Hello again,
I've just acquired a used reg/rec from America which was taken off a 1970s CB400F, but it only has the three yellow wires in one plug, with the black/green/red-white leads in a separate plug, but no white wire. Any ideas anyone? The sellers say that the unit was taken from a working bike.
Cheers, MikeJ

Well, I don't have any plates at the moment so I might as well make some, and alloy's a bit lighter,

Hello All,
does anyone have drawings for alloy engine plates for the CB400F. I'm too cheap to buy a commercial set (call me Arkwright) so am trying to do a set myself,

Hello,
many thanks for the info. but is there a standard later Reg/Rec that will fit and cost a bit less?

Hello, thanks for the reply. I notice that some reg/recs have one yellow lead rather than three , so which type would be suitable?

Hello,
the seventies CB400F uses a separate rectifier and regulator, according to the wiring diagram. Is it possible to use a modern 12V one piece regulator-rectifier instead, and what wiring changes would be necessary? Any help gratefully received!
Cheers, MikeJ

Hello,
I've just bought an overbored 450cc CB400F engine and was going to have a set of carbs bored out to 22m and rejet. however, the carbs, which are standard as far as I know, have a 22mm bore at the engine end but are choked to a smaller vertical oval cross section at the slides. Is this normal for the CB400 and is it possible to increase the bore size on these carbs (I don't have an oval drill!)?
Cheers, Mike J

Hello there, thanks for checking- I don't know if the yokes I have are for a CB550F maybe? I don't know if they're different. Anyway, I've got a set of 750 yokes which will fit with a bit of finagling,
Cheers, MikeJ

Hello again,
weirdly, the CB550 yokes put the fork legs closer together than the 400F, so I wouldn't be able to use the wheel I want. Does anyone know if a set of CB750 yokes would fit, and what the leg spacing and diameter dimensions would be?
Cheers, MikeJ

Hello again,
can anyone please tell me if the later 80s-90s exhaust system will fit on the earlier 70s CB400F? Just the exhaust pipes, not the silencer. I'm thinking of fitting a Supertrapp silencer to whatever is fitted eventually,
Cheers, MikeJ

O.K., thanks Noriron, I'll keep an eye out for that when the time comes,
Cheers, MikeJ
