I have a trailmaster MB200 leaking oil cannot figure out where it is coming from or what it is don't know if it's run off from when I change the oil or what? But I swap the engine with a predator 212 and I park my bike and come out always will be like a drip of oil wondering what it might be any suggestions? I don't know if I need to tighten something or maybe something came loose from vibration or riding but at this point I'm at a standstill because I don't know and I've tightened everything try to look and see if anything's loose I can't find anything loose
