hmmm can't adjust the primary - then, as has been said, a real need to adjust/sync the carbs and this seems to be the noise i can hear rather then the cam chain

forgot to mention, i have run it with the air pilot at 2 turns out as a rough setup before i think about the sync and it seems to run best (without sync) at 2 3/4 turns out - which i think is a bit too far out (even with spring loading they could undo) - so may have to try 2 1/2 out and stick with it for the time being.

it ticks over at 1400 ish (at 1200 the primary rattle/lash is just too much for me to endure) but the rev counter clearly shows a very small bit of movement up and down and the bike has an annoying habbit of settling down at a lower rev level after a few moments - hopefully the sync will stop these little niggles

at last carbs seem to be 'ok' so primary and cam chains make less noise than they used to, cleaned most of the elec. terminals, new cables and i'm almost there.

still need to change the cut down front mudguard and front brake line but they can wait.  i will put a couple of pics up in the near future.  bring on the sun!

pics make it look a bit better than it is - you cannot see the staining on the chrome - but i'm not into making a bike look like its just off the production line just an honest 40 year old reasonably looked after.

Looks better than my chrome, but they are what they are, old bikes. As long as it puts a smile on your face that's all that matters. Looking forward to getting my V5 sometime.  :D

now its (almost) just a matter of getting it insured and trying it out - hopefully the riding position won't give me cramp (i'm more used to cruisers)

on insurance, i have found a reasonable one for £85 (fully comp, limited miles, 10years ncb, low excess) via gocompare but people like say swinton don't insure over 30years old and p james want about £140 - my existing insurance (bennetts) have some stupid requirement that says if you are within 500yards of your home and say bike is garaged (like most are) but wheel it out onto the drive so get your gear on/clean it then it is only partially insured and you have to pay part of the cost if it is nicked!

any suggested companies with a good price??

I use Swinton for my CB400/4 and some other 40+ year old bikes on individual, not a multi policy, but you need to phone them as it says on the compare sites, they dont insure over 30 years old but they do.
I pay £63, fully comp and that policy also covers me 3rd party, to ride any unlimited cc bike as long as its not owned be me and insured. I know by discussions on here before, i have the cheapest premium in the UK by the sounds of it. It's due to where i live, being a retired Nurse, single, getting old, 40 years full bike license etc etc. Worth giving them a call though.
Edit...I lied, It's £60.37 Carol Nash are also the same price.

hi, thanks.

i tried ringing swinton but it seems that for whatever reason no quotes were available.  anyway bikesure came throu at £68.95 with a few requirements - like not insured as soon as you take it out of the garage  >:( - until you are going for a ride but at least its insured.

You're machine looks really sharp.
Mine was originally yellow.  Sprayed black at some point in its life by a PO.
May go back to yellow in due time.

the story so far.

as i said earlier the insurance is done and, notwithstanding whatever has been said about dvla, the road tax was ready on the 1st and free so must have also been recorded as historic, so i took it out for a 'shakedown'.

a bit of fiddling with the carbs and it seems to run ok engine wise (brakes are now't to write home about but may need bedding in) but the gear selection is not good - clutch drag.

taking the plate off i find the actuation lever 'hole' that bolts to the shaft is somethat oval so the bit where the cable nipple fits into is touching the inside top of the case - had to send to the usa for a used replacement which hopefully will fit, and..

whoever owned this bike before also had the wrong clutch cable adjuster - its seems to be m10 x 44 but this is m8 so they just added a couple of nuts to stop it going into the case,

anyone know where i can find the correct adjuster and nut - m10 x 44,  22818-354-000 and 94001-10000-os 10mm hex??? or just continue with the nuts for the time being?

being of a certain age+, i can't give you a direct link. I.T.wise b t of a dinosaur.  if you go to Ebay and type  in "Honda cb400  four stainless steel" and scroll down  you will find the clutch cable adjuster you're looking for.  £19 from mybikebits.  hope this helps
