The following are reminders for piston installation:
PISTON
Rub a small quantity of SUZUKI MOLY PASTE
onto the piston pin.
Place a clean rag over the cylinder base to
prevent piston pin circlip from dropping into
crankcase, and then fit the piston pin circlip with
long-nose pliers.
CAUTION:
Use a new piston pin circlip to prevent circlip
failure which will occur with a bent one.
When fitting the piston, turn hole on the piston
head to exhaust side.
Before mounting the cylinder, oil the big end and
small end of the conrod and also the sliding
surface of the piston.
CYLINDER
Fit dowel pins to crankcase and then fit gasket.
CAUTION:
To prevent oil leakage, do not use the old
gasket again, always use new one.
Hold each piston ring with the piston rings
properly spaced and insert them into the cylinder.
Check to insure that the piston rings are
properly inserted into the cylinder.
NOTE:
When mounting the cylinder, after attaching
camshaft drive chain
, keep the camshaft
drive chain taut. The camshaft drive chain
must not be caught between cam drive chain
sprocket and crankcase when crankshaft is
rotated.
NOTE:
There is a holder for the bottom end of the
cam chain guide cast in the crankcase. Be
sure that the guide is inserted properly or
binding of the cam chain and guide may
result.
