Piston clearance for the 69,5 mm WW crank
In the end I did chose to do the Okrasa modification as well as shaving off 4 mm at the bottom of the skirt. Above you see a simpel sketch of what I did. I have included the distance from the piston pin center just so you can double check if you have some high-compression or stroker aftermarket pistons. In the end it's the pin position that determine what you need to do with the skirt.
Disclaimer: This is how I have done it. At this point in time the engine is only dry mounted and not started. This can act as a guide for others, but you need to think, measure and take responsibility yourself.
