As said my experience with Wössner is not KX related it's race car related , in this world Wössner is seen as B quality to put it mildly
For example compared to Mahle the piston quality is much much less they have to spray the coating to get a acceptable piston clearance , after a few hours the coating is gone....
We had pistons which had the pistonpin desaxation to the wrong side.
The conrods are breaking the finish is terrible and the dimenstions are questionable therefor they all need a rebore to get it the bore's , lenghts and straightness right , I got one set out of a engine we got in which I didn't even dare to use.
