Unique Motorcycle Helmets

There are many ways that you can have your own novelty motorcycle helmet. There are many shops that offer you a selection of novelty designs that you might find very attractive indeed. If this fails, you can always have one custom made for you. You can have a certain design for a helmet in your mind and you might want to have one. The best thing for you to get one is by having one custom made. That way, even your choice designs are made to your exact specifications, giving you a helmet that looks and also feels good on you.

Once you have your own novelty motorcycle helmet to use, you should be able to know how to take good care of it. Such motorcycle helmets may be tough and sturdy but they should be handled as a fragile item. In cleaning your helmet, try using only the mildest soap recommended.

Avoid using petroleum-based cleaning fluids and agents on your helmets as they can cause the protective layer of your helmet to decompose. Try not to drop your helmet on hard surfaces. A dent on your helmet would be enough to cause you discomfort when you wear it and its safety and protective properties may be compromised.

Do not store your novelty motorcycle helmet near gasoline, cleaning fluids, or in places with excessive exhaust fumes and heat. Materials that make up your motorcycle helmet may react chemically in such environments and may be invisible to the naked eye.

Read instructions carefully about painting or decorating your helmet. The material composition of your motorcycle helmet can change if painted or applied with decals. Try also to avoid hanging your motorcycle helmet on your side mirrors, turn handles or sissy bar. This can damage the inner liner of your helmet which can make it unusable after a short time.

Try to follow these tips to ensure that your novelty motorcycle helmet continues to provide you with the comfort and protection that it was designed for. Care and awareness is important in prolonging the life of your helmet.

If you have read the HowStuffWorks article How Car Engines Work, then you know how a basic four-stroke gasoline engine operates. A piston goes through the intake, compression, combustion and exhaust strokes every two revolutions of the crankshaft. When your lawn mower is idling, you can hear the pop-pop-pop-pop sound of the individual strokes. What you are actually hearing is the sound of the compressed gases in the cylinder escaping when the exhaust valve opens. Each pop is the sound of the exhaust valve opening one time, and it happens on every second revolution of the crankshaft.

In a two-cylinder, horizontally opposed engine, the pistons are timed so that one fires on one revolution of the crankshaft and the other fires on the next revolution -- so one of the two pistons fires on every revolution of the crankshaft. This seems logical and gives the engine a balanced feeling. To create this type of engine, the crankshaft has two separate pins for the connecting rods from the pistons. The pins are 180 degrees apart from one another.

A Harley engine has two pistons. The difference in the Harley engine is that the crankshaft has only one pin, and both piston rods connect to it. This design, combined with the V arrangement of the cylinders, means that the pistons cannot fire at even intervals. Instead of one piston firing every 360 degrees, a Harley engine goes like this:

• A piston fires.
• The next piston fires at 315 degrees.
• There is a 405-degree gap.
• A piston fires.
• The next piston fires at 315 degrees.
• There is a 405-degree gap.

And the cycle continues.

At idle, you can hear the pop-pop sound followed by a pause. So the sound of a Harley is pop-pop...pop-pop...pop-pop. That is the unique sound of a Harley-Davidson motorcycle.
