CB400F Carb overhaul
Bryanj:
Must admit to never having removed the choke plate screws, for the simple reason that i didn't fancy having to refix them!! As to airflow these carbs are, in my opinion, such an old and agricultural design that a disturbance of airflow was not even considered when thewy were built.
i have in fact been on the motorway with a 500 when the leggings knocked the choke lever on and yes it does slow down quick but not as bad as an engine seize!!
Lobo:
Thanks K2/6, Bryan,
Job done, will be months before I can verify all upto scratch as engine about to go for recon and thence (with summer leave) will rebuild the bike.
Still totally 'befuddled' as to why the darned set-up has to be so complicated - from my untrained eye it all appears to offer nothing over the simpler 750/K2 onwards carbs.
Below the finished product - painted & lacquered in petrol resistant finish. Would have dearly liked them vapour-blasted & plated etc.... but living here in a third world country and re-conditioning bits you've dragged back in yer suitcase has limitations! Vapour-blasting etc may arrive here in oh...50 yrs. If the finish doesn't wear well it only has to last a couple of years to my perm return & then will do it all over again....ugh.
Cheers & thanks to all for the various inputs - the balancer SS tie pieces await me in Hampshire..I hope.

Just make sure you put them on the right way up :).

Thanks OddJob, will sleep a little better on the choke flap screws comment. If you're a glutton for punishment, sure, spend hours cleaning, spraying, lacquering....or simply bung the bits in a box & take 'em somewhere to be zinc plated whatever, at a reasonable cost! (I'm assuming you live somewhere that can offer such a service). Bonus is they'll come back original looking.
Or, how's about.....http://www.gaterosplating.co.uk/Zinc-Plating-kit.php.
Gawd I wish I were back...(this stuff not allowed an aeroplane)
Yup, as in my last sentence, (and not knowing their correct name) those 'links' await me in Hampshire and will be fitted once I get home this summer.
Cheers...
Lynx:
Does anyone know where to get, or what to use for those felt 'washers' in the carbs where the linkage shafts go in? Mine are even broken or lost :-\.
Cheers
