I am looking for some advice on a stator conversion. I have ripped apart a ct2 that my dad bought in high school that hasn’t ran in thirty years. It quit on him because the ignition coil went. The removed the stator to fix it and it got lost so I have none of it. I am looked at the Vape(powerdynmo) cud conversion but it is questionable if it will work on the pre dt175 models. Wondering if anyone would know or know what I could measure to find out. I am sure this has come up before and I have been unable to find it. Any advice or previous threads on this would be greatly appreciated. 

I helped Powerdynamo put the kits together for the Yamaha 125 and 175 Enduros.  I just checked and VAPE and while they changed listing slightly fitment still seems very clear for a CT.
