I then took the 2nd unit I had that made spark and didn't rev and baked that one for 20 minutes. connected it and kicked it over. She fired up, and revved just like new. How it works I have NO idea, but it does. "
i've tried it with a dead CDI once. may have worked better if i didn't have a really bad short term memory. put it in the oven, got distracted... a couple hours later i walked into the house wondering what that smell was.
the CDI did work for a short time afterwards, though. bike fired up and was somewhat running OK. can't say i'd trust it for a long term solution... with my luck it'd work great until i was 100 miles from anywhere in the middle of the desert...
