I thought it was worth expanding what I've been saying about speed of late. I'm assuming that as you can get add-on devices to measure car speed these must be considered an accurate way to measure progress. So with changes to my gearbox I'm now doing approximately 54mph when the speedo reads 50. I covered 86 miles when the odometer read about 80. So I reckon the car reads about 8% under on both counts. (Mathematicians please correct this). I'm now wondering how accurate the speedo was in the original and then the standard 650 gearbox incarnations? Maybe I've done more miles than I thought. I'll need to adjust things in future and I suppose it will change again with slightly wider and different profile tyres? My calculations are important...... we're talking money here.....my company mileage claim. Also worth remembering in respect of speed cameras.[emoji849]
Does anyone else know how closely their speedo compares with reality?
