On an '87 XHL 1100, It is coming apart, partially, to be painted and a topend repair. Noticing the oil lines are hard and it has the occasional drip. Underside is oily so I am wondering about changing all of the oil lines. Has anyone ever tackled this? I've never really dealt with Sportsters so I am a little on the ignorant side. I am going past the owner's home today, I plan on getting the service manual she has and looking through it.
