A picture puzzle riddle: What is missing from the below photo?
right: there is no speedometer. At least large parts of it. The speedometer of my Japanese Präzisionskrades adopted on Saturday morning at half past ten, when I was with a speed of 120 dead straight on the A92 road towards Landshut was. I have not noticed at first because I was too busy trying not to freeze at temperatures from 1 to 2 degrees Celsius, while I tried to keep in contact through mist of drizzle around the airport Erding least rudimentary view of the road. Why in the world is a train that still has all his senses together, with the cold pig on a motorcycle to Landshut, where he could still take the car - or just stay home in bed?
Well, we - my Japanese Präzisionskrad and I - had a date with Eric, the screwdriver God. Erich screwed for years to Yamaha TDM, he knows every part of his first name, and after the service for which I have my workshop the other day over 200 € paid thrown into the maw, I'm inclined to say: Erich , the better.
My Japanese is Präzisisonskrad Yamaha TDM 850, TDM friends they can just call. The old lady is in February 19, since one has ever one or the other aches and pains. In October TÜV was due, no big deal, I thought and wanted to bring the machine to the workshop for motorcycle mechanics eV. The care is usually quite selflessly with the TDM, and it is also a good thing it works: on the SRC socially disadvantaged young people get an apprenticeship and learn something clever. At the moment they learn nothing, because the SRC makes winter break until January. So THIS MACHINE contacted one in the west of Munich and it is a TÜV-date calls. Appointment made, machine made, "If all are well?" "I think so?" "Okay, said Thursday it is ready."
On Friday I got my from TDM, the garage man told me that new brake pads forward received; and that the front brake piston "somewhat sluggish" were that we could but just take it. A TÜV report is explicitly stated that the brakes are roadworthy and that on the test drive, the road was wet (did you ever see once in a TÜV-read report) on the Nachhausweg I noticed three things:. First, the front brake had no reasonable pressure point more Second, the safe travel of the lever was at least twice as much wiedrei days ago when I had taken to the MOT and the third, after repeated brake pump was harder - a sure sign of air in the brake system.
bring you back again, that would naturally have been a method. Unfortunately, a lifetime of always has the possibility to build in new parts for an infinite amount of money if they do not come with the 19-year-old originals clear. So, once home, after all, she has now made a fresh TÜV seal and perhaps this is the air in the brake a little bit, too.
There was not. It was also not worse, but it did not make fun. So I made an appointment with Eric, waved me on Saturday on the TDM and rushed off to Landshut, about 100 kilometers of track one. I was cold, missing the rubber wiper on left index finger of my motorcycle summer glove, with which I can in the rain the visor kept free of my helmet (which is missing, strangely enough, the winter gloves from the same manufacturer) - and my TDM threw off her speedometer, God knows why.
When Eric arrived, we went straight to work. The bleeding the front brake a Yamaha TDM 850 is a task for one who has killed his father and mother, that's for sure. The entire brake line system from the Brake handle (TDM has two of them on the front wheel) to the two brake calipers must be completely evacuated, have an air bubble the size of a pinhead is enough to make the pressure point as soft as rubber. Unfortunately, the screws are to bleed down to the brake calipers. Air but has the unpleasant characteristic upward rise. What's more, the brake lines run from both brake calipers on a so-called connector, which is a compound that makes one of two lines. So, therefore, air bubbles from a wonderful hike to the other brake caliper, brake fluid fills in while up and down on it waiting to come out that at the bleeding nipple air bubbles. On that occasion, Eric noticed the way a difficult continuous bleed screw - so hard as to doubt that this screw dürfenob be allowed at the last shop visit was ever used.
There's quite a clever way to bleed brakes: You press the brake fluid from the bottom up through the lines. Any trapped air is pushed upward and appears on the reservoir from the handlebars again. You would need a large syringe and a flexible silicone tube. To the syringe but it gebrach us, and now was also difficult on Saturday after lunch. So we fiddled around until the afternoon by two and the ugly smell of complete failure was in the air - the DM at that time had no front brake pressure even more, the lever could pull up to stop resisting. Finally, Eric still operating on a syringe, spilling the oil for a chain oiler. After half a bottle of brake cleaner and a lot of attention was the manual syringe free of oil and almost virginal. So we managed the feat. Eventually, an air bubble bubbled big as a veritable Pfurz from the reservoir, followed by a controlled fountain pure brake fluid. And the pressure point was there: Clear, transparent, exemplary.
What has this got to do with the speedometer needle?
The Erich would have preferred to be repaired immediately, but we had no more time. He still said "Can you stick with super glue," he dismissed me on the cold way back to Munich - with a good draft front brake.
Today I have accepted me the speedo problem. The tachometer sits in an instrument cluster, and this is actually expanded quite fast: speed shaft, four special plug pulled, two # 10 nuts away, already holds one piece of the good in the hand. Okay, before you have to unscrew the three-part course, machine guards, that makes all the more fun, the colder it is. But today I was in good shape: After half an hour I held the instrument cluster in the hand, five minutes later it was unscrewed to our table and I trudged through the drizzle to the drugstore to buy glue. 
The 2.85 euros, which I have spent on a bottle of UHU glue a flash ", proved to be unfortunately out a little later as a waste of money, because even though acted strictly according to regulations, the stuff stuck about as well as spit. The picture here is deceptive: Not ten seconds after receiving the pointer fell back on the dial. So everything is cleaned and a little epoxy glue found. The mixture is ready, so that everything stuck, of course not quite as smooth and seamless as with glue, fixed, waited half an hour set. then bolted together the whole circus again, instrument cluster to the motorcycle fairing to the frame, while the other way threw the large ratchet box, 50 pieces of sidewalk geklaubt and re-sorted, shamefully cursed, while the stupid neighbor deliberately not greeted. Finally, once pulled on the brake handle. Somehow feels soft. Obviously we have
but does not catch any air. Update: now seems to have dissipated the air. The pressure point is okay.
