After it has cooled re-install the studs cleaning them and the cylinder using acetone. Lock tight and torque them to specs. The reason we install the studs and then bore the cylinder is because there is a bulge at the top of the threads that go into the cylinder that pushes the aluminum into the steel sleeve and pinches it. You may not see any difference in your cylinder after boring it but once you ride the machine and if you have installed the cylinder studs after you bored it, you will get 4 tight spots where the studs have been tightened down after boring.
