2. standard cylinder.....bore shape is oval rather than round.
3. rebored.......+ 030 etc.....-poor hone ( wrong grit or hone angle).... cylinder still has boring marks in it.
4 excessive piston to cylinder clearance
5 incorrrect ring set for your application.
When you pull it down as its your first build ,it would be well worth a trip to an engine rebuild shop to have it measured.
Putting it back together the second time to have the same problem would do your head in.
