Sorry to bring this back up again ,I've now got my 150cc big bore kit and planning on installing it this weekend if I have time and was wondering if anyone can shed some light on this sai hole that you need to fill wondering where abouts it's located ? and will epoxy weld itself be enough to fill it ? I have included a pic of my own kit image.jpg is the hole you need to fill the one on near the top left hand side 2nd one down?
