I was trying to completley drain the oil out of my bike at my first oil change to get all the factory oil out of it. While doing this I broke the bottom corner off next to the drain plug. I have tried JB Weld and several other two part epoxies. After the first repair I noticed a small leak so that is when I started over and nothing is working. Is there anything I can try or do I just need to bite the bullet and buy a new case?
