Motorcycle Tuning Kits

There has always been confusion about the word “tuning” when referring to engines. Personally, I like the dictionary definition: “to bring into harmony.” But with motorcycle engines, there are a number of different applications of the word “tune”:
• Engine tuning
• Tune up
• Race/performance tuning
• Stage tuning
• Fully tuned

For the most part, there are two common, distinct applications of “tune” in motorcycle engine technology. The first is where a stock machine is serviced or tuned up, and the second is where an engine is highly modified or race tuned. Here, we are going to consider the different aspects of tuning an engine for competition, as in race/performance tuning.

It is very beneficial to begin by understanding the way a four stroke engine works. The illustration below covers the four stages of a four stroke engine. This may help you understand just how your performance mods and tunings may affect the engine.

 Why Tune?

The objective of tuning is to improve the volumetric efficiency of the engine. In other words, the engine will, after tuning, produce more power from the same displacement. For example, a 1000-cc engine may produce 125 hp in stock form and 175 hp after race tuning.

It is very important to understand that tuning a single item (fitting bigger carbs, for example) may not in itself improve performance but will, used in harmony with other modifications, produce the required results. Also, fitting aftermarket tuning parts may not result in the hp increase the individual items claim to provide. For example, 10 items each claiming a 10 hp increase may not give a total of 100 extra horse power, as they may not work in harmony (i.e., in tune) with each other.

How Does a Motorcycle Work?

When you get the urge to ride a motorcycle, you start asking lots of questions. Simple things like, "How do I start a bike?" or "How do I shift gears?" Of course, these questions always involve talking about the basic parts of a motorcycle and how they work together. Just to give the steps to start a motorcycle on a hill involves a tremendous number of motorcycle parts. A brand new rider may not even know where to look to find a part. Once the parts are identified by a new rider, they can begin to learn the basic procedures to operate the machine. To get you going, we'll give you pictures of a motorcycle and point out these major motorcycle parts that you need to know. You will then be able to click on the part to gain additional information. I'm using one of my own motorcycles, a 1994 Harley-Davidson Sportster XLH 1200, for the pictures. Now, Harleys can be a bit different from other bikes and I'll try to point out these differences to you. Not all bikes have the same parts in the same places.

Each bike has its own terminology for naming parts and even the way that the parts are interconnected may be different from bike to bike. The following shows four views of my motorcycle. If you click one of the pictures, you will see a larger view. On that view you can move your mouse over the various parts and see names appear. If you click the mouse at that point, you will get more information. If you know what you're looking for, you can just look under the four pictures where there is a list of all the links pertaining to each picture. No attempt has been made to include every part in the various pictures so if you don't see a part described in one view, try another. In particular, the Left Side Detail and Right Side Detail pages may have to be used together to identify the major parts in the area of the motor. Only the basic facts about the parts will be addressed. You can build your knowledge later. Please use the resources provided in the sidebar for further reading about what you need to know concerning the basics of motorcycle riding. This description of a motorcycle will continue to be expanded with new information so you may want to check back often for updates. Learning about motorcycling can be a lifelong pursuit. Get to know others traveling the same road. Be sure to stop by our Motorcycles Forum where thousands of motorcycle addicts read and post messages daily discussing their passion for motorcycles.

Basic Motorcycle Tips for Beginners

Beginning riders often have no clue as to what else they need to buy after they have purchased their first motorcycle. It turns out that the list is quite long. Here are some essentials that you need to have with you as you ride. Lots more can be added later as you increase the size of your bike. Of course you still need to find places to store all the extra items. That's why people end up with big touring bikes pulling trailers or rat bikes piled high with junk festooned with multiple interlocking bungee nets.
