Will the Wr450 crank work in the YFZ450?? I want to put that TUmic Racing 480 kit on this thing but need a longer stroke for the cylinder to work. Does anyone know how to go about doing this?

 

Thanks , the TUmic kit consists of a YZ450f newly designed cylinder at a 98.1mm bore, with stock YZ stroke. Could JEpistons possibly build a custom piston with the pin located lower to accomadate for the difference in stroke?
