While tinkering with electrics , I noticed the attached (picture and part no attached) - what is it as nothing appears fixed to it or has a bit dropped off?

Sorry to return to this thread but I've now completed spraying the tank with Halfords petrol resistant lacquer, taking on board earlier comments ! But I've been hearing /reading about cutting back and polishing after lacquer application . Is this necessary or not to be done with this type of lacquer? - the finish looks quite good and I'm quite pleased for a rattle can job! The base coat was a metallic blue, the more I read the more confused I become!

I would like to replace the trip reset rubber grommet, anyone know of anyone who makes them or an off the shelf (sic) item. It's split and coming out of the housing.

I've fitted some café racer bars/ Laverda type to the 400/4 I'm very slowly turning into a café racer but a thought has just struck me that the master cylinder when / if fitted as is would be at quite an angle and could possibly not have enough brake fluid in it if leaning over too far causing an air lock in the system.
Which prompts a couple of questions:-
Has anyone done this without modifying the master cylinder?
Am I worrying unnecessarily?
Are there special master cylinders for such a set up?
Thanks in anticipation.

I bought a set of these recently from M & P, supposedly for my 400/4 , well that's what the remittance advice note/box and part invoice say. However it's only recently I've had time to fit them and my 14 days to return is up, baring the fact that all the paperwork etc is correct and maybe the wrong bits were in the correctly labelled box, I wonder if I'm doing something wrong and I do have the right bits. No matter how I try I can't get them to fit, do I need extra brackets? I've attached some photos of the bits assembled in their respective brackets and the frame left and right side if anyone could educate me where they should fit, if i use the former footrest mount no other holes line up with frame bolts etc ,I'd be grateful or have i bought another duff deal! Needless to say the so called "fitting instructions" were the one piece of paper.  Oops it appears my pc rotated the last 2 pics incorrectly.

At the risk of upsetting the purists I'm making my rebuild into a café racer ish type project . I've fitted jota bars from TEC parts and they appear good quality HOWEVER the original 400/4 switches and associated wiring go through the handlebars and the jota bars are solid ..hmm! I cant seem to find alternative switches especially for the push/pull throttle mechanism so the only conclusion appears to be drill a hole in the side/bottom of the switch as fits, disassemble the wiring (previous threads on switches duly noted!) and run the wires on the surface somehow once exiting the switch - unless of course anyone knows better!. It's too late to change my mind as other mods have been already done so don't say don't do it! I know the hole will risk water getting in but perhaps a carefully applied sealant might do the job.

Anybody used The Ferret for rewiring- have heard he's good but very busy! I want to up rate lights especially and it's a café custom too. Do I get the various components or should I upgrade to more modern systems, I'm not worried/fussed about electronic ignition though! There is no way I could do it myself. I have various old components but unsure as to how to check them, I have bought new coils and a loom though. It all seems a bit daunting 😒

i'm about to fit the coils to my rebuild but there is something amiss. the original parts listing shows the coils as discontinued so i ordered the after market coils (part no 30501-300-003P) some while ago, now is the time to fit them but there is a problem. the original brackets that fit the coils to the frame have a 5 mm tapped thread hole which the original coils fixed to via a screw. the after market coil will fit the gap in the bracket but the fixing hole is 6 mm diameter with a 6 mm bolt which wont fit the original fixing bracket - i'm assuming I just drill out the old bracket and retap a thread, also the collar when offered up gives the appearance that there will be insufficient thread for the spring washer and bolt. Any ideas or am i barking up the wrong tree!

I'm about to reassemble and install the new clutch. Any tips? I've seen mention of clutch tool on DS parts list, can it be done without it or is it worth the investment to save time and skinned knuckles? Also what does " sprag" the clutch mean? Or is there a historic link?Cheers🙂

I need the grommet for the top of the left hand crankcase cover,I can't find a part number- is it easy to make one or does anyone know who makes them or how. Ideally also need the one that goes around feeds from stator and field coil also.

I'm nearly at the point of putting the engine in the frame. I've watched a you-tube video that shows laying the engine on it's side on the ground and laying the frame over and easy peasy it's in! Has anyone done this with success or is it a spoof. I don't see how you'd get the engine frame bolts in etc. Apart from the obvious way is there another way I've put my son and son-in-law on standby to provide a bit of muscle as it's pigging heavy!

What is the correct length ,centre to centre for the rear shocks on the 400/4? David Silver patterns come in at 315mm,those I have are 320 centres and various other manufacturers go up to 345 mm and listed as for a CB 400/4.

While fitting new carb balancing screws, well that's what I think they are, 1 of the little beggars is just spinning and not tightening. Thread is good on screw , described as 5 x 6mm pan screw. I'm tempted to blank it off but would negate balancing carbs or that one later! Any ideas I'm thinking another helicoil required 😒 Photos attached to show location.

Aaargh just having spent time adjusting points/timing etc set off for ride and didn't make back gate. No clutch action, cable intact and in correct slots either end but on removing clutch adjustment cover the spring is fully extended and won't return 😒 any ideas . I've attached a photo to illustrate, I fear clutch gone somewhere inside.

While changing a throttle cable I noticed the horn is mounted on the near side as opposed to the correct. Simples eh just swap it over... nope it fouls on the number 3 ht lead and no matter what it will not fit. So returned to original/wrong position. It still works but it means that the loom support that should be there isn't but hasn't been for some time so no matter. Question is the horn is about 100mm in diameter is it the right size horn or a replacement which is bigger hence why it's mounted the other side. Over to you!
