What brand???...Which vendor???...What Size Piston???...Is it low pin or high pin???...What motor is it going in???...I see there is also no needle bearing and/or bushing for the wrist pin...Your gonna need one...Also are your intake and exhaust ports on the cylinder jug a comparable size as the windows???...etc. etc. etc.

And just let me add this as well...A windowed piston is designed to work with a reed valve.

The piston is a 47mm high hole I found on ebay the piston is also going in a 66cc reed valve setup. The cylinder has a boost port, a third transfer port and intake and exhaust has been ported
