I bought a CRF250X last week. I took it out on Sunday and it ran great. After it cooled down it's almost impossible to start. I posted the story here: crf250x-mega-thread.
In the course of troubleshooting I checked the resistance on the ignition coil. The coil pack secondary resistance is good @ 5.67 kOhms. However, the resistance across the connector terminals is 0.7 ohms. The spec range is 0.07-0.10 ohms which puts mine at 7x what the upper limit should be.
How critical is this measurement? Obviously it's out of spec and I'm going to replace it, but does anyone have any first hand experience with how much that impedance affects function? Could this be the cause of my hard starting issue?
Thanks!
