CB750 four K0 speedometer reset

[BobDavies]

I have spent the last 4 years restoring a 1969 CB750 four. (Not sandcast) I had the clocks restored in the Netherlands but they didn’t reset the mileage to zero. This has been a painstaking ground up restoration and I’d like the mileage to reflect that. Does anyone have a contact where I might get this done. TIA.

Kent400 a member here does clock restoration. (Peter Horton)

To me that looks like trying to hide something. I prefer to keep the genuine mileage as that's part of the bikes history. Personal preference I guess. Definitely Peter Horton as recommended above.

How many speedos can a bike be fitted with over a span of 50 years Roy? Mileage should be taken tongue in cheek unless the bike clearly still has say the original tyres etc.

I also prefer to reset mine back to 0 as I can then tell at a glance how the engine should be performing etc.

As I say, personal preference.

I remember arguing with a trading standards man over i bike i knew had had 4 speedos through accidents so mileage was not true, that eventually ended up with stickers on the glass of all sales bikes to shut them up

I don't know if my odo should be considered as over reading or under reading as the original stoped working at 80k I've done about 20k since owning the bike and the replacement Speedo has 26k on it.

Exactly why I prefer to have replacements zeroed out. My first 500 has had 5 clocks, the first lasted well over 100,000 miles, then I had to fit another, so I had to mentally add the 2 together to work out its true mileage, then again when I fitted the 3rd and so on. The 500 I’m currently restoring has had at least 3 speedos, the last 2 being of the 550f type. So I know the total mileage, this time all I need to do is add whatever is currently on the clock to the total and I’ve got the correct figure. Far easier to keep check on oil changes etc.

I have always disregarded the odo on any vehicle. If it runs well and I want it I buy it.
My aprilia has it's original Speedo but the milage is wrong as in my ownership it has snapped at least 3 Speedo cables and I'm always incredibly slow at changing them.

I've always thought an hour counter like on planet machinery would make more sense. Distance is irrelevant

A lot of light aircraft have an engine hour counter (difficult to measure mileage in the air!).
Even those can eventually fail though, so you would have the same replacement counter problem.

I did one a couple of months ago but also did one a few years back.
On the recent one, Peter Horton advised me on a way of resetting without stripping the whole mechanism down and risking damage to the delicate mainspring/shaft etc. It did involve bending the metalwork back though ...but if it's good enough for guru Peter ... then it's good enough for me.

I think I  have an email from Peter about it but I don't want to pass on without his blessing or you can message him directly.

On the topic of oddometer reading / mileage there is also the factor of what type of use a vehicle has, my experience is mainly on cars.

I bought a cheap 10 year old Opel Ascona back in the early 1980's it belonged to a Turkey Farmer who used the vehicle to drive to a local Church less than three miles from his farm. The vehicle had covered just over 16,000 miles, he had it serviced by the main dealer every year.

When I changed the rocker cover due to an oil leak the valve gear was thick with sludge as was the inside of the rocker cover.
It had clearly spent half its mileage with the automatic choke on. After only 18 months of ownership it started with little end clatter and other horrible engine noises, after my additional 15k miles the engine/car was scrap.

My uncle ran a garage and back in the 70's he had two ford escorts in for work, the cars had registrations from same main dealer with numbers within 10 of each other

1 reps car, phenominal mileage in for service mot and out

2 actual little old ladies car, very low mileage, needed new engine

That’s interesting Bryan. Acquired a low mileage Mk2 Escort in the mid eighties that belonged to my wife’s grandad. He had lost his confidence to drive so gave us the car as we had sold ours to raise funds for major roof repairs. His max was about 40mph and that was on a major road on a good day. We set off on the ferry and drove to Aberdeen which is 200 plus miles, we had to keep stopping and let it cool down as it was overheating.😡 It was fine on the way back. 😂. It was a pig to start on a damp morning.
