Just discovered a pair of cracks on my yakuza's swingarm. It looks like it was overtightened and the CNC bit broke underneath. It looks like the hardware may have worn the frame and caused a bit of a gap, and then when the bolts were tightened, the frame cracked. I've since added a spacer, and the cracks do not seem to get worse with the shock in and tightened down. Should I be concerned about this, or just go for it? Cracks are usually dealbreakers, but I don't ride super hard or aggressive, and the nature of the crack SUGGESTS that it might not get worse as long as things are tightened down appropriately. I'm not a mechanical engineer so I can't really "eyeball FEA" that section, but it looks like shock forces should be going opposite where the cracks are located. I'm eyeing up a couple of replacement frames to pilfer the swingarm off of, but riding it would be cheapest.
