There's a similar discussion on the new K1200GT forum but now nearly as in depth as this one, at least at the moment. Has anyone opened the speedometer yet? I haven't but if the speedo has as similar calibration adjuster then here's how I set my K11LT speedo bang on.
And if you think this is nuts you won't hurt my feelings.
1. New rear tire.
2. Measure the circumference of the rear tire exactly.
3. Calculate the number of revolutions that the rear tire must turn per minute for three different speeds. 20 mph, 40 mph and 60 should work.
4. Borrow or buy a strobe tachometer.
5. Stick a small piece of reflective tape exactly in the center of the rear tire tread making sure that it won't fly off.
6. Make sure the bike is secure on the center stand. It's best to have the front tire against a wall.
7. With the speedo open for adjustment fire up the engine and up shift through the gears to top gear.
8. Hold the rear wheel speed at the pre-determined rpm point and adjust the speedo to match the exact indicated speed for the tire rpm. Check each point and readjust as necessary.
I know of other methods that require a computer and other equipment to set the speedometer but this method is simple and bang on too.
Regardless of the method, good luck.
