Rex speed shop RMK6-12V on 74 Dt 250 upgrade from 6 volt to 12 volt timing issue was created by Ericb1318

Has anyone upgraded their 1974 dt250 to a Rex’s speed shop 12 volt kit?  The actual kit is a RMK6-12 volt. I’m having a heck of a time getting this thing timed. I have the timing light on it and it is about perfect no matter how much I rotate the stator. Rex suggested rotating it 1mm at a time which I did. The bike will run and idle fine. At 5500 rpm it starts to cut out. Was running fine before I put the kit on it. It has always been finicky with timing but I can’t seem to find the sweet spot this time. Any help will be much appreciated.
