Ok Guys, Both Myself and Kiwi John have D-Trackers. Now We are fitting KLX Wheels for Off Road. The Question is With the 21 inch Front Wheel fitted the D-Tracker Speedo reads 8 kmh Slower than Normal? Kawasaki Claim to have the Same part Numbers for both KLX & D-Tracker for the the Speedo and the Electronic Drive Unit fitted to the Wheel??? One of these is obviously Not the Same on Both Bikes so how do I find out which? The Speedos have Different Back Light colours so I am Guessing it is this that is different as the Magnetic Drive looks identical? Any Theories out there Gentleman??? Thanks.
