My Date with the History of Motorcycles

Milwaukee is famous for two things, first its home of Harley Davidson and then its also home of one of the finest breweries of America. So during my stay in Milwaukee i decided to take the opportunity to visit the base of Harley Davidson. First of all it was amazing to see their power train operations but the real glamor of the trip was the visit to Harley Davidson Museum.


It was great to see the history of motorcycles along with illustrative models to describe the working of engines, interactive system to tell about the complete product life cycle right from the concept stage, all the engines of Harleys in working condition and an interactive system, with which you can listen to the patented sound of various engines. It was not my first trip to a motorcycle factory, but still the experiences could not be compared with any other thing. And at the end of it all, I was allowed to configure my own Harley, and then it was sent to me by e-mail (unfortunately only the photograph).


It was nice to see the bikes built through the past 105 years, with the oldest ones resembling closely with Hero Jet kind of bicycles. with just an engine on the frame and guess what all the controls were on the top of fuel tank. You look at the photograph and you will end up saying.. oops that's an Harley, but once one goes through the whole range, s/he will realise that its not just the living creatures that followed Darwin's theory of evolution.



Just look at the stand of the bike, It would have been difficult for sure to the bike on stand.



And guess what a bit modern bikes in 1910s were even used for motor sports including Motor Cycle Polo (well you replace horses with Bikes) and racing.





It was amazing to see the way American Industry responded (might be it was an obligation) to the requirement by the nation at the time of war. During both the world wars Harleys played significant role and for some years even civilian models were completely blocked to dedicate all the capacity for defence production, and if some capacity still remained that was utilized to produce bombs. Even at Kohler, the scene was same, I wonder how a ceramic products factory can produce bomb shells but it has happened.



After the end of World war II, Harleys were back in action amongst the common people. and then started the era of experimentation with the bikes, and I tried capture a few of them I found most amazing. I have seen such bicycle with a couple (or more ) paddles but a motor bike with two engines and even two fuel tanks is a bit too much.


And then a tiny Harley, I still remember the tiny Rajdoot, but the size of this Harley was good enough to qualify it for children, which can fit in the back of a station wagon, but it was made of fully grown people.



Following I am not sure from which angle gets the qualification to be called as bike, with an engine as big as Tata Mini truck.



Then is the one which is a tribute to the long standing relations between Pakistan and America. You can compare it with pakistani trucks, looks like the designer was deeply impressed with the visual appeal of those trucks but I have enough reasons to believe that the experiment was not successful. (Actually this was done by some one who was supposed to stay home as he was ill)


Finally the engine room, which had all the Harley engines till date. I will post the videos later, which contain sound of Harley engines. The section also had very good illustrative models to explain the working of a four cylinder engine, gear box, fly wheel (and its gyroscopic action, which contributes to stability of bike). I think this would have made the Internal Combustion engines subject easy for us way back in 2002.



After all that gyan, I finally get a chance to sit on a modern looking bike made by the same company with Buell Brand.

I am visiting Miller Brewers this Saturday and will update you all about the beer making.

My first experiment with electro Magnetic waves...

I remember little about the time we had a black & white television. That was in 1994. Cable must have just about. Maybe at the time I didn't even have enough sense to think about getting a cable connection. The television used to be kept in a room on the first floor of the house. I was sitting alone watching it. At the time b&w televisions didn't have remote controls, but perhaps now they do. Sitting all by myself, I thought why not twist the television's ears and change channels. Thought to myself that just like the transistor catches radio and FM waves, maybe television will catch some of the cable channels. Twist by twist, I reached one such channel which was showing a film. I thought why not try and move the wire around a little to see if the image clears a little more. But the image didn't change. I thought something must be done so I can watch cable. The cable-guy's satellite was just five steps away. The wires were tied to an electricity pole in front of the house. All that separated me from them were the electricity wires to the pole, and the breadth of the lane. I cast a glance at the rooftops in the market. They had tied a speaker, the rim of a cycle and a magnet to the antenna on their roofs.

I thought, something has to be done. I went to the kabari (scrap dealer) shop in my lane and bought a cycle rim. Then, went up to my roof, removed the wire from the antenna and tied it to the cycle rim. Back downstairs to the TV, I saw cable (transmission) was clear. When mummy came back from her vegetable shopping, she was surprised to see a new movie on television. She asked me, "There is a new film on the television?" I said I made it happen with my brain. Mummy said, "What did you do?" I told her to go up and see for herself. I was sitting downstairs, watching the film. Mummy quietly went up and removed the rim from the antenna. I thought maybe there is some problem from the main transmission. Mummy came back down and said, "Go return this rim to wherever you got it from." I asked her why she had removed it. Mummy said, "When your father returns from duty today, we'll get a cable connection." I replied with an 'okay'.

Papa came back in the evening. I asked him to get a cable connection. He said we'd get it done the next day. But I was restless for cable. I sneaked Raju into the house and started to think about a new plan.

And this is what I did - I took the TV antenna wire, removed the insulation, and pulled out the strands of wire one by one. I told Raju, "I'll keep peeling off the insulation, you keep winding it up." Two hours passed. We estimated the length of the wire would be enough to reach across now. I said to Raju, "You go stand on the roof opposite, and throw two small stones from the window." The window didn't have a grill.

I was on the second floor, and just below me was the electricity wire. Raju threw in the stones. I tied the wires I had peeled, the thickness of which was microscopic, to these stones. Then I threw them across. But they got entangled in my hand and landed straight on the electricity wires. The shock I got then! For a second I thought I was dead and gone to heaven. But I didn't relent, and threw the wire once again. Raju was quick. He caught them and quickly swung up his arms. I ran up to that roof, and simply tied the wires to the joint in the cable. I came back to find the transmission was smooth and clear.

Next day, papa said, "Get a cable connection today." I thought, who wants to give a hundred and fifty rupees every month. I said, "Let it be. What's the need."
