Pulled the pan on the stock 200-r4, due to a leaking gasket and this is what I got! It still worked when I parked it, but wasn't shifting properly at WOT. It had a pretty bad leak, so I assume I overheated it and caused this part to fail. Question now is, Do I rebuild it myself or take it to a pro? I am in the Phoenix area but I am new to the scene so i dont know a good builder. Any suggestions?
