    Are you trying to say that BMW and Moto Guzzi have succeeded in
    directing cooling air to the clutch, or that both marques use a larger
    diameter single disk clutch?

    I threw away my R-69 manual, feeling that I was unlikely to ever
    acquire an old airhead...

    BMW's and Guzzis have granny gears in their transmissions, and the
    riders probably spend all their riding lives on nicely paved roads, so
    there is little need to ever slip the clutch like the designer of the
    multi-plate clutch intended.

    Clutch slipping makes up for a taller first gear which is more useful
    on the race course.

    The highest performance literbikes can now reach 100 mph in first gear,
    while my low-geared water buffalo would barely reach 35 mph.

    I was a "committed rider" for years.

    "Committed" in the sense that my income and job prospects had committed
    me to riding to work on a motorcycle, riding for recreation on a
    motorcycle, and using a motorcycle as a pickup truck any time I wanted
    to move, say, a 50 gallon aquarium across town.

    Yes, you could call me "independant", too. I never asked anybody what
    *their* plans for the day were, I just went ahead and did whatever I
    wanted to do, whenever I wanted to do it, and, if that meant I was
    doing it alone, that was just fine with me, I was comfortable
    with my solitary self.

    The average citizen would say that I should be *committed* to a mental
    institution for riding in weather where the rainwater flowing off
    freeway overpasses loked like waterfalls.

    The average cop looked at the way I was dressed and figured that he
    might be able to talk a judge into committing me to a correctional
    institution for *some* offense against the social order, all he had to
    do was check my papers and he would surely find *something"...

    I was more committed to riding than the other committed riders that I
    knew. I was manically putting 2000 miles a month on my water buffalo,
    and trying to tell them that they were missing out on some of the
    grandest experiences possible by sleeping past the crack of dawn, or
    going to bed just before dawn and sleeping all day to live like a
    vampire and come out after dark...

    Other riders have boasted that they have been licensed for 20 years and
    have never owned a four-wheeler. I can understand where they are coming
    from, having been there, done that, and left it all behind for a
    multi-vehicle lifestyle better than the average.

    I recently sold off all the souvenirs of my world travels, acquired
    whilst jetting around the world on package tours. One guy who purchased
    some of the junk marvelled, saying,
    "You've really been blessed".

    Yeah, well all of that materialistic stuff tends to adhere to a person
    over time, and I once again eschewed it in favor of monistic
    simplicity. Who *needs* five color TV's, three computers, four
    motorcycles, three cars and a hundred porn videos anyway?

    I'm getting off the track of what the "committed rider" is like.

    They are often the lone inhabitant of a single room in some apartment
    building and are rarely seen in the company of a female of the species.
    One old bachelor that I know rode from Conecticutt to San Francisco on
    the back of a Triumph during the Viet Nam war.

    His draft card burning brother continued to Vancouver where he lives
    today. The old guy
    only recently sold his final Honda, which he only rarely rode across
    town.

    Another rider proudly declared that he was a committed motorcycle rider
    and that he'd never owned a car and never would. He shared a two
    bedroom apartment with another
    similar social retard who'd also never married and also blamed his
    mother for his clinical desperation.

    Both of those guys are dead, and maybe their alcoholic friend is still
    riding to Alcholics Anonymous meetings every night and trying to seduce
    other recovering alcoholics into the joys of single room occupancy and
    committed motorcycling.

    Their other buddy has become a drug rehab counsellor, figuring that his
    extensive experience with certain substances was imminently qualifying
    for the career.

    I occasionally see one of the "old gang" from the motorcycle hangout.
    He had to sell his
    motorcycle and all of his possessions before going to prison for some
    kind of marketing scam.

    I remember how he criticized my "committed biker" lifestyle back in the
    "good old days".

    He told me that my motorcycle was all that I owned and that he
    "couldn't live like that".

    Now he talks about how he misses the "camaraderie" and he wants to get
    another motorcycle and try to recreate those days.

    Yeah. Right.

  3. No, I'm merely saying that your original assertion that you can't cool a
    car-type clutch on a bike was, and is, bollocks. And nobody mentioned
    size.
    Both BMW airhead boxers, and Guzzi vees, were (and still are) raced,
    using their original clutches, with great success. Classic races
    nowadays, of course.

