  1. My experience with the CBX 1000: a bloke I shared a house with in the early nineties had one. It was in pretty good nick, and I was able to ride it a number of times. My bike at the time was a 1976 Kawasaki Z900, so as you know what I was comparing to, but I rode a lot of different bikes belonging to various friends at the time, so I wasn't "one-eyed". Incidently, the bloke with the CBX also had a Le Mans 850 III, and it is predominantly his fault (for letting me ride that as well) that I now own Guzzis. B)

     

    Anyway, the CBX is big and heavy, and has a late 70's japanese frame. 'nuff said.

    And it is an enormous amount of fun. That motor is absolutely fantastic.

    Although the motor looks enormous, it actually isn't any wider than the Z900 motor. I know this for certain. I measured them.

    The one in the photos: I reckon you're right about the "buying it as a project". Either he's done a "pimp my ride" on it to turn it over, or he started in on renovating, and has given up for some reason. The photos indicate that he got into the carbs and brakes, not purely cosmetic things, so maybe he really intended to finish it off.

    If I had the readies to get it finished, I would buy it. I reckon a CBX in good nick must be like hen's teeth, and if you do find one, it is likely to be astronomically priced. I'd be inclined to take the risk. When it is finished, you know what you've got. The risk is that there is something in there that needs doing and might break the bank. But then you might not, and at the end of the day you would have a brilliant bike. :huh2:

     

    EDIT: if you buy it, throw away those stupid handlebars immediately, and put something useful on there. The ones in the photo would undoubtably turn a reasonably sporty bike, according to the standards of the time, into a heavy pig.

    Es sieht auf jedem Fall stark danach aus. :grin:

    Willkommen zurück hier. Ich habe mich hier mittlerweile ziemlich eingenistet. B)

    About wind noise, the only way to not have any, is to have a separate recorder.

    No, not quite. The only way to not have wind noise is to effectively protect the microphone from the wind. It doesn't matter if the mic is built in to the camera, a seperate mic connected to the camera with a cable, or a mic connected to a seperate recorder. You have to isolate it from the wind.

    That isn't even all that hard. A couple of layers of rubber foam taped over the built-in mic on a camera should do it. If you want to really pay attention to sound quality, the foam or whatever can get expensive, but if you are using something with a built-in mic, don't worry about it.

    As I said, it isn't all that difficult, actually. All it takes is a bit of common sense, a few minutes of thinking sensibly about the problem, and the awareness that one has to stop wind getting in without damping the pressure waves (sound waves) too much in the process.

    The wind protectors that look like a fluffy gerbil work quite well, incidently. B)

     

    As far as the camera person goes, towards the end where the bloke is talking after his ride: 1) the camera follows him to the bike where he talks for a minute or two, and the bike's mirror is in front of his face most of the time. 2) he sits at the table and talks for several minutes. During that time the bike in the background is in focus. Ok. But he is not. Not OK. Just to mention a couple of points.... :whistle:

     

    Yes, I'm picky, and nit-picking is easy. But getting it right isn't that difficult either. :huh2:

  4. Well, the bike is pretty.

    The film is mediocre. The camera person is an amateur, and they don't really have the audio sorted. Wind noise should not ever happen.

    And the bloke corresponds almost perfectly to the classic stereotype of a public school twat. Ok, that is not really fair, and perhaps says something about my personal predjudices, but still... :whistle:

     

    But the bike really is pretty. Pity I don't like parallel twins. B)

    I don't know what the GPS data entails.

    The first thing that occurs to me is that all the teams will be able to see at all times where all of the bikes are on the track. And be able to calculate speed information out of that.

    Not entirely useless information, I would say. :huh2:

    ...The rear tyres on both trips easily lasted...

    Yeah, that's not so much the problem, although they do get a bit flat in the middle. It's more the front tyres. Not so much that the profile dissapears, but that you (can) get very uneven wear happening. In particular, what is known as "Sägezahnbildung" in German, i.e. "saw-tooth developement" more or less. That thing where the tread blocks wear more on the leading edges, and you get steps developing from one to the next.

