Hello, i just figured out my oil leaking problem. There was fishing line wrapped around my front sprocket shaft. The fishing line melted and wrecked the bearing that houses the shaft. The line wore my engine case a bit, I dont think it will be a problem if I can put a new bearing In there, does anyone know how to fix this? Is it hard? I thought the oil was coming from the crankcase gasket? I was wrong

HELP!!!
