piston ring install

1- Remove and clean old cylinder and piston- It is best to emory the cylinder in a 45 degree

    cross motion from the bottom of the cylinder. Check for all rough edges and scoring, 

    then flush with raw fuel.
2- Carefully install rings on a clean piston, take care to align the groove pin with the ring ends,

    turn the cylinder upsidedown and install  the piston carefully down to the wrist pin hole. 

    (SEE VIDEO BELOW) - Note: Arrow on top of piston points toward exhaust .
3- Replace base gasket  and slide cylinder/piston combo onto cylinder studs, align rod with

    wrist pin hole, install pin and clips. Insert cylinder the rest of the way to the case.
4- When starting for the first time, kick over gently and do not rev engine excessive until rings

    have worn in.  It is sometimes best to allow the bike to idle for a few minutes, let cool and  

    repeat several times to allow rings to properly seat within the cylinder.

HINT:  A little extra 2 stoke oil will never hurt on a new set of rings.

We no longer replace RINGS - broken during shipment.
