Finally got this 110cc atv running and I found an oil leak. After a week of it running fine it started leaking oil. The oil seems to be leaking not from the oil drain plug but from what I believe is another bolt which is an oil pump plug. But its hard to tell exactly if that's where its coming from. The bottom of the motor on one side seems to be pretty oily. I'm wondering if I broke a seal inside the casing that's allowing oil to leak out because both bolts on the bottom of the engine are tight.
