I thought the speedo was reading high, today got my first quick readings with a GPS;
these may not be exact but should be close. Speedo GPS reading reading 30 20.7 40 29.6 50 39.7 I have no history on the tranny gearing, but these readings should only be affected by the R & P gears and i didn't think there were any options there. Rear tire diameter is 23.75. Not sure what the OEM size would have been. What's going on here ?? |
