When you say Mount Etna are you saying oil
1) overflowed or
2) was pumping out under pressure?
Did you remove the oil lines from the pump? You have them reversed

Prince, I thought about that but the oil flow to the rockers is minimal. That's why I asked if it's pumping or just over flowed. He was under the bike so I wondered if he pulled the oil feed and return lines.

PY, did the oil/ignition light go out or stay on or did you notice?

PY, If you filled the frame up to the full mark with no regard for what there was in the crankcase, once the motor is running I would expect an overflow situation. Jack

But are we talking running engine? If you kick it and the light goes out then the pump is filling the relief valve. But this just needs to be residual oil in the line.
BUT, IF WHEN RUNNING, the light comes back on, you have no oil pressure or a bad relief valve.You have to determine which it is BEFORE you ride any more. The best way is with a pressure gauge.
But you did not answer the question: Did you remove the oil feed and return lines to work on the bike? If you did the feed line from the OIF goes to right side feed tube under the timing cover. The return is the left.
If the crank is full then it is wet sumping - another issue.
The poor mans test:
1) check the line placement and
2) if correct, drain some oil from the OIF, start the bike and see if it's pumping back from the pump. Just don't run it long. You will know in a few seconds.
Let us know

Connect the pressure gauge in place of the relief valve.

KY66 -
When you say overflowed, we assume you are talking about engine oil and I assume you are talking about the engine oil tank which is accessed from under the seat. Meaning: you removed the cap to the tank and the oil flowed out the fill cap.

If this is the case then nothing is wrong. No measurements are needed. Your bike is working correctly.

The only issue is that you've over-filled the engine oil, and this most probably by over-filling the primary case. The primary and engine oil are shared, so that when you over fill the primary, the oil pump evacuates the excess back to the tank like it should. When you take off the oil tank inspection cap, then Surprise! there it is.

If this is the case, then you really should measure more carefully as per your manuals.

This I gotta see.

I think he means in place of the oil pressure sender, not the OPRV.

Installed pressure gauge fired it up very little low oil pressure lucky if I get a reading on tickover if I rev to 3K maybe get 25psi
Bad oil pump ? or dirty maybe ?

Ouch! I have 70 PSI at 3000 and 15-20 PSI idle warm.
1) Bad pump
2) bad crank seal in timing cover
3) bad ( internally) oil line from OIF to pump
4) clogged oil screen filter in reservoir
5) garbage in feed side of pump
Good luck, don't ride it.
OK , RF and Tiger, tell him what I mean laughing
