You can set timing with a timing light or by setting statically.

Remove the crankcase timing plug and expose the timing hole.
Install a clear plastic timing hole plug to prevent oil splash.
Connect the positive terminal of an inductive timing light to the positive battery terminal of the motorcycle.
Connect the negative terminal of the timing light to the negative terminal of the battery.
Connect the inductive pickup probe of the timing light to the front cylinder spark plug wire.
Start the engine, and run it at idle. Point the timing light into the timing inspection hole.
If the ignition is properly timed, the timing bar will align with the circular timing reference mark.
The reference mark on a correctly timed Evo will appear as a vertical bar through the center of the circle.
Remove the timing cover from the right side of the motor.

Recheck the timing marks with the timing light.
