I saw from your other thread that you have already tested the starter relay, and it was good. You should be able to eliminate the relay itself as the source of your problem.
That blue/white wire that feeds the starter relay originates at the multi-function relay unit (9 pin), located under the left side scoop.
The Clymer manual outlines how to test for continuity of this unit, but to simplify testing-
-the unit recieves power from the black/red wire, coming from the downstream side of the engine stop switch. So with the ignition on, and the stop switch in the run position, there should be battery voltage going into the black/red wire at the relay unit.
The starter switch is also channeled thru this same relay unit, by way of another blue/white wire. So with the ignition on, this wire as well should have battery voltage at the relay, when the starter switch is pressed on. Doing this should supply power to the blue/white wire going to the starter relay, (providing the relay unit is working properly), and this should fire your bike up.
Let us know how you do.
Cheers!
