oil return

Blimely man, how else are you going to be safely assureds that the oil is circuiting?

You strike me as someone who has no mechanical sympathy

Oil pressure gauge.

Return flow doesn't mean much. You will have return flow even if the conical oil pump seal or crank feed seal were missing, but no lubrication.

Good idea and better than nothing but the oil will not make its way onto the actual lobes until the Cam rotates bywhich time it could be scuffed

Then , where does the oil drain to from the rocker cover?

Well it passes between the cam followers as they are moved by the rotating cam , but this is not aligned with the lobes as such. Jseng 's BSA tappet holder gets round this to some extent - because they are drilled in alignment with the cam lobes . However the main lubrication to the cam is random spash and mist from a running engine , you will not replicate this by endless kicking but simply scuff the cam lobes..

I think if you dump a load of cold new oil down the pushrod tubes, it’ll flood the followers and as it runs down some will drip past the cam into the sump. But some will naturally adhere to the cam follower, run around and coat the face and run onto the cam.

Even if most of it ends up in the sump, it’ll be whipped up by the crank when it starts up.

Either way, it’s bound to help somewhat, and can’t do any harm. And HAS to be better than allowing a dry set of cam and followers to grind against each other !

And, considering that when the engine is running, the whole top end & rockers are just about fed from the scavenge oil return pipe on the earlier Nortons- at least you are pouring fresh oil to lube the camshaft & followers!

It’s not an “earlier Norton.”

what a load of fuss ! if your that worried take the rubber line off the return metal pipe coming out of the crankcase and kick it over a couple or five times and almost without a doubt you will see oil emerging. Once done connect back up and start bike and give the pipes and filter time to fill
