IRIDIUM SPARK PLUGS Facts, why is it preferred over normal plugs? Hello, there is no need of Introducing iridium spark plug to you people. It became very popular with the foray of performance bikes into the Indian Market. By the turn of the decade, we are going to witness more and more of these adrenalin injectors. We already saw a quarter litre sports bike in the form of Kawasaki Ninja 250r and also our home grown products like Yamaha R15, Karizma ZMR, Pulsar 220 dtsi, Apache 180 RTR etc. Sadly green baby, Ninja 250R is priced on a premium for most of us bikers in India. But don’t worry, we have our home grown products which are not far behind and also don’t cost us a bomb. So tinkering on the current offerings can yield us better power or at least a responsive feel. TADA….here comes a performance part in the form of spark plug. So what can a spark plug do to improve the performance? I am going to describe the basics of a spark plug and its working so as to clearly understand i...

Hey people, don't rush to your nearest Yamaha showroom.Its only a photoshop work of how the next Fazer 250 should look like.

The current Fz 16 chassis is underexploited to a large extent by putting a puny 150cc engine. It can cope the forces of a single cylinder 250cc engine with ease. With the existing f...

This post is for all my fellow bike riders who wish to extract the last possible juice out of your ride. This post is regarding to the fitting of free flow air filters, its effects and how to rectify it using the method of re-jetting. You need to consider re-jetting your bike whenever there's been a major change to the air intakes (like installing K&N filters which allow more air to pass to the carburetor), or adding drag pipes. Both modifications will lean out the air-fuel mix. The stock jet can only allow a certain amount of fuel to pass through and is designed according to the specification of the vehicle. Installing larger jets increases fuel to the carburetor to restore the 14 parts air to 1 part fuel optimum mix. This mixture is called stoichiometric ratio. Whenever the amount of air intake is increased, the fuel part is also to be increased. In all other cases, the stock jets will take you through 95% of your riding requirements. Since the main jet effects all speed ra...

The crossplane design was first proposed in 1915, and developed by Cadillac and Peerless, both of whom produced flatplane V8s before introducing the crossplane design. Cadillac introduced the first crossplane in 1923, with Peerless following in 1924. In 4 cylinder engines, the technology is developed by YAMAHA Motor Corporation. They introduced this successful design in their MOTO GP bikes and the latest superbike. This technology interprets the positioning of the pistons or arrangement in the crankshaft in an inline engine and also the alteration of the firing order. The rapid torque pulse from the engine is diluted in this way to get more traction from the bike when it is exiting a corner. A crankshaft is a mechanical part in an engine which connects the big end of the connecting rod. Several big ends will be connected to the crank shaft. The crankshaft is also the output part of an engine. Here, in the case of a four cylinder engine, the pistons 2 & 3 are moved opposite by 90 de...

Team-BHP: Harassment for New Joinees! Team-BHP has come up with a new policy that all new registrations will have to be "approved" by them, and only after that will their membership be confirmed. And till then, the new joinees pretty much cannot do anything on the site, be it posting queries or responding to posts. To help Team-BHP in deciding if you are "worthy" of being a member, all new registrants are required to answer a question "Why do you wish to join Team-BHP?" as part of the registration process. You are expected to provide detailed reasoning as to why you wish to join the site, what is your level of interest in automobiles, etc. And there is a warning not take this lightly, since based on the reasons you provide, they will decide whether you are really member material or not! I am actually rejected 3 times. They asked the same question to me 3 times. I answered the same which is genuine. I said, "i learned everything from this prestigious w...

LIVING WITH A SUPERBIKE IN INDIA Riding a bike is more about passion, a cult, and a relaxation for some. But full stop here. It’s not true in the case of our country. While we can buy supercars like Lamborghini Gallardo, Ferrari F430, Porsche 911 Turbo and even a 400 lakh rupee Rolls Royce Phantom from showrooms in India or a BMW, Audi or a Merc in lesser cases. The same simplicity does not apply to a superbike purchase. For some unknown reasons, the bike industry has not kept up with its automotive counterparts and the Yamahas, Suzuki and Hondas of the world seem content with selling 100cc economy motorcycles and now a day with little better 150cc ones. And for showing off, we have 200cc + offerings here from home grown companies like Hero Honda and Bajaj. Kinetic have taken a brave step forward and launched 2 quarter liter bikes with the alliance of Hyosung, Korea. The two offerings from them, a sports bike, the Comet GT 250 and its cruiser counterpart, the Aquila 250. Even though ...
