iv got a speedfight 100 and i am swapping the engine for the same engine is it just an easy in and out thing, someone has mentioned to me something about the stator may need changing so not sure??
Re: engine swap I did this on a 50 for a 100 and the stator had to be changed however if it's 100 for 100, providing there's no differences I don't see why it shouldn't be in & out.
