I had a friend with one of these that he couldn't get running. He brought it over and I changed the cdi module. It was really cheap about $12. Then it started having all kinds of electrical issues. Turned out what looked like 18 ga wire was 24 with a really thick jacket. It seemed every time I got it running something else would stop working. One day the overriding clutch for the starter went out about half a mile into a trail and it spun the starter constantly. Made it back home and got it fixed. The engine was really great, but the electrical system was horrible. Loose crimps in the connectors and just sloppy wiring. There's a forum I think it's ATV connection that has a section on the Chinese atv's. I'm sure they will have a blast on them.
