Check this out. I bought this sled a couple weeks ago ('00zr700). The crank snapped off at the clutch. I was pulling the clutch apart today and found this. I assuming this crack happened first loosening the clutch and causing wicked vibration until the crank finally snapped. At first I though maybe the came off at high speed on the previous owner the the banging around in the pan caused the crack, but the pan is fine, only some loose rivits where the belt guard attaches. I would have to assume if this thing came off at high rpm and banged around enough to cause that crack, it should have came out the side of the sled too. Let me know what you think.
