Hi all. Picked up a 2004 TE 250 with no spark. After doing some basic testing and being told the CDI had gone I got myself a Vortex CDI for it. Put it in and still no spark. Tried a few things and then tried an old plug. got spark?? Went down the shop and got 2 new plugs, put them in and no spark from either. Put an old 2/stroke plug in the cap and got spark. This got me thinking that maybe my stator is not producing enough spark to fire the new plugs but will fire the old ones. tried starting the bike with an old plug I found that fitted and it would fire but not run. Is there a test I can do on the stator to see if it is producing enough spark? Cannot find anything on the web so I am looking for what readings I should be getting. Anybody able to help? Don't want to send out for repair if not needed. Thanks
