In the nose cone is an ignition module, it has on the back two magnetic pickups, You can remove the cover, mark the timing and then pull it straight out be careful to not really twist it and pop off one of the magnets, make sure they are both on there, (I have seen one broken off bike wont fire)
Also check the plugs to see if they are getting full spark, you can pull them and rest on the head have friend turn it over and see if it sparks or get a spark testing light to plug into the plug wire.
Check wires running from the nose cone up to the coil, make sure you have them in the right place three posts, on that I think. You can download instructions on the ignition from
Crane go to the motorcycle section the motor is of course an EVO. I'm guessing a HI-4 ignition.
Check for good grounds on the battery too.
If it's a big inch 100 then you can wire a relay (Crane sells them but you can get a 4 pole relay from a car store) and wire it to the starter, coil and battery then direct to frame ground) this will let more power get to the coil when starting.
