Speedo not Acurate
I changed the faces on my GXE to the white SE face and also changed the needles except my speedometer isnt right any more its says i am going faster than i am. Is there anyway to resycronize the speedo, or set in back to zero?

Speedo Calibration, DIY:
1. Measure your actual speed: Use the speed u think is most important for u to be accurate. The only way is to use a CHECKED distance, steady speed and stop watch and calculate your speed. Its easy, but u have to be accurate. Recheck, recalculate.
2. Write down your measurement speed and what is the actual speed u just calculated
3. Take gauge off.
4. Find a way to lock the needle in the position that u measured the speed.
5. Take needle off, push it down to the position that the actual speed was.
Note: -Most often the gauge is not linear, meaning error in 30 is different form error say 70. This is why (*1) its good to select the most important speed for your calibration process.
- Wheel size change (front) also causes errors to the speedo, odo, may be corrected like this.
- When odometer error is known, it can be used as distance 'yardstick' in this speedo calibration.
- The longer your distance is, the easier it is to be accurate in your measurement. If there is an exact 5mile level strip where u can keep steady pace, good. Half a mile is ok, but needs accuracy in timing.