    A friend bought an early R65, and took it for a holiday to the south of
    France - about a 2000 mile round trip from where he lives. The gear
    return spring broke (not unknown on the early R65 until they modded it)
    in France, leaving him permanenetly stuck in fourth gear. And he was
    two-up. He made it all the weay back in the one gear, sliping the clutch
    all the way to about 30mph. Made it. The clutch was toasted, of course,
    but I'm afraid it illustrates that you're talking crap.
    See above.

    It *might* help your cause if, occasionally, you admit you're wrong.

    Depends on what you're trying to do when you park the motorcycle. Maybe
    he doesn't want somebody to scratch his perfect machine or knock it
    over by parking to close.

    I pulled in to park one day, and was sharing the stall with a Harley
    rider, and he yells at me, "Do you have enough room there?"

    So every time I see the guy pull up to park, I yell at him, "You got
    enough room there, old man?"

    Another guy I know will yell at pedestrians if they cut through the
    space he's parked in, on their way across the street. When they yell
    back, he says, "What don't you use the gawddamned crosswalk, like
    you're supposed to?"

    Our group of regulars at the hangout on top of the hill saw that we
    were in competition with cars for our preferred parking spaces. We
    would park two to a diagonal stall, and sometimes two riders would
    depart from two different stalls, leaving enough room for a car to
    slide in between, straddling the dividing line.

    So we tried parking diagonally in the diagonal stalls, but that upset
    riders who didn't know us, they couldn't figure out what we were up to.

    Besides, Harley riders just have to park backwards, facing out so they
    can make a dramatic exit.

    Finally, we decided to divide four diagonal stalls with extra center
    lines, and we came out with eight stalls, which was just fine for our
    tight knit group. We brought the paint out and laid down some masking
    tape, and "voila!* (1) we had motorcycle parking stalls, and we got the
    maintenance supervisor (this was on city property, mind you) to cut a
    stencil forbidding violation of a municipal code that he made up on the
    spot.

    So there we are, sitting fat dumb and happy, and along comes a fat guy
    on a Suzuki Intruder. He begins telling us that the motorcycle parking
    spaces existed because some semi-hemi-demi-quasi wannabe outlaw biker
    went to the city and demanded motorcycle parking spaces in all the city
    parking lots.

    "Bullshit!" sez I. "We painted these friggin' spaces ourselves, and we
    didn't ask G*d or the Superintendant of Parks and Recreation, we just
    did it."

    Fat Boy gave up after the second time I called "Bullshit!" on him.

    Then, as the number of committed motorcyclists began to dwindle, cagers
    started parking in our motorcycle spots, taking up two spaces. Once one
    cager was in, the other cagers thought it was open season on motorcycle
    parking spaces, so we started parking across the motorcycle stalls so
    we would have space to park and mill around.

    Naturally, along comes a Harley rider who has to park backwards, and he
    wants to know
    why the heck I'm taking up two motorcycle stalls, and I have to tell
    him that the motorcycle stalls are OUR stalls, that we painted the
    lines.

    And he proceeds to tell me that he's been coming to that hangout for 20
    years and he has as much right as anybody to park backwards. I tell him
    that I've been parking there for *thirty* years and that if he'd ever
    been there before, I would *know* him.

    (1) Notice that I spelled "voila!" correctly.

    The worst thing I ever carried home on the bike was a ladder. I had
    to sit on it. That was a real pain in the ass.
    I'm blessed with a wife who loves to sit for hours on the pillion seat,
    with a backpack. She falls asleep on long trips. I can tell, because
    her helmet then touches my back. But she doesn' fall off.
    Exactly what I sometimes wonder about. I must be nuts. My favorite
    weather is snow. Everybody takes a car to work, I do not even have
    a car license.
    I must be nuts, which is what many people think of me.
    Not to brag: Daily to work and back + bringing my wife to her work
    and late at night pick her up again, made me do 40.000 km per
    year. All those years, I missed one day. Icy road (people went skating
    and some went skiing to work). I picked my beamer boxer, stood
    beside it and kicked the starter. The bike slid away sideways, and it
    was so slippery that I could not pick it up. So I decided let it lay
    there on it's side and to stay home.
    My wife bought a car when her working hours shifted and I could no
    longer bring her to work. I must admit, a car sometimes is a handy
    tool.
    I've visited the birthplace of my wife in Indonesia. In the middle
    of nowhere. They have no roads, no electricity, no running water.
    We'd think of them as being poor. But over there, nobody has a TV,
    or freezer, or any other goodie. And because nobady owns something,
    they are not really poor. Drawback is that when you break a leg,
    you are doomed. No hospital around. And if they bring you those
    50 miles by perahu to a hospital, you need money, which they do not
    have too (no factory to earn money).
    I there discovered that I was in a rat race at home.

