Speedo Correction

[YellaBelly]

Right, I've been putting this off for long enough!

I really need to sort out my Speedo inaccuracy. It over-reads by way too much and I want to try and sort it before the driving season gets going proper.

It is a Type 9 5-speed box mechanical drive via a 90deg adapter to the speedo. I know there are different ways of sorting it, but what is the collective view on the best, and cheapest!, method? I know the uber cheap route is to make a new face for it, but I don't want to do that if I can help it as it will just end up looking tacky

Any ideas chaps?

You could aways put bigger or smaller tyres on 

dont they just change the driven gear coming out the box

If I had cash you had mate I would!

But yes, I did find an article somewhere on changing the driven gears or something, no piccies etc. though so more digging required methinks!

Not sure whether it will change it enough though, I need to do more homework.

Electronic speedo? Cheap pushbike one might do if money is tight.
