4-2 MACHINE TUNING
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 in the motorcycle shipping crate and connect it to the mode
select coupler. 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).
NOTE:
The changeover is executed immediately after the engine has
been started.
• Select White short wire (map for slightly leaner mixture) when:
1) Raining
2) In highly humidity
• Select Gray short wire (map for slightly richer mixture) when:
1) In low humidity
2) At continuous high speed
NOTE:
The above information is provided only as a guide. To determine
the setting, make sure to check also for drivability and spark
plug firing end condition.
