Hi I have a 2010 yz450 that i had torn down to have the frame welded. The only thing left on the frame was the foot peg brackets. Now that it is back together it wont start and doesn't have any spark. I have gone through most of the electrical conections, and tested their resistance which were all within spec. I'm at a loss for what to do now. Any help is apreciated.

It started fine before i tore it down.

Took all of the electrical off, and looked over everything then put it back on, and it fired up on the first kick. I guess it was just a loose conection somewhere. Thanks for the advise.
