[QUOTE="MarBl, post: 156696, member: 4437"] Thats certainly good advice, but out of reach for me. Even a non-refurbished K2F is kind of a rarity here and there are no bargains I know of, not to mention any knowledge about the armature it will provide. So an attempt to collect a bunch of armatures to chose from would be at least a quite expensive enterprise with its own uncertainties. Also stress-testing inevitably requires higher temperatures and for me as a standard user/rider without professional equipment that means "drive it until it fails" (which in my case was kind of fun. I remember pushing the bike home one day and thinking "Man, this thing looks so good its even fun to push it and admire its beauty while doing so" Most "noteworthy" failures of magnetos I know of are winding-related. You can tell because (as also in my case) they still fail the same way after everything except the winding has been repaired. That characteristic failure is the common "runs until it gets hot, then fails and runs again after cooling down" Of course I dont have any statistics but from my observations I would infer, that the winding issue is the main reason, why people walk away from magnetos. That doesnt say, that it fails more often than condensers (or other issues). But whilst the latter ones are also successfully repaired more often, it usually ends with the search for a reliable rewinding. At least that is what I hear from discussions and experienced myself. Having said that, I would never replace a working magneto. I really love the concept and technology. But when its winding fails, I go electronic. [/QUOTE]
