Hi
After a recent top end rebuild with modern slipper pistons and new rings, I found that turning over on the handle there was plenty of compression "spring" but pleasantly surprised to find reduced frictional drag compared to the previous pistons. The 6V starter motor now turns vigorously. I followed a typical run-in procedure as advised above of normal road usage and frequent oil changes, but there was no noticeable tightness - the main problem was avoiding the temptation to use too many revs. Right from the outset oil consumption has halved compared to the previous setup.