    I've had front tyres that still had enough profile to be legal, but were really not good for the handling on the bike. :huh2:

    Tyre pressure is critical. Too little pressure accelerates the process dramatically.

    Autobahn cruising makes for decent tyre life.

    I beg to differ.

    If you are constrained to the consevative 110 km/h that is allowed in Australia, yes. If you are really on an Autobahn, it depends entirely on how fast you are prepared to ride.

    My normal cruising speed on the GTR 1000 was about 150 - 160 km/h (average, mind you. Peak around 180 km/h. More than that, and I start getting nervous on public roads...). That, particularly on that heavy bike, is not exactly conducive to long tyre life, front or rear. B)

     

    And smooth B roads are only the norm in southern / western Germany. Here in the region around Leipzig, and in fact all of what was the DDR prior to 1989, you get everything from freshly made roads through "patches on the patches" to cobblestones. Makes a trip across country through unknown territory quite interesting. :whistle:

    EDIT: having said that, even around Heilbronn, where I lived previous to Leipzig, there were some pretty shitful roads. That is in Baden-Württemberg, which is a pretty well-off state, but some of the back roads are still pretty ordinary. :huh2:

    ... I get the feeling this bike may have spent time under the weather....

    That might explain the black seat. Look at the photos here. The site is not 100% reliable, but when the included photos are of the right bike, they are apparently mostly catalogue photos. The ones in this article confirm what I thought, i.e. that the Tenni should have a brown seat.

    EDIT: I see in the ad that the original brown seat is included. I wonder what condition it is in... :huh2:

     I'm really not convinced a bigger tire will automatically provide more longevity. :huh2:

    Neither am I. As far as I know, the longevity is in a direct relationship to the compound, not the tyre size. :huh2:

    ....leaking fuel injectors.

    You could check them on the bike I guess as a back yard method

    If I were to do that, I would use Guzzidiag. It has a function to activate the injectors manually. This allows one to see if they are working, how much they are injecting (catch it in a glass and measure the volume), and what the spray pattern looks like (put a piece of paper in front of the injector whilst it is being activated). During the process, as the ignition is on all the while, it should also be possible to see if they are leaking, I reckon.

  11. Tom is on the right track with his questions, I think.

    The output shaft of the gearbox will have a bit of play relative to the input shaft of the gearbox, as will the final drive from the input shaft to the wheel drive. That is normal.

    The drive shaft should sit tight on the bolted up splines, both the one out of the gearbox and the one into the final drive. The uni-joints have no play at all in them when they are good.

    You need to have a specific look at all the steps along the way.

    PS: at 6,000 miles I would be checking if it is all apart anyway, but not expecting any trouble. Assuming the bike hasn't been mistreated.

    Anuvverps: there is also the sliding spline in the middle of the shaft that compensates for the difference in length as the suspension goes up and down. That will have a very small amount of play. If it didn't, it wouldn't slide. :huh2:

    the high idle cable always goes to the right TB as far as I know 

    That's how it is on mine, as far as I remember. Throttle cable to the left throttle body, and high idle on the right. On the Breva 750 i.e. too. :)

    As far injector issues, is there a basic, quick check?

    I have only read about this, but it sounds easy. B)

    Guzzidiag has a function to activate various things to see if they work. One of them, as far as I understand it, is the injectors. The function is on the page accessible from this menu next to the green mark I made on the screenshot. I can't get further than that without it being connected to a bike, but I think that should show where to find it.

    EDIT: "Ansicht" is likely to be "view" in the english version, and "Aktoren" may be "actors" or something similar to that. The positon in the menu is almost certainly the same.

    As far as I have read, it is as easy as screwing out the injector, connecting Guzzidiag, and activating the function. It shows you if the injectors work at all, and, assuming they do, allows you to see what the spray pattern looks like and/or see how much fuel they are letting through.

    I wonder why the shock is upside down.

    I made that mistake myself, but was uncertain enough to ask about it here

    Looking at the photos of that bike, and being polite enough to assume the bloke is not hopelessy stupid, I reckon his custom seat frame might have left him no other choice.
