I've looked at the normal parts outlets and nobody seems to supply one that small. Can any of you suggest a supplier for this part please? Keeping the Bee Buzzin'

There also is a mini reduction gearbox the size of your fist that goes inline on the speedo cable to fine tune adjust the speed also. I have one but no pic at the moment. live every 24 hour block of time like it's your last day on earth

I went with a heads up display GPS speedometer Gtop HG100. There are a lot of GPS speedometers around to choose from. What's cool is you can change tires, gears, whatever, it doesn't care.

I am looking at the same situation but want to make sure the speedo gear is as correct as possible. These things have gotten expensive. I remember when they were 1/2 the prices they are today.

Free for basic, couple of bucks for upgrade. Perfect for checking out accuracy of speedo and odometer. The more teeth you have on your 'driven' gear on speedo cable, the slower your speedo reads compared to your actual true speed. The drive gear is the one on trans tail shaft. Contrary to op's thoughts, I believe you need a driven gear with fewer teeth, not more. When does the ground war begin? 8460267-image.jpg (94 downloads) Last edited by Sxrxrnr; 03/14/15 11:54 PM.
