I have an 04 yfz 450, and I recently seized the crank. So I tore apart the motor to replace it. Everything inside looked great. While I had the motor apart I decided to replace the piston with a Wiseco 13:1 high compression piston. I got everything back together and went to start it and it seems like there is not enough power to get it going. I put in a brand new fully charged battery and still, no. We push started it and it runs awesome, but I don't want to have to push start it on the track. Any suggestions?

 

Put a kick start on it.

Fuse blown?

Does the starter move at all?
