When you checked coil, I'm guessing you mean resistance. Check for pwr on the 1 wire when key on or cranking. The other wire goes to cdi box, controls coil. If you have pwr there, then you need to look at timing sensor, wiring to cdi, or cdi itself. Timing sensor is mounted in with stator. Hope this helps.i have a 700fi,, no fire to the plug,and the coil checked good,, engine turns over good but no fire... can you help,, thanks "Diveman"
