I DO NOT HAVE OIL PRESSURE ANYWHERE IN THE ENGINE
I took out the bulb I bought a flexible and an oil pressure clock I PUT EVERYTHING NEW I also have no pressure.
I explain: before placing it, I had him absorb the oil manually, at that moment I started to ride it and he had good oil pressure, but when he stopped it later on the engine and tried to start it again to get out, stop absorbing oil and there the problem.
Did they replace the oil filter? This brings an internal limiting valve that can be locked. It is not common, but it happens.
Check that the pump is rotating. If I'm not mistaken, that motor spins the pump with the auxiliary cam and the distributor shaft. Can you tell me what engine it has? Is it the AP engine that brings a mechanical distributor?

So is
Yes. It is the classic AP. The oil pump shaft rotates through the distributor shaft. If you take out the distributor, they will see the pump shaft. They can turn it with a drill and see if it gathers pressure. That way they are discarding. If it doesn't pump, it's the pump. Otherwise, check that the mechanism works well or possible blocked ducts.
