SO my buddy and I were looking over his square as Ive been researching motors and such on here for awhile now. We check his motor expecting a 6m6 right?! Nope found a 6R7?? What do we have in there?? Thinking maybe a 650sitdown motor of some sort? The next ? could I drop my fx1 motor in without changing cdi? Just sounded like something fun to do since Ive got it and all just takes a little time right!
