What docc said. The vent goes into the frame at the top. What is vented is a mixture of air pressure (from pistons moving up and down changing the volume of the area in the crankcases, plus some blow by past the piston rings) and oil that is carried in the moving air. That oil is something of a fine mist, typically. Once in the frame at the top the air slows down and the mist of oil collects and drains down to the bottom of that section of the spine frame. There you will find drain lines that route the collected oil back into the sump at the bottom. Some spine frames have 1 drain line, others have a pair. I have no idea why they would use two lines back to the sump, one should do. Meanwhile that air pressure that carried the oil into the spine frame is then vented into the airbox. Ideally it is just air at that point, no oil. But if you overfill your sump with oil you can end up with excess oil being blown into the airbox as it can overwhelm the system that is trying to remove the oil from the air that it vents.

To take that a step further, the box section spine frame serves as a separator with the liquid fraction draining through the spine into the braided line that rejoins the oil sump at the back while the vapor fraction enters the airbox to be combusted. Or just gunk up the airbox . . .

Here's something interesting. I was talking to my SIL's father a few months ago about this. He's a retired physicist thats spent a good deal of his career in the oil industry. Our long held beliefs and education of the origins of oil are quite possibly flawed. In the history of all forms of drilling for exploration nobody has ever found fossilised material below a drilling depth of 16,000 feet. So thats the maximum depth ever recorded for buried originally organic material, material that may under the correct conditions be turned into a hydrocarbon or crude oil. So why then is a large percentage of our oil derived from wells between 28 and 32,000 feet? This may be the answer and means that oil reserves are instead of being a finite resource are more like a continuing by product of the earths naturally occurring geological conditions. So oil is the product of dead forests under the influence of pressure and heat? Quite possibly not as it turns out. Saturn's larges moon Titan has also been speculated to have vast subsurface deposits of crude oil by both NASA and the European space agency after reviewing probe information. There's never been forests on Titan as the surface is a sea of Methane. https://www.intechopen.com/chapters/41889 As for the death of ICE vehicles, don't worry it ain't going to happen in my lifetime.

Ahem...do you always take the short route home on the motorbike or sometimes the leisurely, meandering longer route? Which one is more enjoyable?

People miss the point of cruise control, it's an anti fatigue device not a motorcycle or car driving/control device. Let me explain. I've been dealing with aircraft autopilots all my working life and the reason they exist is to relieve the pilot of the mental fatigue caused by hours of stick and rudder flying. There's minimal skill required on a commercial jet to hand fly the plane but it does fatigue mentally over hours of doing it. So the concept is to relieve the pilot of that low level mental fatigue that accumulates so he has more resources to focus on the important things like navigation and the upcoming landing. Keep the pilot as mentally fresh as possible. In the commercial aviation world the restrictions of flying a jet with inop autopilots is very severe indeed to the point where we never did it. We just fixed the issue. Commercial pilots don't consider the autopilot system as some sort of slur on their flying abilities which a lot of car drivers do with active cruise control. So car/bike cruise control is exactly the same concept. It's mentally draining over medium to long drives/rides keeping the vehicle on the speed limit or desired speed all the time and now with draconian speed limit tolerances and enforcement it's worse than ever. The cruise control is there to relieve the driver/rider of that mentally fatiguing process so he is free to focus on more important issues like the next corner or the road surface or surrounding riders/drivers. The best invention ever, well almost is Active cruise control. My auto cars have it. The car will hold a set speed up hill down dale apply the brakes if needed when it come up behind a slower car etc. All I need to do is worry about the surrounding drivers and dodging the road kill on the freeway and timing my lane changing. Brilliant. The difference in mental freshness on the regular 9 hour drives I do is dramatic. You get to your destination much less fatigued then before. It's not a system designed to insult the rider/drivers skill level which a lot of drivers seem to think it is but primarily an anti fatigue and therefore safety device. Other electronic aids such as lane keeping assist which is used to help mitigate inattentive drivers behind the wheel I'm not so thrilled about and I turn them off because they are generally too intrusive and not there for fatigue relief but to assist lazy bad drivers not focused on the task of driving the vehicle. Anti lock brakes are another great aid. Lets face it how many people practice their threshold braking to become or even keep proficient at it. Phil

Rats! I'm bringing my wife, so ....🤫

Aren't those the same girls who weren't there last year?

