Speedight/Vivacity interchangeability

Hello guys, doing an engine swap on my speedfight 2 50, for a vivacity 100 engine. Don't want to use the vivacity loom so can I just use my 50 stator in the vivacity 100 and use my existing loom?

Many thanks

 

Yes, you should be OK to do that. They should be a straight swap. Make sure that you tighten the flywheel nut correctly and use some thread lock on it. Oh, and don't forget to tell DVLA about the swap and the new engine number

 

Thankyou
