Hello everyone, These forums have been of great help to me over the last few months, and I find myself now in a situation that demands I ask the more experienced for help. My XL600 recently started spraying oil out the engine for the first time. It would appear that there's some kind of plug missing that I've never noticed before. I haven't crashed or dropped it since I got it (the scratches have been there since my purchase). Does anyone know what part is supposed to go into that hole, and where I can find it (if it's something that I can replace myself)?
