Posted April 11, 200519 yr Hi all, I'm considering putting a YZ250 engine in my SZR660 chassis (660 engine long gone, RD350 YPVS waiting in its place) to go racing in the Bemsee MiniMono class. The only (obvious) hurdle is the cost of a good, late model YZ250 lump. Does anyone have any idea how much a '98-on lump would cost? Cheers, Mick.
