Any suggestions for a manufacturer/model for a 69 500cc, also if installed would the guaze filter in the oil tank be eliminated ? Thanks for any advice

Hi Argie, you could use the one from a Norton Commando. It fits in the return line but the gauze in the oil tank still remains. It does however filter the oil BEFORE it goes back to tank AND gives a little extra capacity. You can fit it below the swing arm on the frame down tube, easy for removing / fitting and allows you to flush the system at oil changes.

How did you attach the oil filter to the frame - custom installation?

Argie,
Take a look at this link - http://www.britishspares.com/16.php

They normally come in kit form, with everything you need to connect them up, uncluding the hose ,specific to your year/model.

I would suggest most Brit spares suppliers would have similar kits.

I fitted one to my 77 in 40 minutes, and no hassles.

Note that these things won't cure a partially or fully blocked sludge trap....but can drastically reduce the blockage of a new one.

Hope this helps

Ozbloke is right there, but if you just buy the Commando head unit it is a custom job to make the mounting. I used a clamp from a car exhaust and then a drop plate to fit the head of the filter unit.
