By the way, does anyone know what this front end come off? 

Much it seems is being made of the fact that today my special oil for evil ancient petrol burning classic motorcycles from the era of unlimited pollution will be delivered to me on an electric vehicle. Are they trying to tell me something? 

What does that loop on the right footrest assembly actually do? 

I spotted this oil temperature gauge for the CB400F on the Yamiya site, if my guess is correct it fits where the dipstick otherwise would sit. Has anyone got one, is it worth investing in? https://www.yamiya750.com/index.php?main_page=product_info&cPath=179_281&products_id=4119

I've got a seized clutch adjuster bolt meaning I couldn't fit and adjust a new cable as per book. My clutch is working ok but engaging rather late. My efforts to release the clutch adjuster bolt from it's hole in the clutch cover had me go blue in the face before... Banzai ..I had twisted clean in half a socket reducer. 
Thing is maybe this had saved me from stripping the thread in the clutch housing itself. The question is if that ends up happening when I get this sorted can it be fixed with an insert?

Today I got Elen, my beloved 400/4 back from her engine rebuild  . It took a while because of unforeseen things mostly, but what irritated me was that from the start I asked them to check the condition of my primary chain, which they said was ok when I rang in. But later they rang me to say they had to open her up again because the more senior mechanic from their main shop said the engine still had noises that can't be ignored, the primary needed to be changed.  Also the clutch cushes where worn with too much movement. Well, I got a primary from DSS and a whole nice condition clutch from Steve at 400four bits. Top gear on countershaft had wear in it but after discussion on here I decided not to pay about £300.oo and wait about two more weeks for this item, I never had trouble with top gear btw. A leaky carb was also dealt with, but the carb repair kit I ordered from Legend never turned up, so I gave up and got one from DSS, that got here quick thank gawd, the other kit remains in transit or something.
Well... I happily went to collect her, and I was told they had done some work on the tail light too, I could see that already, after all ... it was upside down!  Embarrassed mechanic put it right for me. That said she now sounds and feels great, rejuvenated even. When I get home I get the feeling someone was definitely in a hurry to finish up though because something didn't look right, the oil filter housing is on sideways, it was sort of smiling at me.  mmmm... surely it can't do any harm if I plain leave it like that a while? The cost of the job was £700.oo, the parts I bought myself for around £500.oo.

Can some kind expert please tell me the proper name for the cog arrowed in the supplied image? The guy at the shop today wasn't the mechanic and he couldn't tell me for sure but my issue seems to be with a second gear item rather than a third as discussed in an earlier thread.

Has anyone got a 3rd gear dog for a CB400F for sale?