  7. When I started riding in the '50s, my town (Louisville,KY) still had streetcar
    tracks. You haven't lived till you've gotten your tires (or worse, ONE tire)
    stuck in an icy streetcar track :).

    How about one of those potholes next to the track that's about 2 ft long
    and seems to go to the core of the earth, while the rear wheel is
    skidding across the track trying to spin you like a ballet dancer?

    No, hasn't happened to me, just fantasizing

    How do you say, "I went native," in Dutch?

    There used to be a comic strip in the Sunday newspaper, called "The
    Katzenjammer Kids". It was about the Dutch planters in Java. But most
    Americans didn't understand the milieu and the humor of colonial
    imperialism during the Indonesian struggle for independence...
    A friend of mine had a mild stroke when he was about 53. The doctor
    asked him what kind of work he did and he told him about his low stress
    job working in the same place for 27 years. The doctor then asked him
    how long he'd lived at the same address and he also answered that he'd
    lived there for 27 years.

    The doctor said, "My God, man. You're in the deepest rut I've ever
    heard of."

    My friend retired to a life of travel and leisure and lasted another 27
    years. He had his final heart attack in the mountains of Mexico where
    there was no hospital or emergency services for 100 miles. But his
    friends said he died with a smile on his face...

    Most Americans wouldn't know when it was time to quit working and
    relax. They move from house to house (or apartment to apartment) about
    every three years and change jobs as often.

    They stress out and have a massive heart attack by age 65, and never
    get to enjoy retirement.

  11. I think he's trying to tell you that they both use single disk
    dry clutches without overheating problems.

    The diameter of the single disk is a little larger than some
    multi-plate clutches. The total surface area is likely somewhat
    less.
    My BMW GS goes offroad pretty regularly with no clutch problems.
    Less dirt capable than a KTM perhaps but way better than any other
    liter bike I can think of. Very occasionally, I've produced clutch
    smoke trying to get it up a hill full of big rocks. Still get plenty of
    life out of the clutch. I'm on my 3rd disk at 135,000 miles and
    could have probably stretched it further.

    I had to look this up in my dictionary, because I did
    not know the meaning. Translated: "Ik ging inburgeren".
    A 'burger' is a citizen. "inburgeren' is a noun. It is
    a brand new word, and currently *the* topic of
    political parties, that shout that Turkish and
    Moroccan people living here must 'inburgeren',
    meaning they should become like us.
    Will the time ever come that I see a woman
    on the beach taking off her burqua and lay
    down topless?
    And do I *really* want that to happen?
    I would not call that period *humor*. It was pure colonialism
    exploiting the Indonesians. The awkward thing was that
    we (me too) did not realize that.
    For work I've been in the US a couple of times, and usually stayed
    with a good friend I have in Ohio. I was totally flubbergasted
    when -on a saturday- he phoned the company to see
    how another colleague was dealing with some problem.
    The sheer fact that he thought of the company on a weekend day,
    plus the fact that some 'idiot' was working in his free time (unpaid)
    left me stunned.

    The company was Lucent. They sacked almost everybody
    when times got worse (including me) an gave the CEO
    (Rich McGinn) a load of money when they laid him off.
    Lucent did not even say 'thank you' when they sacked me.


    Hey, we are way off the cluch question.

  13. My feeble recollection of the strip says it looked way more
    like Africa than it did Indonesia. Agreed completely that
    it was insulting. I sort of remembered a native king and a
    search seems to confirm this.
