Question on ring size for a 1999 Kawasaki KX80??

[Lon]

I picked up a 1999 KX80 that has a new top end but I some how misplaced the rings ..The piston/bore is a 47.95mm Numura piston so do I need a 47.95mm Namuar ring set??

EDITED:: Also,
Does anyone know which year exhaust fits a 99 KX80??Found one from a 95 but not sure if they changed the pipes..

BTW,
Reason im asking is they make a 47.95mm and 47.96mm ring set,not sure which one to get??Thanks in adv...
