Hows it going? If you have a multimeter you need to remove the seat and with the bike running at 3000-4000 RPM's measure the voltage across the battery. You should have close to 14 VDC maybe a bit higher. Anything over 15 VDC you may have a bad R/R. If you have batterty voltage 12VDC and you can see this value decrease as the bike is running then you have a charging system problem.
If thats the case you need to inspect the wires going to the R/R and also check the grounds, One on the engine case and one next to the Neg terminal of the battery. in fact it goes to the neg terminal of the battery.
The Second step would be to do continuty checks of the stator. The 3 yellow wires on the R/R plug are your stator wires. Unplug the R/R and check each one to ground. You should have NO continuity. Then check each wire to another. Mentally lable them 1,2 &3. Check 1-2, 1-3, & 2-3. you should have 1-2 OHMS resistance for these readings.
Let us know what you come up with.
