Did anyone manage to produce any of these switches in black? I am the proud, new member of the missing horn button club.

Good, I was beginning to doubt my sanity.

Finished treating the tank with Evaporust and it has done a great job of removing the rust. The before and after pictures, as ever, don't do it justice. I've put a mix of petrol and oil in for now and given it a slosh around. Once the clutch cover arrives all being well swap for the broken one and then a short test ride before the disassembly stage. Now it's fingers crossed that there isn't a nasty surprise behind the clutch cover.

Thanks for the comparison photo. I've had a quick look and tried changing the position of the spring, to no avail. I've looked at the exploded drawing in Ash's dropbox and can't see anything missing. So far it's a mystery. I've had to replace 2 fenceposts set in concrete which involves rebuilding a small brick wall so I've had little time. I'm sure I can wrap my head around it eventually. When you lift your footpeg, does it "click"?

I did that with the old nipple, when I was fault finding. I thought I'd try without as it is a new nipple, however I'll have a look at doing that if it keeps weeping.

Got the front brake working yesterday but I thought it still felt a little spongy. So I used the cable tie trick on the handlebar that I found on this forum, well 24 hours later it is much improved. There is a tiny amount of fluid around the bleed nipple and I have read again on this forum that it needs to be really tight. I have fitted a new nipple but I'm loathe to swing on it much more as I have given it a fair old tweak already. I'll keep an eye on it to see how it goes.

CB350/400 / Front Right Footrest
« on: October 25, 2020, 06:38:47 PM »
I took the right footrest off to gain access to the clutch casing. I was moving it up and down and it was clicking up into the locked position. After doing this about 3 times it stopped clicking and is now floppy. Can anyone tell me if something is missing or if the thin metal spring type thing is in the wrong position? If something did fly off then I 'll scout the garage floor again, but it would be useful to know what I'm looking for.

Yeehaw I've finally got the front brake working. I fitted a service kit to the spare, I think original, master cylinder. Now I have to tap in a new thread as I have removed the broken mirror stem by drilling most of it out. Could someone tell me what tap I need? Have sourced a clutch casing from 400 four bits. I'm concerned about what the thread might be like in the crankcase but that's for another time. Whilst idly moving the right footrest up and down as it is removed, it was clicking up and down nicely with a click in and out of the up position when suddenly it went floppy, I didn't see anything ping off anywhere but that's not to say anything didn't. Does anyone have a photo of one or a link to a drawing. Meanwhile, following in Macabthieles wake, I am in great admiration of the paint job on his, intact clutch cover. I must ask him how he did that super looking paint job.

Front brake still drawing air in from somewhere so currently on hold waiting for new washers and bleed nipple. I've also ordered a brake master cylinder service kit which will either go into the MC on the bike or the spare MC which I have now managed to take apart.

Petrol tank is currently enjoying a bath in 5 litres of Evaporust.

So spending some time looking around the bike and found that the clutch casing is broken, below the kick start. I've put in 3 images showing close up then moving out. It's a shame because it's the shiniest bit on the bike!

Had a quick look for a replacement but the one I have found listed as CB 400 f is different. Am I getting the name right, clutch casing, clutch housing. Is a CB 400 f different to a CB 400 F super sport? Below a link to the one that is clearly different.

Started cleaning the caliper and noticed some marks, sort of rivulets, under the paint and wondered if they were an issue, on removing the paint I don't think they are but have included an image if anyone has an opinion. Also included an image of the inside of the caliper and wondered if I should try to remove the hollow dowel to aid cleaning or is it best left in place. I gave it a bit of a tug with long nose pliers but it didn't want to yield. I think that its probably best left in place. New piston and seal arrived rapidly so is ready to fit once I have cleaned the caliper. Any recommendations on paint/prep welcome. Link to photos in previous post. Pretty much ready for a test ride once the front brake is sorted.

Front brake progress. Found that the upper brake line was also blocked, gave it the same treatment as the lower one to clear it out. Struggled to get fluid pumping down the lines and ended up using a technique from this site posted in 2009, using a syringe to pump fluid up which worked a treat. The brake worked but wasn't releasing its grip on the disc. Even got the brake light working. I know I shouldn't get so excited about that but it's early days. Next I squeezed on the brake lever and the brake pad started to move out and quickly the piston came out. The piston is badly corroded so I have ordered a new one with the seal.

Again short on time today but a quick update. Found that the lower brake pipe was indeed blocked. Soaked in hot water and pushed a guitar string through and hey presto it's cleared. It's drying out on the radiator now. Will have time tomorrow to move forward with this. Meanwhile I am learning lot's about impact drivers, great stuff.

Not done much since last post as I have been fitting a worktop in the utility room so than I can have the old worktop for a bench I'm building in the garage. The caliper bleed nipple is out. In fact this is where I started, planning to get the piston moving to pop it out so I could check it, thinking it might be seized. I have got the pressure switch housing off and all the brake tubes. So the next job will be to check and clean them, reassemble and have another go. However I plan to see if I can get fluid simply to come through the brake line before it's screwed into the caliper because as yet I have not had even a dribble come through the line. Something along those lines anyway.
