all about XT CDI ignitions...
 

the stator CDI energy coil in my dr350 gave up the ghost, so went for an ignitech.cz unit that doesnt need it. it uses the bike's 12V system to charge the CDI. way cheaper than replacing the stator and no more chance for this common failure

anyway, while searching for info on how CDIs work (all my bikes been till now TCI, including my XTs) came across this site:

plenty of info on the earlier XT CDI units and even plans to DIY....

enjoy, but you must be into electronics :)

might be worth making into a stickie

Thanks for sharing!
