I think they have figured out that they can't make much money on a high volume/low dollar engine. YS is a small company that is not geared toward high production of any of their line. Right now they are heavily backordered on the 160DZ which they can make reasonable returns on. I think the engine will again be available, but it will be a fill -in when their other engine sales are slower. It will probably never be available in the quantities necessary to meet the demands of the US market, consequently it will always have limited availability........unfortunately.
