I think 4-5 Lb is pretty close to the mark, I think thats pretty much standard on most auto oil pressure switches.
I think if it was 15-20lb then you would probably not be game to ride your bike.

Really? 15-20lb is much closer to the point you should start worrying about your oil pressure. If the pressure has dropped to a permanent 4-5lb something is definitely wrong way before you got informed by your warning light. My point is that an oil pressure switch doesn't say much (just that there is 4-5lb oil pressure and hopefully more!) so if you want usefull oil pressure information the only right thing to do is fit an oil pressure gauge :!:

its just to warn you of a sudden loss of oil pressure! why would you not want it? even if you have an oil pressure guage fitted you dont ride along stairing at it! i have a pressure guage on my t160 i also have the standard oil pressure light its a good setup , just about every car has a low oil pressure warning light it works well

I see some strange thoughts posted regarding oil pressure of Nortons. There are those who would never buy a car/truck without oil pressure monitoring yet insist an oil pressure gauge has no place on a Norton. Must be because of Norton's fabled reliability.

Sounds like wanting to fit a warning light to inform you your warning lights stopped functioning :mrgreen:

jesus christ mate thats stooping low editing my quote to make it sound stupid!!, ok then you are correct everybody throughout the world should remove their low oil pressure warning lights and fit oil pressure gages to every vehicle

Gee....I was just kidding :?
 
Received low warning pressure switch today many thanks ,baz
 
I've been running and oil pressure gauge on my Nortons since the late 70s when George Gjonovich from HPI gave me one he made for his race bikes. Everyone has an opinion on whether it's needed or not, I don't care I like them so I use them. My current 850 has one because it had one of George's on it when I bought it. I may not have put one on but I like it so I keep it. Frankly I think The idiot light idea is useless but if someone wants one then that's great use it. It's silly to argue because it's like one man's want over another man's want. I like having the gauge to tell me the condition of my oil pressure cold and hot but honestly if I was cruising down the freeway at 90 miles an hour and lost oil pressure the damage would be done before I noticed the gauge or an idiot light.

Actually, a Commando will run quite aways with no oil in the tank. I have first hand experience with this. A disgruntled wife, who later became an ex, decided to put a stop to my ramblings with my Norton. An idiot light will get your immediate attention, whereas a zero reading on a gauge probably won't. I agree that an oil pressure gauge will tell you a lot of things besides the pressure of the oil.
 
Yes, you can do 7 miles before it starts squeaking. And then you may do another 2000 miles before it blows up. So why not put an oil pressure warning light on your bike, then you may only go 1 km with it glaring in your face.

Yesterday, I saw on British TV on an Antique program called Flog It a RR Merlin engine oil pressure plate (used in conjunction with an oil pressure gauge) from a Hurricane that crashed in the Egyptian dessert during WW2 being sold. The various oil pressures that were on there for the pilot to check whilst running in those hot conditions would confuse the average layman
 
I can attest to the fact that a Commando can do quite some distance with no oil...
In the '80s I used to be a dispatch rider running news film around London for the BBC (pre internet days, you had to get it back in time for the bulletin)
I had bought an 850 MK3 and used it every day, and in fact still have it. The previous owner had fitted a shut off valve to the feed side, which I had never bothered using for obvious reasons. One day I parked up at our office in Lime Grove, Shepherds bush, and for some unknown reason, flicked the valve to off...No obvious reason.
I got an urgent job in the West End to pick up News film and rush it back to TV centre to be editted for the evening news. Jumped on my bike, roared off and onto the Westway, and elevated Motorway into the West End, After a while I thought hmm, the engine is sounding a bit clattery and noisy... looked down and oops!
Flicked it back open, engine calmed and cooled, noise went away...
The valve was removed ASAP, but it was a good 10- 15 minutes on a motorway, and we weren't slow then.
 
That's what happened to me. That's how i know when the squeak started, and that I had done the Kaikoura to little Wanganui rally and back before the 2 nuts on one con rod started to come loose. By stopping in time I saved a big mess. Thought that would never happen to me. How wrong I was. The bike now has an ignition cut out on the valve, and I cable tied the valve open before the last rally to prevent any mishaps. Bike has gone well since the rebuild and no oil leaks. Just did 3145 miles ape Reinga to Bluff and back via the Norton Rally in Dunedin.If I had an oil pressure warning light on the bike I maight not have stuffed my engine.

Knowing if you have oil pressure either with a gauge or light is a good thing and surely we all agree on that. So as far as i can see here the point is would you notice the light or gauge telling you bad news before its to late. My answer to drawing your attention to this is take a power feed from the side light as i start my bike (an cars) then turn lights on once the engine is running. This feed would then be wired with a relay to the oil pressure switch and the horn. If oil pressure is lost the horn would sound an get my attention.
Yes i might not turn the lights on just that once or the relay or fuse might just that once fail. But we all (am guessing could be wrong) have other cars bikes etc. an they have oil pressure warning of some kind do we worry about them? On my car its the warning noise that makes me look down at the dash to see whats wrong so why not the bike? Just needs to be a louder noise to be heard over exhaust :lol:
 
I did the same on my mk2a ,on the way to work one day I had forgotten to turn my oil tap on , the bike did 8 miles before it started to rattle and squeak ,I quickly turned the tap on and pulled over luckily I got away with it because it quietened down and after a couple of minutes I carried on with the bike running fine again, I never thought I'd forget that tap but I did!! And removed it shortly after
 
a year ago a guy told about his way to stop wetsumping in the roadholder magazin. he is doing it for years.
he uses some sort of cramp like this

https://www.amazon.de/Schnellspannzwing ... B009VY1EHY

to squeece the rubber oil line. you will remember loosen this device because of its size

good idea, but i am a little concerned about my oil line.
 
I personally don't see a need for it. I can tell by the sound of my engine if it's getting oil, especially the top end.
But hey, if somebody thinks it's a good idea then I say go for it.
 
If you run your engine without oil, you will do some damage, but it may not be obvious for a while. When my 2 big end nuts came loose, I didn't twig to why it happened until I read somewhere of the opinion of a mechanic that the slight vibration caused by extra big end clearance, can and will cause the big end nuts to vibrate loose. That's what caused mine to come loose. My lower end had never been worked on by me, and if it had been, the nuts would have been loctited in place and may never have come loose. There was less that 1/4 thou wear on the big end journals and no scuffing so it went back together with new bearings, and a reworked rod.

Those using a tap in the input to the oil pump fall into two categories, those who have destroyed the engine due to the tap being closed and those who will destroy the engine due to the tap being closed. Never, never put anything inline between the oil tank and oil pump.
 
I bought a 350 wideline affair about 5 years ago with an on off tap on the oil line , got shot of it ASAP and fitted an RGM anti wet sump valve and have had one on my 70 bike for three years. never a problem but when I had the oil pipe disconected from the bike there was oil on the bench that had ran out the valve overnight so I assumed that it it was not 100% oil tight. A pressure light as well as the anti wet sump do Dah seems to be a good combo .
I would like to have fitted a commoz sump breather but it was not possible . My 69 bike does not wet sump but a sensor light might be fitted yet on it.

The only problem I have ever had with inline non return valves was one on a C15 fitted in the crankcase AFTER the pump, supposedly the one that should never go wrong, well it did but as I had just rebuilt the engine and fitted clear oil lines I saw it fail before damage to the engine. The oil would flow initially and then stop followed by the flow reversing and bubbles coming out of the oil feed line to the engine, 2 oil pumps, clearing out the engine oilways including the crank all failed until I opened up the inline valve and took put the ball and spring and ran without.
