There have beena few threads on overdrive conversions and one of the issues that came up was recalibration of Speedos. Coincidentally I;ve been disposing
of a number of Triumph 2000 NOS speedos and was contacted by a guy who said he was interested in a acquiring several. I got into correspondence with him,
turns out he's a professional speedo restorer and recalibrator - web site here www.jdo1.com. his name is John Ostick and he seems a nice guy with prices
not out of this world. Having said that I've never had a speedo recalibrated, restored or otherwise messed about with and I have no experience of John's
work so I'm just putting this up here for information - if anyone does put some work his way please come back and give an opinion on price, quality and
value for money

I had my speedo recalibrated by John Ostick recently, following a change of diff ratio. He was very helpful on the phone and said he had been
calibrating speedos etc for decades. He described in detail how to acquire the data for the calibration parameters (and what not to do). I sent it off
and it was returned in less than a week (even during the recent postal strike in my area). The speedo now is fine - the rev counter/speedo comparison
is correct. The rev counter (actually in my car it is a tachometer) was calibrated by me previously.
The cost was £27.50 plus £10.00 because the speedo had to be altered sufficiently to accomodate the new diff ratio (3.89
replaced with 3.63). To sum up I experienced good & helpful service. Incidentally, he marks the new calibration factor on the speedo case for
future reference.
For info - standard speedo calibration is set at 1000 turns of the cable per mile.