Truth be known, I am holding a room for our Chief Whip in the event he can be our honored guest at this SSR XX. At some point in the SSR past, another member promised "a handful of Cubanos ." I suppose they could stay in the room and when the innkeeper inquires about the potential improprieties, we can say, "The Dutchman flew! and the Cubanos are nowhere to be found !" Okay, okay - the actual Cubanos:

This is neat... price is 23k EUR. https://www.mini-freestyle.com/en/mini-freestyle-300-racing.html

I am thinking we should do our due diligence and pump those hydrocarbons to burn systematically in small, distributed amounts before they reach the surface in sufficient quantities to turn our atmosphere into a sea of methane . . .

I work in advertising, being concise is an art that none of you have obviously mastered.

On a long trip, particularly on straight roads like interstates, cruise comes in handy to rest your hand and wrist. Usually just for a few minutes. Many of us have throttle locks for the same purpose.

I never think about any of the modern aids when riding my bikes, new and old. It realy pissed me of the first time experiencing TC, WHAT. But with prosthesis AND, some times on the long stretches, CC gives my shoulders a break. Cheers Tom.

Thanks all for the replies. Today I learned something!

I get why someone would want cruise control on a bike, but I have no need or desire for it. I do use it in 4 wheeled vehicles, where I am just getting from point A to point B. But when I am on a bike I am there for the ride. But others, no doubt, are on their motorcycles to get from point A to point B, or maybe they just have a different idea of what "the ride" is.

May you live long and prosper 🖖 Phil I recently read a similar article on origins of oil.

The push for this agenda gains momentum every year. The push-back will continue as well thankfully. 2030 was originally 2021. Watching how various nations have recently reacted to real world energy needs gives me hope that the ICE (and coal, LNG, oil) will continue for many more years, until alternatives that actually work can overtake and replace them. "pleasure" vehicles, like most motorcycles, will be an easy target when these bans get traction.

Haha! Yep:

Soon (2025) to be paired with Pedro Acosta.... Portimao will be the reveal of what Pedro is capable of; if I am correct, this is a track where he aced it in the previous categories. Now, we can't judge Losail, since they did some testing there, so he had time to fine tune everything; (so did Marquez by the way). That being said, there is not much that has changed from 2023 with regard to Ducati Bagnaia and Martin. They have resumed where they let off.

This reminds me of something . . .

Also, be aware this vent hose can be abraded by contact with motor parts . . .

In spite of carrying various talisman on my person, and on mySport, at all times, I am not much of a believer in luck. VooDoo, sure, but not "luck" . . . "Synthetic" oil runs the gambit of claims and allowances. Good luck finding out what the actual base oil is on your motor oil of choice. There are but a very few actual Group IV/ Group V base oils. That true, full synthetic motor oils do not suffer the heat-evaporative losses of other oils might suggest a lesser load on our crankcase ventilation and less stress on this failure-prone hose. Of course, very humid environs, storage conditions, and even tuning status (too much fuel load?) all contribute to what this crankcase ventilation hose has to suffer from . . .

The man is good, but as far as blokes the play an SG goes, my favourite is this one.

I also wonder about the motor oil in use affecting the longevity. "Mineral" oils have a significant heat-driven evaporative component while true synthetics (Group IV and Group V base oils) do not. I did change my hose while fighting various oil leaks, I saved my take-off as it was not faulty. That was at about 100,000 miles/ 161,000 km.

I replaced my breather hose over the weekend. Getting the old one out was pretty easy with the tank off. Getting the new one in was a struggle. There is just not much room to get your hands in there and get the right leverage to force the hose onto the openings. But after a few choice words and a little determination I got it on securely. One thing I learned is that the MG Cycle breather hose clamp is too small for the upper attachment to the frame. It worked for the lower side to the engine but I had to use the original clamp for the upper end. https://www.mgcycle.com/index.php?main_page=product_info&cPath=71&products_id=1186 https://www.mgcycle.com/index.php?main_page=product_info&cPath=71&products_id=2785 Old vs. New

My wife and I were at this show in Oakland 2012.at the Paramount theater .front row..It was really really good..Drew Zing..the lead guitar player..( many Steely Dan songs) was fantastic..imo

After almost 2 years of searching for a good low-mileage one, my Le Mans arrived yesterday! Bone stock, and only 12k miles. Thanks to Qtip for responding to my WTB ad. Already have the carbon fiber Mistrals ready to install today!
