2000 yamaha r6 wire diagram

Check the battery.Is it charged?Also does the neutral light go on?
If not check the neutral switch.
The neutral switch is behind the engine case near the rear shock and has one wire. Make sure the bike is in neutral or on stands. Remove the one wire and put it to earth/chassis/ground (somewhere metal on the bike). The neutral light should come on and you should be able to start the bike if that was the problem.

if the wiring diagram where the same it will work.
