I called
Electrosport Gauges today, they are the US importers of Acewell clocks and they told me that there isn't a speedo cable for the SV650 and one wouldn't be available for a few months!! Odd eh? So I called back and asked if the univeral pick up mount with magnets on the front wheel would work and he said that on the SV it caused a problem. Yeah okay right, so he is trying to ask someone else and then call me back.

So my question is to you that have Acewell Clocks (26xx, 29xx, 37xx, and 39xx): what cable are you using to run the speedo and is it accurate?? These things are made to fit on ATVs, scooters and bikes so I can't imagine why the
SV and it's front wheel would cause any problems with accurate speed measuring. Even the specs of the 3700/3900 say it has adjustable wheel circumference setting from 1-3999mm.
HELP!!!!!!
