Hello everyone I have a 1994 CR250 that needs a left side crankcase. A 1992 -1996 will fit, but no one on earth has one do not no why it would be so rare. My question is if I use a matched pair say just off hand from a 1998 would any one know if my internals and top end would work doing it that way with both sides from other years. And if this is possible would any one know possibly what year or years that I could use. Any help would be greatly appreciated. Thank You 4423mark.
