so I'm a bit confused by this, hoping for some insight. 1978 KZ650, head recently serviced by APE, with a valve job, guides, springs, and seals. kept the original pistons and rings because they looked good. It smokes pretty good on accel, smells like oil. I did a compression test and its was 150,145,150,155. I also did a leakdown test and all cylinders are less than 1%. Is it possible the rings are leaking with good compression? Its either that or APE did not install new valve seals or installed them incorrectly.
