Have you ever updated the ceramic plungers to steel?
If you haven't, STOP DRIVING NOW!!!
Hopefully one hasn't pulverized and has now contaminated your oil with ceramic dust.
If you have and that problem is taken care of, it shouldn't be too hard to locate a newer 2 cylinder version from a wrecking yard, then have it rebuilt and put on so you at least have the updated version that parts are available for. You will need to change some fuel lines as well when updating.
