Unhappy Honda TRX 400EX - Doesn't want to start

Hi everybody,

I made repairs to the engine of my TRX 400ex 2007, I changed the piston and valves. Small engine job, because he no longer start. After all changed, I tried it and he start, but do a strange noise. I re-adjusted the valves and tried to start it. Without success.
While I adjust the valves before it will not start.
I thought it was the coil, so I changed it.
There are current before reached the coil. When I plug the coil, there is no longer current. The motor rotates but does not start.
What do you think it can be?
Help me please.

My first guess is you didn't get the cam timed right and bent the valves - check the compression - with the throttle held wide open, you should get something over 120psi within 3 to 5 compression strokes
