     boxing is a "sport"

    Whilst I understand what you are getting at, and agree, I must say that I don't like boxing as an example. I consider boxing to be an anachronism, an activity that should have died out some time ago. Two blokes getting paid to beat the shit out of each other just doesn't work for me, and several hundred watching and getting excited about it, even less. :huh2:

    I don't ride for "fun."

    I do. Not frivolously, but per defintion:

    You refer to an activity or situation as fun if you think it is pleasant and enjoyable and it causes you to feel happy.

    Riding is dangerous (which sometimes adds to the kick), requires a lot of concentration, and is definitely not to be taken lightly. But I find it pleasant and enjoyable, and it makes me feel happy, particularly when I get it right and everything flows. :race:

    ...8 months from solo to checkflight.

    Do you happen to know how long that takes on average? I have no idea.

    What I saw in the excerpts in that video didn't exactly inspire confidence in her skills.

     

    I'm doing my best to resist writing a sentence with the word "blonde" in it. :(

  4. And another thing. I haven't had the problem yet, but when I bought my Le Mans I was advised by a very, very well informed acquaintance to get in, amongst other things, a spare timing cover gasket. In his opinion, which I trust implicitly, the gasket is prone to developing a leak. I haven't actually seen anything to that effect here, but perhaps other members could comment.

    As far as localising the leak goes, clean everything up impeccably. Go for a bit of a ride, and then dust the suspect areas with talcum powder (scented or not doesn't make a difference...:whistle:). That tends to make a frightful mess, but shows up even very small leaks very well, and helps a lot in seeing where the oil is really coming from.

    ... I reckon it’s from the timing chain gasket...

    Apart from anything else that it might be, be aware of the breather hose that runs from the frame behind the steering head to the top of the motor just in front of the gearbox.

    This is the hose

    part #18 on the parts diagramm

    The hose gets old and hard, and cracks. The cracks seem to generally happen at the first bend away from the ends.

    When the front goes, it can look like a leak from the front of the motor somewhere. When the back goes, it can look like the rear main seal is gone, i.e. the seal around the output shaft to the clutch.

    If you have just bought the bike, it is a good idea to have a look at that hose as part of the "getting to know the bike" ritual, even if it isn't the cause of your current leak. It is a part that has to be replaced periodically.

    The slider to lower the sun visor is on top of the helmet. What happens under a serious rain? does the water filtrates in?

    I expect you'll find out sooner or later. B)

    But I can't imagine a helmet producer not having thought about that. I expect that the mechanism is more or less water tight. :huh2:

     

    If you really want to know, put the helmet on, and go under the shower. :whistle:

    This is why I exclusively use audio navigation.

    Different strokes, and all that. I have the audio on my navigation device switched off all the time, in the car and on the bike. I absorb information much better visually than aurally, and having to try and figure out what the machine is telling me is far more distracting that a quick glance at the screen. :huh2:

     Didn't stop me from getting Tinnitus though :( 

    Unfortunately, tinnitus is not only caused by exposure to loud noise. Mine is most likely to an extent due to noise exposure, but probably not entirely.

    As far as I know, it is not really understood what all the causes could be, but I believe stress could be a factor, as well as who knows what else.

    Fortunately I mostly don't notice mine unless I actively think about it, but when I do, it is really loud. :(

    How is "manifold pressure" different than "intake vacuum?"

    I started writing an answer to that, and then realised that it is probably too late at night for me to formulate my thoughts coherently. Nevertheless, in the course of thinking about it I found this article:

    https://en.wikipedia.org/wiki/Manifold_vacuum

    and realised that I had a "turned around" view of what the throttle does. One tends to think that opening the throttle is "urging on" the motor. As the article points out, in fact opening the throttle is more like "releasing the beast". Closing the throttle is not "turning down the fuel", but rather "cutting off the air supply".

    Without the throttle, the motor (disregarding load) would run at maximun air intake and maxium revs all the time. Introducing the throttle into the equation provides the possibility to choke off the air supply, and keep the motor at idle, or lower than maximum revs.

    So "intake vacuum" is kind of an indication of how much the motor is being held back by the throttle, and "manifold pressure" is the actual air (or gas, or air/fuel mixture) pressure in the manifold at any given state of throttle opening.

     

    I think. :huh2:

    Has anyone asked himself why is manifold pressure quoted as pressure and not depression? since the pistons draw the mixture in the admission phase, the pressure in the intake pipe/manifold should be below atmospheric? Correct? 

    It seems logical to me to state the pressure relative to 0 Bar, as is the norm for pressure measurements generally. You are quite right that the manifold pressure in a normally aspirated engine will be lower than the current ambient atmospheric pressure. However, ambient amtmospheric pressure is far from constant. I am also fairly convinced that the difference in pressure in the manifold compared to ambient atmospheric pressure would vary depending on what the ambient atmospheric pressure currently actually is.

    Therefore, stating the manifold pressure in relation to the ambient atmospheric pressure would be likely to be rather complicated, and require an accompanying statement of the current atmospheric pressure. :huh2:

    Sounded like a Jews Harp in there as well.

    Now that you mention it, indeed there is. Funny, I've been familiar with that song for at least 15 years, maybe 20, and never noticed that.

    I'll put that down to good production: little things that the listener doesn't notice, but put the final touches on the finished product. :)

  11. It is the bit between the final drive box and the rubber dampers in the rear wheel.

    Part no. 18 in this diagram

    Here the picture from Stein-Dinse of the drive side

    and the wheel side

    14335203-z_01_g.jpg

     

    I haven't actually read or heard of one of those "breaking", but the teeth can wear if it is run dry too long. It should have some grease on it on the splines on the drive side.
