seldom but only once have heard of the reluctor pickup coil failing. Since you measured ~700 Ohms at the distributor, plug its "green wire" coax cable back in and then unplug the plug at the CDI box. Measure into the harness plug corresponding pins 31d and 7 and see if you are getting 700 there. That will check the integrity of the coax cable. These 'green wire' cables are known to crack internally, etc. so manipulate the cable in the areas near the distributor to verify your measurement is hot hopping around.
