Although I (still) don't know how to use this, I'll throw it into the ring. We have it at work, and the colleague that uses it most seems to like it. Another colleague, only been there 2 years or so, did a Masters in Documentary Film Production. I gather she learned to use it whilst at Uni, so it's not just us using it. There is a free version, but I don't know what the difference between the free and the sold version is. Even so, the sold version apparently only costs about $300,-. Have a look at it. Maybe it is a solution. https://www.blackmagicdesign.com/products/davinciresolve The blurb: One thing: the computer needs a bit of power, or it will be really, really slow. PS: I gather that the software is cheap because Davinci earns its money on cameras and such, and things like specialised controllers for the program. The want people using the software to keep them in the "ecosystem", so it is fairly cheap for the small-time user.

Book it up to environmental protection. The air that comes out of the crankcase is heavy with oil vapour. It's better for the environment if the re-condensed oil goes back into the motor.

@audiomickI'm very clear on why the pressure needs to be handled, just don't understand why a line that is connected directly to the sump has to be part of it. My older Ducatis just had a black rubber hose that came from the top of the crankcase and was strapped to the frame under the seat. Maybe that system is ancient now, but it worked very simply. Why the oil line is part of this system now is what I question. I'll stop beating a dead horse.

It would be a bit pointless if it were a closed system. It is there to compensate for the change in volume in the crankcase as the pistons go up and down. This change in volume is not all that far short of the displacement of the engine. A closed system would increase the total crankcase volume, thereby reducing the relative change in volume, but would not be able to compensate for the change. For that, air has to be able to escape on the downstroke, and get back in on the upstroke.

those are correct, but I have plates and pins in the mail that should be the correct ones. We'll see.

I have two pins 20mm on the thread dia. , 17mm on the pivot pin and one nut w/the hex being 30mm on the o.d. of the hex

Sure was. Dry as a bone now.

The interesting part came towards the end of the video, and has nothing to do with the RG 500.

Well, I had never dug into where those expansion chambers came about. All I know, is that I had a Gitane Testi when I was 14 years old, and I purchased the expansion chamber sold by Motori Minarelli for my 49.9cc engine. I knew the reason and the principle about it, but I never imagined it came from Germany.

@activpop, was your leak at the washer, #20, in that diagram?

I've only replaced my vent hose once, but it really wasn't the source of my leak problems. Part of my issues was the #15 gasket for the oil pipe that the hose attaches to. (Notably, oil leak from this gasket appears at the 'weep hole" at the bottom of the clutch housing.)

Interesting. So it is not truly a closed system, it has an open line to the airbox. So when the engine is running, especially at higher rpms, there is negative pressure pulling out of the spine. So I'm not sure if that helps or hurts this condition of possibly getting oil contaminated, simply because there is an oil line open to the spine. Does oil ever get pulled up there? IDK. I'm no engineer. All this looking around though has me finding a crack in the rubber tube coming up from the engine. Time to visit the old thread on replacing it. How many tubes have you replaced on your high mileage Sport @docc?

Could have stuck to history without the political commentary, but fundamentally good. Oh, and "The engines are identical" is at best misleading, and at worst, well, misrepresentation. Anybody who's ridden one knows it's not 170 horsepower, doesn't come on like a light switch- in fact, the powerband is much less abrupt than a Kawasaki Triple. Even if every part number in the engine is the same, the pipes and the porting make all the meaningful difference. On most 2-strokes, an hour by a professional and a tailored pipe can add 10-50% to any 2-stroke, depending on era and state of tune.

One of the difficulties assessing the system is that the vapor recovery (which would include water vapor) is not on the parts diagram for the ventilation system ("oil pump"), but on the "air filter" page (16-20) . . .

This is correct, crankcase ventilation/oil vapor travel up from the back of the engine through the nefarious double-bend rubber hose under the frame to the bottom of the frame spine behind the headstock. The frame cavity acts as a separator with the gaseous fraction following the path @gstallons describes (a hose visible from the fitting on top of the frame spine, behind the headstock/ in front of the tank) to the airbox, and the liquid fraction draining down through the frame cavity to the return line and back into the sump. Ideally, adequate running temperatures will evaporate the water before it drains back into the sump. Less than ideal would be short operating times, very wet environs, and long storage periods. Also, oil selection plays a part. Pure synthetics (true ester base oils) have close to zero evaporation loss from heat and aid the efficiency of a complex, closed loop, crankcase ventilation system like ours.

Hence my previous concern about a risk of contaminating the oil. It seems like it is a closed loop system, where the give and take changes in pressure take place in a rectangular steel tube. Am I seeing this right?

@gstallons, take another look. On my two Sports in the shop the rubber breather hose connects from the upper rear of the engine to the underside of the spine frame at the front of the tank location. The metal braided tube at the rear of the sump land on the side of the spine approx mid tank. Pg 75 of the parts catalog shows this. Check it out and let me know what you think.

Since we touched on sound/video considerations I thought I'd start a conversation specifically about that. I had a GoPro a few years ago, video quality was good. Sound was shyte. Video editing software was not intuitive, data storage requirement was enormous- in the end, just gave the camera away. Got Innovv F&R cams on the 'Sport; video quality nearly as good, audio also shyte (neither had external mic port) direct-to-card recording at least made getting it into the PC easier. Editing software was generic, don't recall what it was. Still, not easy to use, add/subtract sound etc. So what's the easy answer? I see the cameras most common to vloggers, they still use GoPro but may have multiple brands (360 etc.) What are they using to put it all together? Ushuaia has been calling

The answer is obvious once you see it- those people can't afford $1k-$15k to have their air conditioning repaired. If I was to open a business here in South Florida, it would likely be A/C service.

Found these, not stock, certainly not cheap, but nice looking. https://www.ghezzi-brian.com/en/tuning-moto/tuning-moto-guzzi/v11-1100-sport-daytona-centauro/belly-pan/

20mm. My sideplates including footpegs and pivot pins are scheduled for delivery tomorrow, I guess I'll delay leaving town for another day to keep curiosity from eating me while away.

Has anyone got a V11 Le Mans belly pan for sale? preferably UK? many thanks. D.

NOPE . I am wrong . there is a fitting and hose at the top of the frame (visible) at the front of the fuel tank and goes back to the air cleaner housing that vents to the inside of the housing. This keeps crankcase pressure from building up and ruining things . My apologies for the heresy.

Mate, down here Rough as guts is being polite.... Shiraz time by the way ... Cheers
