Engine differences 749/999
Right, before someone says it I know 250cc !
I am considering the 57mm exhaust upgrade kit but it is made for the 999/999S. I have been informed that apart from the ecu the rest of the kit will fit the 749 fine, as long as it has the new swinging arm.
Does anyone know if the actual physical size of the engines differ or is it just the bore/stroke, just in case the 999 motor was taller or shorter than the 749 then the exhaust manifolds would not line up.
