Replacement oil return/feed pipe

[joebloggs]

I thought about the stainless braided hose option when I replaced mine a couple of years ago but the bolts and banjo fittings are not the same as brake ones.  The oil pipe bolts are parallel with no groove round them by the hole the oil comes through but the banjo fitting has a groove inside it for the oil to flow round.  If you used the original bolts and brake hose banjo fittings no oil would get to the head!  I have a feeling there was another issue with bolts different thread or length for the banjo part.

Any changes in the flow through the pipe could result in increased flow to the head but possibly lower flow/pressure to crank bearings or reduced flow to head particularly when oil is cold.

I haven't seen one and not at home until the weekend but I find it hard to believe Yamaha haven't used an off the shelf fastener, OK so it's unlike a brake type banjo but its still a banjo of sorts. I've looked at male male AN fittings and unless Yamaha did make there own fittings I bet it wouldn't be a million miles away from what you would need to make up a line.

I've emailed Goodridge so will see what the suggest

Did you look into different types of AN fittings. A male male could be the answer depending how the oil is fed into the original fitting.
