Ronnierockets anti wet sumping device
« on: 06.06. 2009 17:19 »
Ronnirerockets, On your fantastic anti wet sumping device,where did you get the gas tap from and what size is it please. did you use the original elbow and fitting(nut) on the oil tank and did you fit it on the flow or return side? I hope you don't mind me pinching this brilliant idea, regards Tony.

Tone... There is a very good selection of gas taps etc in B&Q! There must be a large store in Brighton somewhere, they even have a good selection of reducers etc. BUT if its for making up a wet sumping device... I dont wanna know!  *roll*

Thanks LJ, What have you got against the anti wet device that ronnierockets devised? I would have thought with the kill switch on it, it will be fooloroof. Cheers Tony.

Well... my opinion is that we have these old bikes for our enjoyment which should mean that we are keen to regularly start them up and ride them, if not then why hang on to them?  *dunno2*

If wet sumping is bad and occurs in a very few days then there must be problems in the engine that need sorting. The fitting of a wet sump device is not a good subsitute they should never be needed. Of course a wet sumping of some degree does occur and I believe this is good as it means a very good lublication of parts down there below, the first initial starting is supposed to be the most wearing/stressful on an engine until circulation gets going, so I'm told. Of course starting a very heavily sumped bike does mean a risk of blowing gaskets and may cause other problems. (remember I'm not an engineer and other more experienced guys will advise you better)

Why not purchase one of those very good SRM sump plates with a magnetic drain screw that we have seen discussed here only recently? So easy to drain and return to tank with absolutely NO risks involved! I've read of too many 'bangs' due to oil starvation!  *eek* Ronnie's device does seem good but I'd rather save myself of all that effort and go for a simplier alternative.

On the odd occasion a bike, usually my red A10, has wet sumped heavily, even with straight 50 in, the bike has been fairly easy to start, probably because its worn. But my other A10, the blue one does not wet sump at all, this one having castrol R40 in. The Star Twin I am still running in and has Halfords classic 20/50 in and is fairly thin so will sump easily, it has been off the road for the last ten weeks due to the petrol tank at the chromers. But it started easily.

Thanks LJ, I have one of those sump covers, After talking to you I am going to have a rethink. Perhaps it might be worth having a look at the oil pump, cheers Tony.

I was wondering since the subject has come up again, do we as a group have experience or confidence in those in line anti sumping jobbies ?

hi dont put an anti wet sumping device on your bike if it fails your engine will
be badly dameged go for the sump plate kit with drain bolt on
a much safer device even srm say dont use them just drain the oil
out ove the sump put back in tank you could even cheak it each time you
drain it for particales there is a sump kit srm do with a drain plug on wich also
has a magnet on which will cach the particales on it it a much safer option

Reckon Brian got it right when he implied, under 'Anti-wet-sumping - other fixes' that there's maybe no such thing as a fool-proof tap with fool-proof ignition earth. All it needs is the carbon brush to stick in the mag end-cap, the wire to break off . . . etc.

But, that said, I've been running taps in the feedlines of machines of another more incontinent marque for a while. AMC twins are quite notorious. I do use taps - B&Q taps one size bigger than are suitable for fuel lines - with ignition cut-outs attached. There's a 'pre-flight routine' which mustn't vary; there's a label on the ignition lever that says 'OIL?'; there's a kill button on the handlebar which is also supposed to remind me - if it doesn't stop the engine when it's running, then the switch at the oil tap won't stop it starting either - as they both run  off the same brush and spring.
So far so good.
Some wag elsewhere suggested - not a joke - that there should also be a mechanical thing on the kickstart somewhere/somehow which pulls the tap open as a last resort. Not a bad idea, but a bit difficult to contrive. How long and rigid IS a piece of string?

The consequences of cock-up are unmentionably horrific, which is why, above all, the pre-flight routine is important.

I haven't bothered with the A as it doesn't offend too badly too often. I was thinking about it . . . but I'm not going there.

yes you can put loads ove warnings on your bike to remind
you but if something goes wrong your engine might end up
as a project and a big bill to fix

Not getting into any arguments here, this is down to personal choice and what you feel happy with but (theres always a but) I would still like anyone who has had an engine damaged due to a definte and confirmed anti wet sumping valve to say so.
BriTie must have supplied lots of these things and are still in business (I think) it would not take many failures of these devices to ruin a trader given the small margins they probably work to.

There you go another day started with me at odds with the world - ah whats new. *doh*

I will let you know if the anti wetsump valve on my Super Rocket fails. It has been on a couple of years now and covered a few thousand miles and all is ok, I know of others who have had them fitted for years with no problems.
Yes Britie (polly) is still in business even though he gets more grumpy as the years go by ONLY JOKING Polly

Here is my Wet Sump valve, needless to say I removed it soon after bringing the bike into my ownership. This was on my Blue A10 the bike in my fleet that least wet sumps!

Now these devices go for around £30 quid on Ebay and they seem to go like hot cakes because of the inconvienience of wet sumping. The instructions are clear about fitting the device the correct way round and also mention of catastrophic engine damage if fitted incorrectly. Looking at the device it would be easy to fit wrongly, I measured it up and the differencies between the end pipe lengths were only a millimeter or two. To the unaided eye there looks to be no difference in length at all. How many of us rush to open the packaging of a new goodie and fit it without carefully following instructions? (My feeble hand is raised!)

Anyway this valve needs a good home, It's available to anyone who wants it for a reasonable offer! On the basis that its not fitted to an A10! of course  ;)

correct me if im wrong but to operate a valve do you need suction and arnt bsa oil pumps
gravity fead  it only takes some particals ove metel in the oil to stop the valve working then
its game set and match end ove the road

the A10 swing arm valve screws into the crankcase the type you have would be suitable for a plunger A10 so bring it to the Wicksteed weekend and I will have it
