aprilia sr125cc 2 stroke cylinder kit

hi replacing the cylinder and piston on my aprilia sr125cc 2 stroke engine .the new cylinder comes with a head gasket but i checked aprilia site and they dont list a gasket and there wasnt 1 fitted with old cylinder.also is it worth gapping the piston rings as there were no instructions in the box and also does the r on the piston rings face up.

 

Std 125 or 172cc?

 

its a 125cc cylinder kit from ebay

 

just checked the ring gap and its 0.30mm

 

Can u take some pictures from the cylinder outside inside ?

 

The genuine cylinders don't have a gasket !
