Anti wet sumping valve, who's got one ?.

Which make ?, is it doing what you'd hope ?.

Has anyone tried one of these ?: [Broken Link Removed]

My bike is wet sumping, this bit that really shits me is when the engine oil flows across into the chain case and makes the clutch slip.

So either fit a wet sumping valve or replacing the oil pump might fix the problem ( I did pull the pump down and it was tight and functional ).

Suggestions ?.
 
I've got an anti wet sumping valve. Even with the MKIII timing cover, leave it set long enough and it will fill up. I don't trust those automatic thing-a-ma-jigs, but i do trust me. Oil valve, gas valve, ignition, lift off.

Also, the seal on the crank is sometimes the issue. The inner primary cover mounting bolts, particularly the one at 5 o'clock, are more prone to leak than the crank seal. Goop this one up and see how it goes.

 
That's what I wanted to do, but my dad fears that we will forget to turn it on before a ride. That would be disasterous!
 
In case you missed my edit.....

Thanks gents,

I did goop up the bolts, the crank seal is new.

From what I understand the crank seal will not stop oil from flowing across whilst parked and wet sumping, it will stop the general oil splash during riding.

Failing, sticky little bullcrap valves that hinder flow ( even if slightly) can also be disasterious
Put a little sticker somewhere obvious (rear view mirror, or a reverse tattoo across your forhead, but then again you would still have to look in the mirror) for training. Once a habit, it's for ever. Accept it as a way of Norton life. Or spin the wheel.
 
That's what

I've been thinking about that... Not the tattoo but the sticker or something. Even as far as a wire or string or something that can attach to the fuel tap and valve so I can't turn on the fuel without the oil first. If it would look unnoticeable or okay I might try it.

Many are turned off by the plumbing hanging on the bike (Hobot) but few notice as I fly by. If it's a trailer queen you won't need oil period. I work so I don't get out as often as some yet the valve is second nature now. When looking at vintage units, I mean like 1910 to 1930, it was just part of the deal. Once you become adjusted, you never worry about wet sump again. There are chromed brass units that are more attractive. I think when it come down to nitty gritty, we're spoiled. Wet sumping has always been and will alway be associated with dry sump motorcycles.
 
I'm not entirely worried about the look, I might be able to find a spot where it's not seen. I'll look around and see what I can find...that is if I put one on.
 
You could put a safety cord from the valve to your ignistion switch so you can't put your key in till you have turned it on and remove the safety cord, just a idea, but I have owned my Norton for 36 years now and it has never wet sumped as its is ridden nealy every day.

I ride my bike regularly but it might have to sit for a week or two or three while I'm pre-occupied with work or something. I have started it with a quart or more in the sump and never had any problems. I ride easy until it's thoroughly warmed up but nobody has ever explained to me how much wet-sumping will cause a problem...Or maybe I'm just lucky I've never blown a seal? No way I'd ever trust an anti-wet sumping valve, or myself to open up a manual valve.
 
I have one. I got it from Matt Rambow at CNW over one year ago.

It is an inline valve and it works perfectly.

Perfectly, thank you.
 
There was a thread here maybe a year ago, geo46er put a switch on the handle so you had to open the valve so the ignition would work. post66203.html?hilit=geo46er#p66203 Pretty simple. Mine wet sumps in about 2 days and the oil tank is completely empty, but I just start it up and the oil comes back. Haven't had any problems with oil getting into other cavities like the primary so I haven't been worrying about it. I did the same 40 years ago.

I think there have been a couple of others that do the same with a different switch, you could put a microswitch to contact the handle too.

THERE'S ALWAYS A BAD STORY FOR A GOOD STORY.
Procedure is procedure.
I know a guy ( a man of the cloth actually) lovely bloke. Bought a 75 850. Waited 35 years.
Test rode it, paid the deposit, went back with the cash, Unfortunately only the sellers wife was home.
Guess what. Didn't know about the tap in the oil line.
Didn't make it far down the road. Had to trailer his new bike home.
Being the type of guy that he is, I doubt the original owner even knows what happened.
Absolutely 100% true story.
Complete rebuld now, with valve fitted.
Morell to the story i guess is make sure every one knows about the tap.
If I were fitting one or the other, it would be a tap, at this stage nothing.
So what's it gonna be Josh.......

I have had the velocette-style one on my bike for a couple of years now, without any problems. When I set it up, I added an oil pressure gauge, just for peace of mind. So far, so good.

Split at the seam, from nothing but the movement of the oil line. And no, I did not have it in a bend. I was lucky enough to discover it when the bike was "on the lift" rather than "on the road". Installed a sump plug with an integral drain plug and park her on compression. After that, not much to drain what little seeps into the crank anyway///

Well, if my dad confirms, it may end up on the bike. that actually seems like a great home-made fix.
