Damaged crankcase with pictures -- FIXED

I’ve patched up similar damage only to have the part fail again because of weakness/unseen damage in the area around the break. How do you test cast aluminum for cracks that aren’t visible?
 
While searching whether the Rivco center stand would work on a R3T, I came across this: . Could this be adapted to work as a center stand by adding a spring to keep it up, and adding something to push with the foot to get the bike up on it? What does the collective mind think?
 
Several of us have the Becker, and at least for me, it takes a significant pry bar to gain sufficient leverage to effectively lift the bike "over the hump".
 
I've just been looking at mine. A piece of 2" x 3/8" thick approx 16 1/2" long steel. Drilled to attach to lower rear engine mount bolt and lower front engine guard bolt. Drill and tap to mount side stand bracket. There is approx 1 1/4" clearance to to the gear-change rail. Some shims may be necessary to line it up . Also the rubber pad that the kick stand hits will have to be relocated. Should be cheaper fix than new cases. Good luck.

But you have the added lift of the slide about wheelie bit which adds about 10mm to the lift.
