[QUOTE="Canadian Dave, post: 113244, member: 16102"] Hi Brenda, You'd normally expect to see signs that something is going bad, the engine will start to miss fire at higher rpms, the power going really flat, things like that. You will normally be able to limp home. The stator coil seems to be the first to show its age. Is it worth rewinding just in case ? ? ? it's a crap shoot. Yours might last 25 years or go bad next week. If you are concerned you might consider grabbing the multi meter and testing your system to make sure all looks well. You might want to pull the plug and watch for a good quality spark and monitor it over time? Carry extras? Well if you ended up with a good used CDI and ignition coil in your collection then stow it away in your tool box just in case. Problem is often times it's a stator coil, which would be a little more difficult to change out on the trail, you'd end up with a big fanny pack. A note of caution, its not at all uncommon for a CDI to test outside the ranges quoted in the shop manual and still function perfectly so don't be concerned if it's a little off. I've tested brand new CDIs that didn't match the spec. You'll want to watch for a dead short etc where there shouldn't be one rather than one circuit thats a little off kilter. Fact is if your CDI was bad it would have let you know already so I'd focus on testing the coils from time to time. You know now that you've brought up the topic . . . . . . well maybe you'd better knock on wood ;) David [/QUOTE]
