Hello and thanks for reading, I have recently built a crf450r with a hegar jackshaft. Everything in the motor is new from piston to electronics. Stater, coil, plug, plug wire, cdi box, all brand new. I have not replaced harness due to the fact that every wire has been tested multiple times by me and my father, and every wire has continuity. Also coil is grounded directly to the motor with a 12 awg solid copper wire. And motor mount is grounded to the frame. I have tested two other spark plugs and have also ohmed the stater and coil. I am completely at a loss. I cannot achieve spark. The pictures are of me in a high state of stress so dont mind the mess also I've pulled all the tape off the wires to check for any bad places.
