! CAUTION Make sure circlips are firmly seated and the open end is directed either down or up before continuing with assembly.
11. Install the cylinder base gaskets onto the crankcase making sure each gasket aligns with crankcase transfer passages.

! CAUTION
12. Rotate each piston ring until the ring ends are properly positioned on each side of the ring keeper; then apply oil to the piston assemblies and cylinder bores. Remove the rubber bands from the connecting rods. Fig. 2-257
Incorrect installation of the piston rings will result in engine damage.
8. Apply oil to the connecting-rod small-end bearings; then install the small-end bearings into the connecting rods. NOTE: Apply oil to the piston pin before installing.
9. Place each piston over the connecting rod so the arrow on the piston dome points toward the exhaust port; then secure with a piston pin. 726-306B
NOTE: The arrow is found either up inside the piston or on the dome top.
10. Install the new circlips so the open end is directed either down or up.
NOTE: Apply a generous amount of oil to the surfaces of the pistons, rings, and cylinder bores. NOTE: Inspect the cylinder-base gasket to ensure proper positioning.
13. For each piston, place a piston holder (or suitable substitute) beneath the piston skirt and square the piston in respect to the crankcase; then using a ring compressor or the fingers, compress the rings and slide the cylinder over the piston. Remove the piston holder and seat the cylinder firmly onto the crankcase.
