Green or blue faced clocks

[sye]

Hello all, I recently purchased a 1972 500 for F1, frame and engine number both start with 2010? One clock has a blue face and the other green, which was correct for this model please?

These are new clocks, not refaced. One photo shows them as the eye sees the faces (very similar colours). The other photo is with a flash which shows them as blue and green. [ Guests cannot view attachments ]

They fade in the sun over time, the tacho fades more than the speedo. These are 18,000 mile faded but original faces. [ Guests cannot view attachments ]

Sorry, got side-tracked there but what I was trying to show is that the faces were never the same colour in the first place to look at in some lights. Hope this helps.

All UK 500s came with clocks as shown by Julie. Some with/without the red 70 line I think. Are they the 80mm dia clocks as Julie shows or has someone fitted the later 95mm dia clocks?

Thanks Julie, that's very helpful. The speedo clearly has a blue face but the tacho has a green one. The mileage is verified with every MOT until 2003 when it was taken off the road, so I'm puzzled as to why it would be blue?

Seabeowner, I'll measure later and verify, thanks.

Looks to be the correct 80mm.
Some CB/CL450 clocks were the same 130MPH, 80mm. What colour were they?..

So you have every MOT from it's first in 1975, (Im assuming its a 72 reg) until 2003 ?.

Actually no, I was mistaken.
1st: 30th July 1979 showing 7508 miles
Last: 27th August 2002 showing 8729 miles

Not used since 2003. Go figure? It must have been in front of the telly and not ridden much.

That's an average of 53 miles per year, ha ha. Maybe it's 26.5 miles to the MOT station or it's a load of bolleau. Time will tell when the engine is stripped and inspected.

Sounds unlikely that it's genuine but some people just do incredibly low mileage but it is very very rare. Most owners that bought a CB Honda in 1972 would have done the 7508 miles by the following weekend after delivery  We know someone who does 2 miles a year on his old BMW bike, a mile each way to be MOT'd.

A clue here might be the dial face screws, early gauges had screws with a smaller head than later ones. Presumably because the face had a tendency to work loose. It looks like the speedometer has the screws with the larger head and as this is an early machine it might be that the gauge has been replaced.  Just a thought!

I noticed that too Peter as I was just comparing the photos of the faces with the photos I put on.

Here is an image of a CB500f dial face that's become loose on the small screws. A spot of thread lock in the screw holes is a good plan but not on the screws as any thread lock will getting on the face will take the print off. [ Guests cannot view attachments ]
