Replacement oil return/feed pipe

[tommyardin]

would that style pipe work? not that exact one just using it as an example http://www.ebay.co.uk/itm/Universal-Moto...Swc1FXbk7E

I'm with His Dudeness on this one if these steel braided pipes can withhold the forces involved in hydraulics braking systems then I would imagine that the pressures involved within the oil pressure system on a motorcycle would not pose a problem. The only real difference is that the engine oil would be quite a high temperature as apposed to brake fluid.
You could also have one colour coded to suit the braided pipes on your braking system.
seems to me to be win/win.
I am certainly going to look into it, you know ask the question.
