Author Topic: Oil gauge with idiot light? (Read 4939 times)

I am looking for a oil gauge with a external link for a light but can't seem to find anything I want to install the sender where the oil switch is and mount the gauge between the gauges with the factory oil light run by the pressure gauge. Has anyone seen something like this?

I recon this would do the trick, it would allow you to retain the stock light and have a gauge too. Mount the sender where the gauge normally screws in

I had to laugh at why they say this is a good thing:
"Most motorcycles do not come with a way to monitor your oil pressure. They simply come with an “idiot light” that tells you when it’s too late and the damage has been done. Over the past several years we’ve seen a few parts on the market that try to remedy the problem, but still put the gauge in a position that is unfavorable, and sometimes dangerous. So, we decided it was time to just make our first part. A logical, affordable, custom oil pressure gauge adapter that will really set your ride apart."
Then look where they mount the gauge. I don't see how they solved the issue at all.

I noticed the oil pressure was dropping, just before I ran head on into that truck.

This simple hydraulic "T" will do the same for $2 instead of $45:

But "T" will not set your ride apart.

And there are some that say that looking at oil pressure gauge next to your foot is distraction. What do you do with jbwebster, stick your head under the fuel tank to check it out? Or ask the guy next to you at the traffic light to see what's pumping?

The whole reason for an idiot light is because not many people monitor oil pressure while riding or driving.

+1. Over the years I had quite some narrow escapes. All had to do with having my eyes not on the road and every time I was taken by surprise how quick the situation had changed.

I install a oil gauge in almost every vehicle in a easy to see place as they give me a heads up. This is important with my obsession with turbos or when I use my truck for towing both of which put a lot of strain on a engine. I have one on the dash of my xvz1300 sidecar because of the extra weight. I guess its just a habit that I have at this point and I just hate having a useless light on the dash that's why I wanted to keep the use of the light

It was never stated whether we are referring to a pressure gauge or a temp gauge.

Sorry pressure guage is what I am looking for

Just out of curiosity what does a CB750 run for oil pressure?
My Sportster only runs 3-7psi at anything less than 20mph and a maximum of 10-14 under normal riding conditions.

a hell of a lot more than that

60 or more cold ..its plain bearing and your Sporty is rollers, hence the difference.
I am notvsure tye pressure switch hole is NPT..., I think close but different.

While I agree with the "eyes on the road" idea in theory, the real world facts of riding 40+year old and/or modified versions of same bikes make minding both oil temperature AND pressure a most prudent pursuit. And to boot, a good gauge is a lot more interpretive of changing conditions than a light whose best use is to tell you your engine isn't running....

Joker Machine makes one for the CB750. All you do is unscrew the oil galley plug above the points cover, apply some thread sealer on this and screw it in. Quick and easy.

I use the Joker "enhanced" oil gauge and mount. Same attachment point, but more flexible to use. Anyway...

I had one mounted so that it appeared in the opening between gauges on a Unicorn style fork upper tree clamp. That's the only place, or the handlebar, that is totally appropriate for monitoring. And if you've got it right there in your face, you don't need the light.

The ones on the motor are not so much for looking at while riding, but more for looking at start up after a rebuild and as a toy after that. I mean, if you've got pressure to start with, you've got pressure at the end.

Has any one ever suffered an oil pressure failure on a CB750 on the road?

That's a bait question, eh?

754 · « **Reply #15 on:** November 27, 2015, 08:55:27 PM »

Not oil pressure I think..but rod bearing failure... Wish I had a guage... May have not run it all the way home.. 350 miles..

On the bikes I have had the guage on , i check almost daily on startup, and while riding on really hot days. When the oil return tube broke off inside my custom oiltank, all the oil ran to the sump.. When on the sidestand no oil pressure, when I stood it up I had pressure...... Because of the guage I became aware of the problem... Finding the problem took a long time..

I check the oil pressure at start, traffic lights and before I shut her off. In my experience fully warmed engine idles at 20psi with 20W50 oil.

When riding, the oil pressure is too much function of rpms to look at it anyway. Still see no harm at quick glance down, it is faster than looking over your shoulder - and everybody does that.

Mantree · « **Reply #17 on:** November 28, 2015, 03:57:31 PM »

Maby I will just do a guadge and replace the oil light with a turn signal light and have a left and right signal warning that will get rid of the non functional light on the dash

In my experience, if your losing oil pressure the damage has already started and you'll be lucky if you happen to be looking at the gauge when it starts. Sometimes the loss is immediate and thats when the idiot light is important, gives you notice to shut down before you bust rod or something causing more expensive damage

spiritof67 · « **Reply #19 on:** December 06, 2015, 09:13:43 PM »

There were quite a few "period" oil pressure gauges that mounted up at the top triple clamp...shouldn't be too hard to find one.I have at least two of 'em somewhere...SW gauges at that,or there was a VDO kit with a whole handful of nice brass adapters....

Deltarider · « **Reply #20 on:** December 06, 2015, 11:43:35 PM »

Here we had a brand Racimex, but I have seen similar that had the names VDO and Honda in their dials. I do not know whether these were genuine VDO or Honda products or counterfeit. They looked very plastic and I’ve not seen many of them. From an esthetic point of view one can say that the two gauges ‘echoed’ somewhat the original layout (speedo and tacho) but, if you’d add a voltmeter that effect was spoiled. Good thing was that they were in the view of the rider. BTW, I wouldn't worry about the oil pressure and keep it simple. Temperature gauge could be useful when you ride the bike hard, real hard, but I personally haven't witnessed this practice in US ever.

Is an oil pressure gauge really needed on a CB?
The red lamp will indicate if there is a problem if it take longer time as usual to be switch off when starting the bike.
OK, if there is an oil cooler mounted with hoses that can start to leak a lot, pressure will be really bad, tire grip too

The typical oil related problem that can happen on a CB750 is blocked oil feed to cam. Will an Oil pressure gauge alarm for this?
I have checked the oil level on my Cb750 rather often when bike is warm just for sure. At least once a week.

Never an oil fail on my bike, only too cheap oil or wrong oil (car oil)

Edit spelling, my fingers hit rate on keybpoard can be better

Deltarider · « **Reply #22 on:** December 07, 2015, 01:56:09 AM »

I agree wit Pewe. I have yet to meet the first CB owner that experienced a damage that a pressure gauge could have prevented whereas I wouldn't underestimate the possibility of a leaking sender or connection... Hate to think of it and I'd keep it simple.

Oil gauge gives a piece of mind, but you are right, it is not necessary.

Going down from Skyline drive, hill about 5 miles, full of turns with 35mph speed limit I usually find a neutral between 5 and 4 and just glide. Quite interesting - ok for me at least

- to see the oil pressure increase with the engine cooling down.

Idiot lights really do do much. It would be super dead simple to incorporate a proper oil pressure gauge that you could put up with your speedometer.
