No probs Trev., I'd say I'm in as deep as you *smile*, and i did have more of a look and found that the M16 x 1.5 is very close to something like UNF? @16TPI? OR NPPT or something I'll have a look at when i stager back to the Chaparral later. ..or is it the Ponderosa   *conf*

 Forget most of that- the 5/8" UNF 16 TPI has magically ceased  to exist, also NPPT turns out I was thinking NPS- not either..... *dunno* *dunno*

For anyone using the Norton oil filter head and needing the Citroen 2CV spin on filter - I've just bought some of the Borg and Beck version reference BFO 4180.  They are painted black and the only text is on an easy to peel off sticker, so look reasonable if the filter is visible.

Greybeard,
I also found that size does matter; I had to custom make a head, to get it to fit in plunger & rigid frame toolboxes..
Takes a standard element however.

I've just put my oil filter under the swinging arm. Used a B&S spin on (2"x 2 3/8") p/n 795990. Copied Orabanda and machined an alloy adaptor. A little bit of fiddling and bracketry but i'm pleased with the result.

Put mine under the carb drip tray its flexible enough on the rubber hoses to turn it over and replace the filter once i remove the bracket .

I think that 20/50 is so cheap that regular oil changes make a filter unnecessary.

Easier to change a filter than clean a sludge trap …. Spent too much money on my rebuild to not run a filter.

My machine is 64 years old and has +.020 pistons and one undersize on the big ends. That by my assessment with modern detergent oil replaced every 3000 miles minimum gives me at least another 64 years of gentle motoring and my bike is in completely original spec. I know that many will disagree but I see very little point in belts and solid state electronics and aftermarket gewgaws on an old machine. I reserve the right to change my mind if my knees give out and I need an electric start obviously.

Oil circulating in an engine is much like water in a river - sediment drops out when the flow slows down so, in theory, contaminants in the oil should drop out in the oil tank. The other place, as we know, is the sludge trap (which acts as a centrifuge). What worries me about using detergent oils in old engines is that they're designed to keep contaminants in suspension so they can be removed by the oil filter. With no filter fitted, the muck keeps circulating without dropping out, acting like a grinding paste between oil changes. Presumably the centrifuge will still perform (I recall a certain make of car, Fiat I believe, which used a centrifuge on the crank as its sole filter) so that should remove some of the contaminants. That said, I'd rather clean out the tank now and then rather than make regular visits to the 'sludge trap'.

Perhaps someone with a bare crankcase on the bench could advise of the feasibility of making access to the crank through the timing side, to enable the sludge trap to be serviced in situ? Assuming, of course, no-one has gone overboard staking the plug. Frankly, I don't see the need for that.
