88cc Big Bore Kit Install Instructions
Before installing a big bore kit, you should first install a high volume oil pump. A
high volume oil pump will deliver up to 300% more oil to your top end which will
only help preserve the life of your engine. To install the big bore kit you will need
to:
1. Stuff a CLEAN rag behind the piston to seal off the crankcase.
2. Install a c-clip into one side of the piston. When installing the c-clip,
compress the c-clip just enough to get it into the piston. Note the position of
the c-clip once it is installed.
3. Install the thin retaining rings and the wavy oil ring onto the bottom of
groove on the piston. Carefully slide one thin retaining ring on, then the
wavy oil ring, and then the other thin retaining ring. Make sure that the gap
on each ring faces the opposite direction as shown in the picture.
