Last summer I started noticing the skid plate always had some tar in it instead of just dirt. By the end of the summer it would occasionally micturate upon my rug, man, progressing to always leaves a spot... Full careful oil change in prep for spring, with the full KTM rebuild kit, removed o-rings and replaced them all along with screens, crush washers, the lot. Squeaky clean everywhere and I hung the plastics back on but left the skid plate off. Warmup, fill/top, ride. No oil, yay! Yeah it's back. Guess it just took a while to migrate enough to start to drip again plus new oil is so clean Over the last month it's dripped enough to warrant keeping a pan under it at all times, so I started carefully peeling pieces off to see if I can spot the real source, I think it's coming from the oil tank sender line, that has the conical screen inside of it. That's such a simple connection, flat plastic on flat metal, I'm not sure why it would start to ooze and get worse. Torque is correct, I thought the mating surfaces were clean. Any ideas on how to stop it since there is not an o-ring or replaceable of any kind that I remember or see in this drawing?
