I have a 93 GSXR 750 rolling chassis that I purchased from a guy in Rhode Island, NJ in November 2014. I then bought a 1100w motor to put on this monster in January 2015 and completely restored the bike to the best I can. Took me 4 months to get this baby back together piece by piece on a limited $1000 budget, and this happens to me.
Problem is I was riding right before winter at all of a sudden, power-loss and smoke coming from engine, almost like a misfire from a cylinder.
So I took it back home and cleaned the carbs and sparkplugs because I thought that was the problem, and after all that it still ran like crap.
So Then I changed the oil and I saw cooper and metal in the oil pan and metal bits. Engine has a loud knocking sound and it doesn't rev easily. Im thinking rod-bearing has been shot.

Is it worth repairing the engine or it is better getting a new engine for it?
If I was to repair the engine, what needs to be replaced when the main rod bearing goes out? Pistons, top head, cams...
