Mine crosses the top of the rockerbox, secured in a P clip on the right hand rearward rockerbox bolt. It then clears the inspection cover and drops down the back of the barrel on the timing side of the frame tube to join the oil return to the tank. Part of the tube is an added transparent nylon sleeve, which offers a visual check and serves to isolate vibration on the tank and fittings. Not the original layout, so your choice.
Swarfy.
Steve, Don't forget the missing stud through the top of the frame lug where front and rear sections join. Yup...looking good.
