I have a chance to get an FX140 (998cc) with a thrown rod at a descent price and an FX engine(1052cc) to go in it. Can I swap engines? What differences is there in the engine when swapping? Any serious modifications or just a simple swap? Will the FX engine use the FX140 computer or do I need another one? This would be my first 4 stroke experience. Any help would be appreciated.
