I have managed to get hold of a MPH speedo for my bike. The only problem is that mine has done 25,000 miles and the new unit is reading 70,000. I have had a look at it but the number cluster has been peened in with a chisel and I fear breaking it if I try to remove it. So it looks as if my bike is going to gain 45k in a weekend.
Any thoughts?
Nick

I'm not sure where you stand legally on altering the recorded miles; I presume the crime would be misrepresenting the age, condition etc. My first NTV had a KpH speedo (grey import from Finland I subsequently discovered). I bought a MpH one and have kept the KpH to show the reading when I bought the bike (nearly 95k Km or say 60k miles). I did look at the arrangment and would be certain it's not too difficult to open the frame with the number cluster in, but it would be obvious to anyone who looked that it had been tampered with. My advice would be to put the MpH speedo on and keep the KpH to show any prospective purchaser. Any idle passerby would see your bike, perhaps notice 70k miles and think "wow that's in good condition". I would also take a photo with both clocks and a front page from a daily newspaper. When you sold the bike at least you could explain what the true mileage is and have some "evidence" to support your explanation. Have you got 25k Km recorded, or 40k Km (which would be 25k miles)?

*ahem* I know it's not legal, but you could run the clock till it shows about the right milage....(with a electric screwdriver or something). I'm no expert, but I asume that once the counter hits 0 again it doesn't keep score of it being over 100.000, right? And ofcourse, take a pic to show that you weren't trying to scam anyone. ow....and remember to be nice to the screwdriver....it will have done 55000 miles by the end of it

An interesting suggestion, and one that went through my mind while out today (using a drill to wind the clock forwards) I then thought, if you could simulate 200 miles per hour and the speedo can tolerate it, it will take 5 hours to advance 1,000 miles and therefore require 150 hours to get to zero.
If your drill is rated at say 600W and 1KwH costs £0.11 (the cheaper of the two rates on our last bill), it will cost £0.066 for every hour you run it, therefore £9.90 in total.
If you can get it all to work at 1,000 mph, it would only take 30 hours, but I'm guessing the bits inside the speedo would not tolerate that amount of stress. At £1.98 it's cheaper on the electricity bill though!

I only mention this because you are undoubtedly honest types:- The numbers on the mileometer are ratchet driven- only the last one is driven by a worm and the rest just 'click' when nudged by the next one on the right. If you can gain access to the numbers, front or back, you can spin the wheels with something pointyand select the numbers you want. However, if you leave telltale marks on the numbers when you 'ferkle' them you will make some people very suspicious. Maybe best to leave alone. Let's face it, Aunties are so old now that you aint going to lose a load of dosh when you sell- if they go nicely they are worth so much. Look at it another way- a high mileage is a badge of honour for some people. Have fun. Bill

Elegantly and delicatly put Bill, well done! I have never tampered with an odometer (honestly your honour!) but they don't sound as tamper proof as I had imagined.
I'm now curious about digital odometers, surely they must be easy for a hacker to hack?

Yup. Right cable and software, and away you go.

I distincly remember an episode of Eastenders years back, when Phil Mitchell was clocking a car using a drill on the speedo - having seen McF's analysis, I'm beginning to wonder if the programme was entirely realistic in this regard. Blatently misleading the public I call it. More sackings at the Beeb required.

Well done STB, I noted my own "coming of age" the other day.
I'm not so sure that it was advisable to admit so publicly you are a "stenders" watcher, but you did say it was "years back".
I am proud to say that I have never watched an episode. I have to concede, that I'm a sad git who rarely watches TV, so that includes "Corry"; "Emmers"; Neighbours et al.

Eastenders long off my radar - too much shouting. I watch Corrie once a week or so with Mrs Buffs, I like the camp humour, but wouldn't care if I never saw it again. Telly is a terrible thief of time. But then so's the t'interweb. If only I had a nice warm garage to play in...

Thank you all for the advice. In response to MCF neither, my bike is fitted with a mechanical motrax converter, which reduces the rate of the speedo drive by 1.6. Therefore when my clock reads 30KPH the bike is doing 30 MPH and hence my problem, the range of speeds that I am using are crammed into the bottom third of the dial.
Bill, I did try to ease the digits over as I have good access to the back of them, having taken the dial out and they seem to meet resistance. Not wishing to wreck it I haven't forced the issue. Looks like my bike is going to jump up to 70K.
I take the point about not loosing value, as I ONLY PAID £600 FOR THE Bike.
On another note the CB500 Speedo internals look very similar.
cheers all
Nick
