My pipe cracked right by the turn in it, and i cant figure out how the heck it would just crack. The trails werent ruff or anything and i hadnt jumped anything that day, just did the usual wheelies but nothing out of the ordinary.
did you get powder or snow on it when hot. Maxdlx

mine cracked also and my old sx700 cracked I beleive its do to yamaha' s crappy undercut welding, probably the same process they used when welding the w arms
My pipe cracked a couple years ago on a SX500R. Sounds like the exactly same spot. It cracked right on the weld seam.
Its usually just from the heat cycles, and once you get powder snow on it, it really stresses the metal, it happens, no real way to prevent it. You can just usually mig weld it back up.
