hi in in the process of rebuilding my 1986 fz750; I need new std size piston rings and possibly bearings; or i might be prepared to go to the 1st oversize with pistons and rings; any ideas where i can source some of these at reasonable cost; here in newzealand yamaha original parts are way expensive. Or if any one knows of some alternative rings that may suit; then i am willing to modify my pistons to suit. Also has anyone tried ceramic coatings in there engine i am interested in feedback on this. Also for anybody reading this; i have heard nothing but excellent things about motul synthetic oil; and recommend this myself. iam using this in my 1988 honda gb5oo and it seems excellent.
