My brother-in-law has a 1991 FZX 250 Engine number #YX-004942, and needs intake valves and piston ring sets. Would any one know a website where I could find these parts? Any help would be greatly appreciated. Thanks Michael (<!-- e --><a href="mailto:mpmuddinz71@yahoo.co.uk">mpmuddinz71@yahoo.co.uk</a><!-- e --> ).
