With fresh rings you should not see any visible smoke. One thing most do is to install the piston and rings without checking the ring gap. Especially when installing a new bore the rings need to be gapped. Rule of thumb is .004" for each 1" of piston diameter. Many of the kits the rings will have less then .003" gap. Then when the engine gets hot the ring gap has closed causing ring bind which will lead to premature ware and or broken rings.
