome in the threads meant I couldn't screw anything in. Tried to tap the thread out using guff tools made of Chinesium. Fail. Temper tantrum. Next day, with a proper set bought locally it was a doddle and I was much happier. Because I got the handle from DS, it's predictably not a proper fit (for a 750 iirc?) but looking at it, if it met the frame rather than the indicator bracket it would be flush. If I removed some rubber from under the mount it might actually look a little nicer. Project for a summer evening I think.

Made a loom for the rear lights from the old main loom, I had exactly the right amount of cable left in the correct colours, which is a coincidence that makes me think I should buy a lottery ticket at the weekend!

Just the rear light to fit now and I can fully test all the electrics and finally get busy on the noisy bits. ;D

It's getting there.
I use auto glym vinyl and rubber trim restorer on black plastic parts like mudguards and tool trays\lids. I leave it on for a few days to let it soak in before wiping it off. Everything comes up like new and the finish lasts despite washing.

Julie your indicator stalks are different to mine, they're chrome and look like they'll wobble about a lot less!

Those black brackets look like they're from a 500.

Julie, my brackets are the same as those on Sprockets bike. These are the brackets that were impossible to obtain new or s/h. I searched everywhere for a couple eventually getting a couple from ebay that need repair to the earth tangs. DS is (was?) making reproduction brackets when I last looked.
Sprocket, my rear handle looks the same as yours on both my original 400/4 and the one I restored a couple of years ago with a pattern handle.

Yeah I looked at the DS pattern stalks and the price made me purchase a tin of P38 and Hammerite! All the books pointed to them being OEM too, although as it happens my bike was a bit of a bitsa and I don't really trust anything!

And the handle. It's ok, but as previously highlighted, the 400 and 750 handles are the same length but the 400 should have a slight twist in it, to make it sit parallel to the frame. I suspect the 750 one mounts directly to the frame, where the 400 uses the indicator stalk hole.

I must admit, becoming nerdy about these things is actually fun.  :D

Is the mudflap on the front fender something that is supposed to be there and can I get one if it is?

They we not fitted as standard although a few people had aftermarket ones fitted usually with 'HONDA' logo's in white. I had one fitted on my first 400/4 in 1979 that I bought from Speedway of Acton (long since gone🙁). My mates called me an old man so I removed it after a while along with the huge barn door fairing, white fibreglass panniers and matching top  box.

I might restore the flap and fit it, it's got that 'rally' look to it, and I do love me a bit of group B...
