Somebody throw in a little punctuation once in a while.  Makes the read easier.

 

IF the YZ engine is a 400 or a 426, then the stator and flywheel will fit, and the engine will bolt directly in.  If it's an '02, you may have to swap the steel inserts at the rear of the engine with the ones from the 400 so the swing arm pivot will fit. 

 

Be aware that the YZ will also have a close ratio gear box, so low gear will be a little higher and high gear a little lower.
