Hi - I'm trying to plumb my 1967 BSA A65 for use with a Paul Goff Oil Filter kit. The oil tank has a 3/8" outlet, and a 5/16" inlet with the return pipe to feed the rocker arms.

I've got a two tube oil feed for the bottom of the engine with 2 5/16 send and return lines.

I just can't seem to get my head around routing the oil lines so that they won't kink, or rub on the swingarm pivot.

I've attached some photos of the way that it's installed. I also attached a photo of some right angle compression adaptors that will take the 3/8 fittings on the filter attachment and take them to 5/16 so:

a) the bend wont be as drastic
b) so I don't have to convert 5/16 to 3/8.

I've read all the articles that I can find here on doing this, but can't figure out how to apply the advice I've gotten.

One of the things is that the Goff kit is 3/8" - and the return lines on the bike ar 5/16 - you're going to need a size converter somewhere - where have people put that?

I went out yesterday to start planning this out, and I got confused. I went back out again this morning, and got more confused. I figured a good place to start would be looking at how the oil pipes were fed stock, but couldn't find a good image of this.

Thanks - this forum has been a lifesaving putting this bike back together.

No harm in overthing things, my projects take me longer and longer these day because I over thing everything, For the hose conunderam just use the 5/16 hose, soften it with a heat gun or mug of boiling water and it'll go on fine over the larger fittings on the oil filter housing.

If you really did want to fit the elbows, I'd cut the original spiggots off and drill/thead them to take an adaptor for your spigots.


Im looking at your photos on a bigger screen now and can see your fittings better, they look like they are the type which would have an olive and form a seal on the pipe type?

Yep - they're compression fittings. They'll fit - barely, on the pipes coming out of the oil filter housing.

I have a degree in overthinking.

It's not a bad thing and it helps pass the time too wink
