i asked before and i had a reply to try ronaryes.com i cannot get this site to come up. i called my local suzuki shop and they said there was no such thing as a "yellow box" to calibrate when the gears are changed (yet they have not been able to answer any question that this forum has been able to answer). anyway, just wondering where i can pick up one of these yellow things. id like to get the 01 speedo back to the way it should be. thanks all.
