[QUOTE="Tom Gaynor, post: 4841, member: 4034"] [b]Magneto problems[/b] I'm not an expert on this. The 2MTT mag on my Manx Norton has failed three times, each time when very hot - either a hot day, or on long circuits like Chimay or the Ulster GP. Two times out of three it has restarted once it cooled off a little. The exception was at Chimay where the ambient temperature was about 34 and I was within an inch of heatstroke. One piece black leathers....... I've been told by (the many) people who know more about it than I do that the problem is in the condensor, that with modern varnish the windings last forever, and that the go-to magneto guys do NOT use radio condensors from Radio Shack or Maplins, but condensors designed for the application. These are of a different construction from the usual Lucas ones. I wouldn't know if this was true or not, but believe it is. There was something on this on jtan a while back. I've always had good results on road mags from Dave Lindsley, so that's where I'd send my Scintilla. I take your point that if it ain't broke, don't fix it, however if it does stop when hot, then restarts once it cools, it's telling you something. Either start on a headstone for it, or send it to be overhauled. (This discussion is parallel to one on the Sunbeam S7/8 "jtan" where Lucas condensors are occasionally dead when they come off the shelf, having broken down in storage.) [/QUOTE]
