Secrets of a CB750 early K

Trigger:
I have many people state that the oil jet is part of the head on a Sandcast, Diecast and K0's. But, I have been removing these for years to be cleaned out properly. They are a well engineered part of the head and come with a strainer on the back and a nipple facing up. If the jet has no nipple, this means that someone had drilled it out before, trying to unblock it.
This can cause many problems as the swarf then sits in the strainer or the drill has gone through the whole part.
Here is a couple of pics:

You are never too old to learn something new. Dont supose the later jets will fit the early head?

Interesting Graham. Never really looked closely at mine. So if they have been butchered what's the solution other than get Rich to make them ?  Those tiny strainer holes look like a challenge, although my mate in Cambridge has the tiniest holes cut in metal that I have ever seen  by laser I think. Any idea of the diameter of the strainer holes?

See you got that new camera I suggested you buy BTW  ;D ;D ;D ;D ;D ;D ;D ;D ;D

No such luck Bryan, I did try to get a few made some years ago but, they are over engineered and no one would even take on the job.
