    Exposing Oil Picc-up On Steep Grades

    in Technical Topics

    Posted

    Yup, it's possible and in many cases quite easy. The oil pick up is in the front right hand (? this is from memory at 4.30AM.) corner of the sump. Uphill and banking to the left is the most risky. It's a problem that Guzzi finally, obliquely, acknowledged with the launch of the Breva/Griso/Norge motors which have a far better sump design.

     

    Yes, there is a cure, but since I'm the one that designed it I always get accused of venal motives and charlatanry when I mention it.

    Hi Pete, I've send you a pm, about your crappy design rofl.gif . Could you answer me back.

     

    Thx

    I had my wheels powder coated "Red Baron" red. Dont know the paint code, but I can find out Monday if anyone is interested. It was a very good match.

    Dabore, IMHO you could benefit hugely from a re-spring at the rear and at least more preload on the fork. After considering the principles offered here:

    and for final set-up, here:

    . . . wot do YOU think?? :huh2:

     

    If you're interested, I'm pleased to help. But no one here can carry the whole load for you and tune your chassis over the Web. Always pleased to help if you're sincere about wanting it.

    All help is welcome I am still a young driver (23) and in the learning phase. Yeah, I know, you learn whole your life.

     

    For the improvements I'll need to wait for payday 23 may, so I wont be doing anything on the bike until then.

     

    Now I am just :nerd: , soon :luigi: and then :race: . ( ;) ) I am not fat (ofcourse little bit, more big boned ), but I weight with clothes and all other stuff on me, about 260 lbs. So new (stiffer) springs should be a tremendous improvement. But what about that click in the front forks, what could that be?

    I didn't figure out yet if it is in the left or right shim, or both.

     

    No I am off to a BBQ. :grin:

    Well, I just took measurements on my bike, here are the results:

     

    Back

    unladen 20 mm

    laden 50 mm

     

     

    Front

    unladen 30 mm

    laden 40 mm

     

    I also think there could be something wrong with the front fork. When I am on the bike, I push the fork down and release it, I hear a click.

    What do you think? :huh2:

    Every (functioning) carb I've ever seen has a "reference" line at the edge of the carb bellmouth that feeds into the float bowl; this normalizes the pressure in the float bowl against ambient to enable utilization of the relative vacuum created by the constriction in the throat of the carb created by the slide/butterfly (1) ["Welcome to fundamentals of carbeurator theory 101"... :thumbsup:]

     

    Now, as to needing to balance the "ram air" pressure in the fuel tank so that gas can get the float bowl, that's a different matter irrelevant to your statement above. ;)

     

    Anyway, the ram air theory behind reversing the heads has some merit, tho' not due to "ram effect;" it's more a matter of getting cooler, denser air from the front of the bike before it has a chance to heat up in its trip around the hot engine. Unfortunately, as someone else already pointed out, the ex. pipes kinda need to be in front on an air-cooled engine, at least 4 strokes, to keep the ex. valve from burning up.

     

    On a water-pumper, putting the header exiting the rear has some interesting advantages, so much so that when noted bicycle maker Cannondale was looking at branching out into dirtbikes, their prototype had the "reversed but really forward" engine config...

     

    Ride on!

    :bike:

     

    (1) -yes Virgina, there are butterfly carbs out there w/o any kind of slide at all; I think Revco builds one...

     

     

    For an air-cooled motor, having the exhaust side of the heads tucked away out of the wind altogether, instead of as directly as possible facing into the blast at speed, is more than a theoretical problem. It presents a prohibitive practical problem. But as we're so often reminded, people will do almost anything to their motorcycles to attract attention for posing purposes -- even to the extent of rendering them practically unusable for riding. <_>

     

    Air cooled heads on backwards = Rider's head on backwards. :whistle:

     

    "Ram air effects" for a road bike = loopier than a bag o' squirrels. <_>

     

    Yes, I know they've been selling "ram air" f'er half a century. PT Barnum was a terrific salesman, too -- ya gotta give 'em wot they're buying. . . . :lol:

     

     

    My guess is they will find out pretty quickly why people stopped doing this experiment in the 1970's.

     

    By reversing the heads you get inadequate air flow to cool the exhaust sides properly and the heads fall off the exhaust valves. Also any sort of 'Ram Air' system requires a large air box to act as a plennum chamber and doesn't start to deliver any real, tangible, benefits until you're going at 130MPH plus. It's a gimmic. An interesting and stylish gimmic but it won't deliver any performance increase.

     

    As mentioned above you can't simply whack the heads on left for right, you need to grind up a different camshaft. Terrific waste of effort. It's a nice looking machine but....

    Me too!!! After June, I will remembering when the V11 forum was all fields, wetting myself with regularity and spending my life puzzling why those pesky youngsters don't sort out their suspension before throwing useless money at their engines! :huh2::oldgit:

     

     

    Lool :lol: I am one of the youngsters here (23) and I know that you are reffering to ratchethack.

    Hello people,

     

    Surfing on the net I found this two pictures. They show a race custom guzzi. The most shocking mod is, that the air intake and the injectors are on the oil cooler spot and the exhaust tubes are now behind the cylinders. :huh:

     

    Never seen something like that before and is very cool, specially with those termi exhaust pipes B)

    What do you think? :D

     

    The pictures came from tlm.nl site

    I love this site

    Which v11 owner doesnt like this site?

     

    I am also a member on two other cycle forums. On one I get very stupid answers. On the other I really dont feel like I belong there, becasue they are little v11 owners and a lot post 1980 guzzi owners.

     

    And not to forget, the endless discussions of dlaing :thumbsup: and rachethack :thumbsup: . You could write a novel about them :nerd: , mybe 3 novels :lol: .

     

    Final shout-out to admin king_smiley.GIF Jaap doing a great job with the site and all other moderators helping him.

    No choke !?

    in 24/7 V11

    Posted

    recently I've imported my v11 sport from germany. It's from june 2003. Going trough the manual and workshop manual. They have pictures of the choke and all. Now I am confused, because I've always thought that choke go with carbs and I have electrical injection. :huh:

     

    I've no problems starting the bike, just turn the throttle a little bit and away it goes.

     

    This is my first bike, so dont kill me :P

    More pony's please

    I think you cant compare a hayabusa with a guzzi. First the 4 vs 2 cylinders. Then 4 vs 2 valves per cylinder. Japan vs Italy. :nerd:

     

    Second, I want to ride my v11 on a daily basis, home-work. I want it to have good fuel economy and all weather reliability. So I put my money on those things. :D

     

    When I bought my bike, it came with bos slip-on exhausts. What are your opinions on that?
