04 sportsman 500HO question

I have a 04 sportsman 500HO that lost compression! I tore into it and found the wrist pin had seized in the connecting rod and piston. I got the piston cut off and finally broke free the wrist pin. However it left a few small burs in the connecting rod! Can I smith them out or do I need to get a new crank? If I have to get a new crank where do you buy them from? I can’t find them anywhere on the net! Any help would be greatly appreciated!
