Rebuilt front forks and rode bike with no problems.  Week later, bike will not start.  Pulled wet plug, cleaned and sparked thru push mower but will not spark on bike.  Consulted manual.  Continuity checks ok thru neutral safety switch and kill switch.  Spark plug coil: primary .2 ohm, secondary 5.612 k ohm.  Magneto in question; 1.645 M ohm; primary 7.29 M ohm, secondary 14.38 M ohm.  Converted ohm readings and points to magneto but unsure,  TPS untouched along with carb.  CDI stock along with rest of bike.  Need help!
