Report "odometer on my 2000 V11 sport indicates speed ( 17%) and odometer ( 22% ) short of actual - I have done field tests and measurement and can only conclude that the Speedo gearing ( pick-up is from the drive shaft ) is incorrect there are two part numbers 2001 -- Gu04762500 2003 and later -- Gu 01762560 these parts "look" interchangeable ( i have not felt them ) is there a different ratio between thes sets - what is it for each the speedo has been verified as accurate"
