Sup guys, 2 nights ago my Ninja 250 wasn't leaking oil and it was completely fine. Last night, I went into my garage to check on the bike and I saw that there was a HUGE oil puddle on the ground. I couldn't troubleshoot the problem right then and there because I had plans and needed to be in and out ASAP. Nevertheless, I checked on it today and all the oil was gone. I narrowed the problem down to the oil drain plug being loose because it that was basically the only place where it was wet with oil. The question I have is how could the plug become loose overnight? It wasn't loose as if it was just dripping oil, I mean loose as in all the oil was gone pretty quickly. I'm guessing it has something to do with the change in weather because here in New Jersey, its cold, hot, cold, hot and changing every day, but I'm probably wrong. Any help would be appreciated.
