I don't think it's necessary to hook up a gauge if one wanted to monitor oil pressure. There's already a oil pressure sending unit that provides oil pressure in real time. You can read it with the dealer tool / OBDStar.

thanks, i assumed the stock unit was just a pass/fail kinda limit switch...not something with readout...ill do some more digging
My OBDstar for my V4SF euro 4 does not seem to have this ability. I too thought that it was a dummy switch. The problem with the regular automotive gauges is the cheap ones only go to 60 lbs. Gauge and lines probably less than $50 from summit. You'd need to measure the threads on the current sender (probably 1/8 pipe) and buy the appropriate fitting to go to 1/8 tube. The clowncar has about 40 psi at idle. I have no idea if this is good or bad (hasn't grenaded yet). This does give me a reference for the next time I check. These motors run high oil pressures, when building V-8's the rule of thumb was 10 PSI per 1000 rpm. You can't really measure high rpm oil pressure anyway unless the motor is under load like you're lying on the tank WFO in 5th at 15,000. Not the best time to be looking at oil pressure.

When I get home I'll check again but I'm pretty certain it gives a readout. I don't think it was in PSI.

Further, with the OBDStar, you can record any sensor value so you wouldn't have to look at it. You could log RPM and oil pressure, etc.

ETA: it may be a switch. I found the p/n and a spec which is 0.15-0.4 BAR. Being that low, 2-6 PSI I think it’s tripping when the system is pressurized.

I wonder if this is lower due to the wide spread use of electronics. When I lived in the California bay area (left in early 2000's) there were about 4 to 6 sportbike deaths a year on highway 84 alone which goes from Alice's restaurant to the coast (fine twisty road). So, it ended up over patrolled.
I’ve ridden the roads you’re talking about many times. Ducati once had a great event at La Honda just down the road from Alice’s. For those readers from other parts of the world, Alice’s is the premier San Francisco / Bay Area motorcycle hangout, similar to the Rock Store in LA. The area also known as the Skyline Drive. Twisty roads everywhere, but extremely dangerous on weekends. I’ve seen so many ugly motorcycle accidents around Alice’s that I don’t ride there very often. But on the weekends, it’s a blast… until it isn’t.
Let me clarify my original point about motorcycle deaths and serious injuries. The riders reading this forum are not your typical motorcyclist. Most of us have been riding a long time and know what we’re getting into. But for new riders to become old riders, they need to make it through what can be a tough learning curve. Our sport is under threat from many directions. Fewer people are riding today. For our sport to continue, more of the fewer young riders need to gain enough experience so they can afford the types of motorcycles we like. If there’s not enough riders, motorcycle manufacturers die out. Which I think we can all see is currently a problem.
I see the YouTube videos glorifying completely idiotic riders. While I can still remember being young and stupid, I wasn’t as stupid as many of these guys. I doubt many of these guys will ever make it to the point where they would participate in this forum. We’ve all known guys who quit after one minor crash. Some should quit, they don’t have the right mojo or whatever you want to call it. As we know, fast motorcycles don’t suffer fools for very long. My intent was to stress the importance of maintenance, and how it can help prevent some accidents. I’m at the age where I feel like paying back the sport and helping new riders understand the value of maintaining their motorcycle.
As you know, after some accidents you can’t tell what happened? Did some sort of fluid leak onto the rear tire? that contributed to the crash? I always assumed anyone riding a motorcycle understood how they worked. That was until a friend who didn’t ride asked me to help his son work on his motorcycle. The poor kid didn’t know anything. The point being, I’m more inclined to help newer riders with the learning curve. Instead of quibbling about some statistic, toss in some nugget of knowledge you think might help a fellow rider with less experience.
Trust me on this statistic, a day in your garage is better than a day in the ICU. And a day at Alice’s is the best of all.
 
Don't want to derail the topic, but quick question. To all the oil experts in here, where do you send your oil to be analyzed? I have used Blackstone once and that is it. They seemed good but I'm far from an oil expert. Just wondering if there is a better option? Also just got an email from Blackstone saying they are increasing their price to $40/sample next month. Really enjoy the info in this thread! Thanks!
 
I dumped my 500mile redline 15w-50 this weekend, took 300cc sample and sent off to Speed D.

The flacks and gold i noted in the pervious dump were no where to be found, happy about that!
My super mag on the drain plug also had Zero debris for the very first time, happy about that too.

Will share report once i have it from speed. It was 514 very hard miles, I feel like my weekend blast days are on par with a single track day use/rpm wise..

Will be interesting to see how long this oil is good for...nice to finally start having some data for once too

This is great , i will be doing the same with the redline but not until March or April . Its good to have your data since i have to wait. Also dont forget there is still some 300v in that crankcase so run the redline for a while and keep recording data. I would say you will be @ 100% redline oil in that engine after 2x changes from the 300v dump.

I have a really good feeling this oil will not sheer. Did you dump and sample the redline oil warm or cold?

Also how did the engine feel? Clutch feel? Did the bike run cooler as well? All data you can provide is helpful.

Ive done about 20 samples with blackstone and 8 with speediagnostix , i recently sent out 3x virgin samples to each and blackstone had major discrepancies on the additive side. Ive since switched to speediagnostix for precision of data.

This my 3x flush with Redline, so i'm pretty sure the 300v is all gone...but cant say for sure of course...what i can say is there is no more green tint.

i drove the bike 30-40miles, got it hot with fans cycling on/off, drove home and dumped the oil into pan <5min after i shut off the motor (did my drive with lower belly pan removed to make this easier and faster when i got back), and I waited 4 seconds before i put the sample bottle in the stream.

Then i put the oil from pan back into my bike, and added 400cc of new redline to make up for the 300cc i pulled out and figured 100cc worth of loss in my pan and container i poured the oil back into the bike with.

I suspect the sheen and flakes in the oil pan after 500miles of 300V was clutch material as i did have some grabby clutch issues with the 300v, but that is totally gone now with the redline oil. Also there was no sheen or flakes at all after 514miles on the Redline.

Impossible to say if engine ran any cooler, it was always 3 or 4 bars, and the texas temps very wildly this time of year. The 30-40miles recently for the SpeedD sample ambients were 50F...but a couple months ago it was 100F.

Hope to get speedD sample back this week, will share as soon as i do!

Thanks as always @NYCV4S
