Hey everyone im new around here and just recently started riding. So here is my situation. I ride a 03 r6 and unfortunatly the chain was thrown off the front sprocket consequently leaving a hole in the crank case. So in my current financial state I could not afford to buy a hole new engine so i mended it with JB weld. It seemed to do the trick no oil leaking from the crack area. But here is the problem. Just sitting there the bike does not leak any oil at all, but once I start to ride it that is when it starts to leak. Why would it do this? If it only leaks when the bike is on and in gear and moving where are the possible spots It could leak oil from? Any help on this would be great. Like I said at this time I can not afford to put another engine in my bike otherwise that would be my first move. I just need to get my bike running with out the leak because it is my only mode of transportation. Thanks in advance.
