Hi,

"I'm fairly (= almost totally) ignorant about anti-wet sump valves. I've just read a couple of threads and it seems to create strong opinions. How do I tell if I've got one? Is it the metal thing in the oil pipe just above the gearbox? Can I tell if it's one of the "safe" ones with the weak spring? The majority verdict seems to be that wet sumping is less of a problem than the valve."

I'm nervous even mentioning this particular topic :mrgreen:

I think the wet-sump situation falls into 3 camps:

1. It's not a problem just ride the bike more often and don't worry about it. Just take it easy for the first 15-20mins

2. It can cause a problem, blowing seals, so just drain the sump before you head off & pour back into the tank.

3. Use a valve or petcock to stop the flow of oil into the sump

I fall into camp 2, Norton ownership can sometimes be difficult enough, why add another potential complication. When I first got my bike I got SRM in Wales to look over the bike & give it a service etc. They refused to give the bike back to me with the anti-wet sump valve still installed, so was their conviction that they can cause major problems.

Take a close up pic of the item plumbed into your oil line and post it here, I'd say it's an anti-wet sump valve, at the very least you should know if you have one as most/all? need to be primed after an oil change.

The main thing is get out on your Norton as much as possible and enjoy

IMO, the only thing that should be between the oil tank and oil pump is an oil line. If you are concerned about wet sumping, a check valve at the pump output and "O" rings to seal the pump shafts will get the job done and you'll never worry about oil starvation. AMR does a great job with this.

I have fallen from #2 to #3, but I'm thinking about the AMR this winter. At least I don't have the excuse not to ride because the sump is full, plus now it hardly leaks at all. I haven't seen a drip for at least 3 weeks and the center stand is oil free.
