Hello Tukig,
Similar occurance happened to me after the first engine rebuild I did, knowing nothing, "Huh, what's a sludge trap?" Results very much like yours, but without the bent rod. In my opinion, the engine rebuild is an easier and smaller job than bringing a project bike up to show condition. Additionally, if you get a new bike, you still don't know what's below unless you buy it from SRM, or the like. Rebuilding your own engine means knowing what's in there and, therefore, having only oneself to blame if things go wrong. Not saying you're laying blame elsewhere, but now you have the benefit of your own cautionary tale, at least that's how it worked for me.
