hi Bax,

i now have 4 OS fourstroke engines. while they are running fine and new, i would like to ask about their long term maintenance as well
as what are the likely expendible items, like gaskets, or bearings, that needs to be changed, and roughly at what periods?

i hope to make my investments in OS worthwhile. i recently have problems with a saito engine 72 fourstroke, bought 3 years ago.

please direct me to this advice if it has earlier been mentioned.

thanks.
