First thing, I would inspect the R/R connector and the wires going to it. The 3yellow wires come from the stator. If you follow those wires you will come to the bullet connectors, make sure they look good and are connected securely. check the ground connections one should be on the engine case the other next to the battery on the left aft side, goes from the battery to the chassis.
If all is well heres is what you can do. Have a good charged battery, remove the seat so you can access the battery. Start the bike and check the voltage at the battery with a multimeter. With the RPMS up to about 3000 you should have 13-14 VDC maybe a bit higher. If the voltage is 15 or higher you more then likely have a bad R/R. If the voltage is about 12 and seems to drop slowly then you need to check the stator.
Theres 2 things you can do to check the stator. 1) Check continuity of the stator wires to ground. 2) Check the continuity of the stator wires to each other.
1). Remove the R/R connector check each of the yellow wires to ground. You should not have any continuity at all.
2). To check each wire together, mentally number the wires 1,2 &3. Check continuity from 1-2, 1-3, 2-3 you should have 1-3 Ohms of resistance.
If the reading are not correct I would disconnect the yellow wires at the bullet connectors and check them there, more then likely you will have the same readings (this will eliminate a section of the wire harness to be the fault).
If you have to replace the stator you DO NOT have to do the engine case mod. However the engine would have to be removed from the bike or some people tilt the motor enough to get the cover off. When I had to replace my stator I removed the engine completely.
