I got a horrible knock in my backup bike a few months back, just getting around to tearing it down to start prep for 2011.... Gold flakes in the oil, which I was told is a good indication the bottom end or rod bearings are f'd.... So my question is what would you guys do?? It's an 06 gsxr, so engines on ebay are plentiful, but there is no guarantee another motor won't go boom. Spend the $$ and make a bulletproof SS motor, or take my chances w/a used setup and save a couple bucks? Or... anywhere I could buy a prepped/built motor outright?
