I buy the cheapest chains possible and keep them scrupulosly (sic) clean, and boil them in used crancase drippings from my wife's Hondacar. Don't need no stinking o-ring, x-ring or fancy-smancy chains. Also use a quality chain lube like JT. I have never had a chain fail (except back in the bad old days when my 25+ hp AT1MX would throw the dinky 428 through the cases on a regular basis).
