I just noticed a very small oil leak coming from under the left side crankcase cover, maybe 1 drop every 3 or 4 minutes. Looking closer it looks like I hit something, or something very hard popped up and hit me. I jumped online and was prepared to order a new cover, but then wondered if such a small puncture could be welded or even JB welded? I have always replaced covers when cracked, but have heard such minor injuries can be easily repaired with JB weld or other such products. This bike has approx. 80 on hours on her, would it be a stupid risk to JB weld rather than replace the entire crankcase cover?
