"Very few of our members cross the floor, and I suggest even fewer do it because they are persuaded by the arguments of others"

The OP did just that. Was planning to install a valve, asked for info, weighed that and did a 180.
Me too. I wasn't aware of these valves being fitted and oblivious to the auto version on mine, until a previous re-run of this topic, last year. But I look forward to feeling the same way as @SteveA, as it might mean I'm getting through the steeper part of the learning curve!
 
$3.99 US for two ball valves.

I would never suggest anyone use one. I can talk about using one though. And yeah this is a dead horse (saying it is a dead horse is a dead horse), but how do you shut up a bunch of old guys that can't be told what to do and like to type?
 
I would say a very high percentage of threads on the forum have been covered thoroughly in the past. Using the search feature can help folks avoid repetition, but I frequently am unable to pull up specific threads I know were made in the past on topics I need to ask about. Something in the way the search tool works, fails to find them, or only pulls up only individual posts with a keyword (which can be many,many pages of posts from a single thread) rather than a thread title. This makes wading through unwanted search returns quite tedious IMHO.
Go to Google and type in what you are searching for, then add "accessnorton.com" in the search bar as well, and that usually gives good results.
 
I decided to get rid of the check valve that was installed on this machine wondering whether trust could be put in a very fine spring securing a ball against a seat failing and possibly getting lost inside the engine somewhere creating damage. I do not believe it is an upgrade or the designers would have included one in the evolution of the engine. Luckily the engine I have doesn't noticeably gravitate oil(yet). The oil pump was meticulously refined during engine rebuilding. Maybe an approach to those engines that do wet sump would be to modify the drain system for repetitive drainings to save the threads.

If I find a thread which I think may be useful in future I turn on the “Watch” feature at the top right of all threads. Then you can easily find them in your “Watched” area. You can also opt to receive email notification if there are any updates to the thread.
 
So…

Crank case PCVs are fairly universally accepted as a good thing, and the reed valves seem to have earned a reputation of being practically maintenance free and last forever.

Why not have a reed valve anti drain valve…?

A reed valve is principally a one way air valve
Would the petal of a reed valve hold closed with the volume of oil against it?
If so would it open when the oil pump started sucking on it?
Could end up in the same situation as the spring/ball bearing type
And would it cause a restriction however small to the oil pump?
It's great that you have volunteered to give it a try Eddie keep us posted ;) ;)
 
The only bike I can think of offhand is the TRX850 and it probably has a Gerotor oil pump not something out of a Sopwith Camel.
Don't forget Honda built a bike once called the cb750
That had an oil tank I believe
But it never caught on!

The only Honda road bike I have had was the 1978 CBX but remember that CB model now.
Google shows a Gerotor oil pump used.

A twin rotor Gerotor, I wonder if they were any good.

Does draining down happen on dry sump Japanese bikes?

If not, why not?
Yes.
My TX750 did over the winter. BUT, it also had a low oil pressure warning lamp. Start it up, light went out while cranking, let it idle 10 mins, all was well.

Isn't the reason a reed valve works in a breather because it is being pushed open and pulled shut by the pressure pulses. There is very little tension on the reed against the port opening. I ran my virtual design simulator (in my head) and couldn't make a reed valve work for an oil flow wet sump solution. I'm not a Mensa member though, so I probably have some limitations.
