Hey there pretty new to the seen. I recently picked up a chinese clone of the Honda CRF70 I believe. Anyway I test drove it before I got it ran great, then got it home and took it out for another spin samething it worked great. I left for the night after that then today when I went to ride it she wouldn't start. Upon further inspection I noticed there was no spark and the spark plug was all covered in black stuff. So off to the store I got pick up a new plug try that samething no spark. I did a compression test and everything seems to fine. So this leads me to believe its something electrical my guess is either the Iginiton Coil I always hear about them going on these little china clones and my second thought if not that, would be the CDI? Just looking for your guys input on the whole situation. If I did end up having to replace the CDI box would I have to replace the whole wiring harness? Usually theres like a 5 pin molex connector or something, however on this bike it seems the wires going directly into the CDI, so would I need a whole new wire set as well if replacing the CDI ? <--- Im more stuck on this then anything. Thanks in advance to anyone who sheds some light on this !
