Here is a link that you may find very helpful. It is on a site called Scribd. http://www.scribd.com/doc/3829256/suz-FA50-service1980.
It is a service manual for a 1980 FA50 but the bikes did not change much during the years and it should be the same. I have been using this book on my own bike. and am going to use these piston ring gaps for when I do an overhaul on the engine. I believe it is on page 66. Good luck hope the link works. Also if it doesnt work go to www.sribd.com and search for a Suzuki FA50 manual and it should come up.
