TOP RING AND 2ND RING
Top and 2nd rings differ in the shape of the ring face. Top
and 2nd rings have a letter "R" or "RN" marked on the side.
Be sure to bring the marked side to top when fitting them
to the piston.
• Position the gaps of the three rings as shown. Before in-
serting piston into the cylinder, check that the gaps are
so located.
• Place a clean rag over the cylinder base to prevent the
piston pin circlips from dropping into the crankcase.
• Rub a small quantity of SUZUKI MOLY PASTE onto the
piston pin.
