SELECTION OF ECM TUNING MAP

In the ECM of this model, there are three different maps pro-
vided, a standard map and two modified maps (injection map for
slightly leaner mixture and that for slightly richer mixture).
Select the appropriate short wire among those that come sup-
plied with the motorcycle and connect it to the mode select cou-
pler. This can change the ECM setting to the modified map
(either injection map for slightly leaner mixture or that for slightly
richer mixture depending on the selected shunt wire).
