if I add more oil it will be blown out the breather

I thought about that.

And I thought, what about and extended filler neck? This could be an easily turned up thing that screws into the existing one.

The breather pipe (that goes to the airbox and causes oil in the airbox issues when the tank is too full), could then be taken off of this extended filler neck.

Hard to see how oil could get up into such an extended filler neck on into the airbox.

This would allow more in the tank... hopefully enough to keep the feed outlet submerged.
 
Great shot Paul . What mods have you got on your bike so far ? Relative to the The oil in air box etc.. ? Rather than look back in the threads if you could bring us up to date ? Personally I would rather deal with some oil in the air box than a oil starved engine. The way you have your feed line routed you have room for the reservoir. It could double as a side mounted oil cooler (kind of) . Or maybe you could go up the steep hill and down some other way ? (not trying to be funny) .
 
I may just mock this up on my bike to get a good clean look and just to prove it can be done . These will hold quite a bit of oil and should get you down the steep decline .
 
Sorry about resurrecting this post, but I remembered seeing it and went hunting for it. But I think this is an issue all of us have and not aware of it.
Having just installed an Oil pressure gauge in my 961, I can confirm that the oil pressure drops out completely under heavy breaking & light breaking down a hill.
My oil pressure warning light comes on now as I have it set at 1 bar and the gauge will drop back to zero, but the old warning light never previously came on prior to installing the oil pressure gauge.
I run my oil level to the top of the knurling on the stick. Something to be aware of I suppose. Maybe Norton should have pulled the oil from the front and return to the rear!

Whilst you have a closed throttle the bearings relying on the oil pressure are not too bothered by low oil pressure. The issue is the next time you open the throttle, the pump has no doubt been sucking on air and the air will take time to be pushed out of the oil galleries.

On track day cars a weir is created around the oil pick up, this is to keep a pool of oil around the pickup during fast cornering when the oil in the sump is pushed to one side, on the Norton the weir has to carry enough oil for the longest down incline.

Hi Paul - why can’t I see these pictures, any ideas? Just an annoying image icon with a Red Cross through it!:(

Check the oil pressure first . But If you find that the steep desents are starving the oil feed you can add a reservoir of oil . This would be put where the in-line filter screen is on the feed side essentially . A canister of oil in line with the filter screen . This would bridge the sarvation gaps until the canister runs out. Hopefully by then you have gotten to the end of the extreem desent . The reservoir canister would not effect the oil level in the frame oil tank and it will add capacity to the system .View attachment 8546

If your reservoir canister is big enough, it could fix the problem. You’d be effectively changing the shape of the oil tank.

The filter above the pump had better be just a gauze strainer and not something that could restrict the feed to the pump.
 
Yes , agreed , it is the Norton OEM strainer. The reservoir ideally should be shaped to maximize the available space. It can also go further back to above swingarm pivot area just above behind the regulator. This problem does not plague most owners , if it did I would have resolved it for myself already. However , If you look at the pictures of my bike you will see a half hearted attempt to demonstrate this reservoir idea. I used a billet aluminum fuel filter body with internal filter removed. It would need to be much larger to bridge the 18% , 1.5 mile grade he is dealing with.
