I use 6 ounces in mine, I think 8 would be too much and cause slippage.

It's been a while since I watched the oil flow from the primary chain oiler, but the amount of oil is about what I remember. The chain does a good job of slinging the oil around to the parts that require it. But I did incorrectly remember that the screw on the oil pump controls oil to the rear chain.
That said, many people eliminate the oiler and return because you are cycling oil from the primary that likely has some metal shavings and clutch material into the engine oil. And, notice that they do not do it that way on newer bikes. I changed mine over a long time ago and simply change the primary oil once a year.

I was talking to a guy I know and he picked up an older build from the 90's. While looking the bike over he noticed a small filter in the hose coming from the primary oil return so the oil was filtered before it made it to the engine oil filter. Thought this is interesting so I mentioned it. The guy that built it has a reputation of being above average.

I can see the advantage of having a filter in the return line ,but you would have to vigilant on cleaning/replacing it to prevent restriction which would allow an excess amount of oil in the primary which would be a problem.

Not saying your setup is wrong, but I was surprised by the amount of flow. Never looked inside my shovel primary while running.
My surprise was from my experience dialing in the primary chain oiler on my Flathead. She does not recirculate the oil, so completely different animal. But the rule of thumb there is 2-3 drops of oil per minute. Again, completely different animal. That amount of flow on a non-recirculating motor and I would be out of oil in 15 minutes.
Very interesting.
