Hi all ,
in the process of finishing cr750 replica,looking for rough size of cb400f speedometer,thinking of using instead of cb750 clock as it's to big for the space I have.
Thanks
-
The CB400f speedo has a four inches diameter at it's widest. I just gave away my spare so I can't help there. But if you decide it's what you want you can get very good replica's on the David Silver Spares site, just assuming they will still be accurate on your bike. Here are my own:

Hi,
Thanks for reply,I did not get any clocks with bike so have nothing to cross reference with,looking at pictures I thought the 400 clocks were smaller than the 750,I am looking to purchase some but was wanting to stay with original honda look

Depends on size of wheel, if its 19 inch you need a UK 500 or an early 450 twin one. The 400 was a different ratio
-
Hi
19inch wheel,do you no what ratio I will need?
Thanks
-
Use one off a 500-4, that had a 19” front wheel
-
I thought all of the Jap bikes from the 70s had the same ratio on the speedos , 2240 rpm on the speedo input shaft for 60 mph. Any gearing for wheel size is done at the drive housing on the axle.
Tacho's are a little different between bikes.
Honda 7:1 , newer VFR/CBR 4:1
Yamaha 5:1
Kawasakii 5:1

Smiths speedometer clocks had the Wey speed printed on the dial face back in the 1960's.

I've been trying to figure out what Wey speed is over my morning coffee. ;) Mixed results on google. ::)

It's a term I heard back in the 1960s when my Moggie 1000 had a silver faced speedometer and I replaced it with a black one from a Mini. I assumed it was an engineering term iirc it was a four figure number that represented a number of rotations over a fixed distance. Of course the term might have been wrongly remembered by me, it appears TPM might be the correct term.

I see Ted. I've learnt what a Moggie 1000 is now too. Still India's national car isn't it not?
-
Nope, that is the Oxford i think, bit bigger
-
A Morris Oxford is substantially bigger. My Dad had both a Moggie and an Oxford back in the day. I was driving the Oxford when it got ripped into 2 parts by a drunk driver doing over 100mph in a Daimler Sovereign, ripped the engine bay right off the car, left me with my feet dangling in the air as the firewall went with the engine. Broke my neck at the same time, put my head through the roof (hence the neck) and put my shoulder so hard into the door it burst the lock. Closest I've come to dying, no idea how I walked away from that accident. It was 3 weeks before they spotted the broken neck, still hurts in cold weather and if I wear a helmet too long.

Well wow! The things I learn on the SOHC forums! ;D
-
My dad has a Moggy Thou' when I was a kid. Really felt like you were tearing up the tarmac if it got up to 45mph.
-
The Indian one is called a Hindustan Ambassador and is a Morris Oxford Mk111.
Thank you mr google

Aside from the Moggie I owned back in 1967, when I joined the Police in 1971 Derbyshire Pandas were the Pollce Spec Moggie 1000.
The Police Special version was not tuned up in any way, it did however have Servo assisted Drum rakes all round with a high output Alternator due to the power sapping VHF Radios. If you eft the radio on without the engine running it would drain the battery in under an hour,

Bloody Hell!!😳 surely won’t get closer than that at meeting your maker!😳

Very true Johnny. What's surreal about it is that I've been through the junction hundreds of time but never from the side, always along the main road. When the lights changed I had no idea of the sequence, do I go first, do the opposite side go first etc, so I delayed a fraction of a second, the other side stayed stationary, oh I thought, I go first, I set off and as soon as I did the other side moved, bummer I thought as I was turning right, so I took my foot off the accelerator and that's what saved my life, 2 feet further and I would be dead.
The worst thing about the accident was I'd asked my Dad if I could borrow his car that night, he said no he had an early start on the trains the next day, he went to bed about 7 o'clock due to that, don't worry said my mum, as soon as he's asleep I'll get the keys, he'll never know. So when I got a taxi home that night I had to wake my Dad and tell him I'd been in an accident, is it bad he said, no, I don't think so, I said. We got a taxi back up to the accident and one half of the car was on some waste ground on one side and the road and the other end was on our side, I had no recollection of seeing it like that before. The car was my Dads pride and joy and I don't think he ever forgave me, we went over to the back end and the roof had a perfect shape of my head in it, the metal had just started to split open on the crown, as soon as I saw it my neck started hurting, weird.

Just when I thought it couldn’t get worse! I’m sure your dad would rather you were alive and well than have his pride and joy. Amazing how a split second decision can be a matter of alive or dead!😱 I had a head on collision with an escort van, I had a Jaguar xj6, the engine of the escort van was pushed back 2 feet the engine of the Jaguar 2 inches, according to the accident report. I was completely at fault pulling out from filling station into oncoming traffic after being awake for 36 hours. One of the policemen who attended the accident bought the xj6 from me for stock car racing. 😂 Amazingly no one seriously injured, although they definately came off worse.

My sister had a head on with a 5 series BMW on her NSR250, bounced off it and landed in a ditch. Had several operations over a 5 year period to put her pelvis and wrist back together. Still in constant pain after 20 years. The idiot BMW driver pulled out to pass a dawdler on a narrow back road without looking. :(
