bsa never fitted them and there are still a lot ove them around to tell
the tale it only takes a few minutes to empty the sump with a sump kit
it takes a lot longer to fix an engine because the  anti wet sump valve failed
or you forgot to turn the tap on  the oil feed *eek*

As threatened, here is a link to the video I've done showing oil returning at idle and at higher RPM. I've also taken the liberty of including some other views of the bike for your interest and amusement.

I would be more than a little interested if any of you folks with scads more experience decide this isn't what the flow should look like, in case I need to correct something.

Like the colour scheme Richard - nice bike sounds just as an A10 should

The return oil flow is the same as mine and I don't consider mine to be too bad

Bill,

Thanks. The color scheme was nothing formal. I was at the paint shop thinking I was going to just go with black, but the painter (no classicist) talked me out of it. The color I picked was just something that appealed to me from a color chip in a book (if you're interested, PPG 5725).

I meant to mention something about the sound on the video. You might have noticed that part of the video (the beginning and end) was done in my garage and the middle part was done outdoors. This is because I had to go back and reshoot the higher RPM flow and edit-in the clip. The part shot outdoors sounds richer because it is not subject to all the acoustic reflections clattering things up as  when recording within the garage .

Thanks for the video

My oil flow is about the same, so we are finding a standard.

I could not take the bike out for a ride as its not road legal yet, but I have left it running longer and the oil return is about the same as Manosounds film. I think I was being a bit cautious. Thank you all very much for your input and great film shoot ( you must be a professional film director Manosound).
When it stops raining I will take some pictures and post them on the forum.
thanks again.

Oil flow looks good Richard! What oil is it? I've a feeling you use 20/50. It would be interesting to see the behaviour of different grades. My return is slightly different to yours, but then I am using straight mono 50.

LJ,


Good observation. It is, indeed, Castrol 20/50 non-detergent. Now, I like science and empiracal testing as much as the next guy, but I don't think I'm ready to start doing a whole series of oil-flow videos for each favored type (unless, of course, I can get Mr. Bean to star in them).

I have always wondered....

Obviously SRM do some lovely bits and i wish i could have them all, but there is something thats always puzzled me about there high delivery oil pump.

High delivery? So is that higher volume? Higher Pressure? in which case would the pressure release valve not kick in and dump the excess oil? Dont get me wrong im not decrying the mechanical superiority of the SRM pump and id fit one tomorrow, it was just a thought that struck me.

BTW you should see my Bonnies Oil return that would frighten you, Makes the BSA look positively healthy!

Speaking of oil returns if you do fit a after market oil filter (highly recommended) in the oil return, dont forget to fit it AFTER the rocker feed, and to keep an eye on the oil return when you have a filter fitted.

Steve

I'm also wondering that if you fitted such a good pump with high delivery and pressure... Would this highly pressurised oil push out accumulated crud in the sludge trap?? and therefore messing up the bearings? I would have thought that by fitting a new pump you'd want to start off with a cleaned out engine. It's a worrying thought, all that muck that is in places where normal delivery had not touched it before.

Hi LJ

I think you want to start with a good clean out make sure your oil tank is nice and clean, and run some thinner oil through the engine, then drain it, before fitting a new Pump. at the end of the day you can only have the pressure in the oil system that the pressure release valve allows, unless you "adjust" the valve with shims!

I think if you have a filter in the return and a magnetic sump plate you would be fine.
Kind Regards
