Title: Easy one... (rocker oil pipe routing)
Post by: Steverat on 06.02. 2019 13:09
I m at the stage in Josef's rebuild where the rocker oil pipe has to go on.
Now then, route it down infront of the seat tube or behind?

Mine is routed at the front/drive-side of the down tube. The rubber filter boot touches it.
I suggest making a mock-up from something suitable, such as metal brake tube so you only have to bend the real pipe once.

Infront I'd say

    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.

Photos of my (mainly original) 1960 S/Arm.
As Swarfy says, across the top and down the right side to oil tank.

(Edit) For 1960-62 rocker pipe is in two halves and joined by a rubber hose to alleviate vibration stress to fixed ends

Don't forget that Steve's project is a Plunger. Pipe is continuous.
