Crash, I don't think the role of the engine makes any difference to the requirement for good piston ring bed-in. The information in the article linked to in this thread echoes good engineering practice.
I just found this alternative link, to advice from a supplier of honing tools:
Technical information on using engine hones, flex-hones, ball hones I'd have thought they should know, if anyone does.
But the OP says this isn't the cause of his problem in any case.
