Hi Mr Ape,
                There is a SRM article on oil pumps in the October issue of Classic Bike which is worth a read.

They suggest BSA's machinery was pretty worn by the 70's so tolerances were not that great, they (I so do) I use the best from a number of secondhand parts. Even their new oil pumps are built using selective assembly to ensure the best performance.

Considering the cost you might incur building a secondhand unit, their new pump might be a better option.

Best wishes...

Hi,
    Draganfly list them as 5/16" and they are not too expensive from them:

https://www.draganfly.co.uk/index.php/bsa/bsa/a50-a-a65/1971/category/371-frame

Strangely the oil feed pipe at the base of the engine has the return O/D 3/8", the flow 5/16" O/D and the rocker feed 3/16".

Best wishes...

Hi,
     A few photos of mine, I used plastic pipe such as this

https://www.carbuildersolutions.com/de/oil-pressure-gauge-tube-18-npt-female-end-and-18-bsp-female-with-male-cone-end

The gauge is glycerine filled to reduce vibration fatigue. A folded stainless plate fitted and secured under the clocks.

Hi,
    Looks like they are fitted to competition models, probably to reduce the fork damper travel for better control and leave more stanchion in the slider for addition strength during arduous conditions.

Hi Julian,
              Interesting document. I haven't had an issue, I do regularly check fastenings throughout so I guess I wouldn't.

Hi,
    I had similar problems, to narrow identification:

1962 - 1969 Valve guides are this shape   https://www.feked.com/bsa-a50-a65-bronze-inlet-and-exhaust-guide-68-0809.html
1970 -1972 Guides are this shape   https://www.britishbikebits.com/valve-guide-g542pb-bsa-a65-1971-72#.WdkVQ2hSyUk

1962 - 1968 The two rear head bolts are 5/16" diameter
1969 - 1972 The two rear head bolts are 3/8" diameter

1962 - 1970 The rocker cover studs are 1/4" diameter
1971 -1972 The rocker cover studs are 5/16" diameter (the rocker cover has the head-steady bracket, hence the larger studs)

I also used the valve specification as Julian previously posted.

From your posted images you have a 1969.

Hope this helps....

Hi,
