So I finally became fed up with the crap chain adjustment on my Z400 and bought an aftermarket swing arm.I was pulling my G Force axle from my stock swing arm when I flipped it over and found this.

It's cracked....and not just a little bit as you can see. The last pic if you put your finger underneath you can feel the crack going back atleast an inch towards the linkage mount. If you look inside the swing arm you can see cracks that aren't visible in the pictures. Keep in mind that I don't jump often and when I do it's nothing harsh. About the harshest I can recall was flat landing from about 3ft. Just last year my brother's Z had a hairline crack form on the top near the factory welds. We drilled the crack and had it welded and has since been fine. My swing arm showed no signs of cracks on the top, this is just on the bottom. So I decided to check his out last night.
No where near as bad as mine and I was able to get a pic of the crack on the inside. Mine has this same crack as well. The last picture is how the first crack on the top of his swing arm was repaired.

Both bikes are 07's. Both see very little jumping at all. This is unbelieveable.
