Go-Kart, an Italian passion

With the recent success of Ducati Corse in the World Motorcycle category "Moto GP", engines made in Italy have shown, together with the "custom" Ferrari, to be designed to be regarded as leaders around the globe.

Indeed, a bit like in all other areas, the Italian manufacturing presents as well as a high quality product also the passion and determination that distinguishes us in achieving excellence and objectives.

In this regard, even in Go-Kart production Italian companies are moving and promoting all over the world, thanks to a great go-kart production using the best engines, components and accessories.

But perhaps this fascinating world of competition with mini-cars, called Kart or Go-Kart, is not well known and less popular because of the two sports quoted above: motorcycle and Formula One.

Indeed, karting is the simplest form of motorsports run with small cars with essential shape: tubular steel frame without suspension, wheels and engine. The sport, just for fun transmitting in goal, was born as a hobby but now is a step "almost mandatory" for those who wish to embark on a career as a professional pilot. Not surprisingly, the latest F1 exited from its "breeding garden" of the go-kart (Schumacher, Senna, Prost, Alonso, just to name a few).

The kart was born in America, as often happens, for economic motivations in 1956 where cars race became increasingly expensive and the number of participants (and especially the audience) was so narrow to seek alternatives. In these terms, the Karting was the dowry of remedy, at least in some respects, this situation by proposing solutions extremely funny but also economic and accessible to all fans of engines.

In Italy the phenomenon develops and explodes in the early '70s where simple manual constructions moved towards specialization of some companies in the production and sales of Go-Kart competition. The first racetracks were born and passion spreads quickly from young to older who do not disdain the emotions that only a sports car like the Go-Kart can feel.

Recently Kart manufacturers have always researched and developed new solutions, improving each component of competition mini-cars with high technology spare parts able to greatly improve the performance and consistency of the same in sports and competition areas.

Finally we have only to indulge in this passion with friends and colleagues in breathtaking races, perhaps without exaggerating for the weak of heart.


Get To Know Your Mini Moto - Part IIII

In the last part of the Get To Know Your Mini Moto series, I will explain how further components of the mini moto contribute to this great little machines.

Throttle

The throttle on your new mini moto is a 'twist grip' style throttle. When you twist the throttle the throttle cable is pulled back revving the engine. It is important to keep this cable free from obstacles and clean. If the throttle begins to feel 'loose' of 'gives', the tension of the cable can be adjusted via the adjusting screw.

Brakes

The brake system comprises of brake levers, brake cables, brake calipers and brake discs.

The brakes on your mini moto are operated by levers found on the handle bars. The right hand brake controls the front brake, and the left controls the back brake. Pulling on the handle pulls the brake cable which in turn pulls the lever located on the bake caliper. This action pushes the brake discs towards each other. This creates friction on the brake disc which slows down or stops the bike.

The brakes can be adjusted in the following ways.

The brake cable can be tensioned using the adjustment screw found on the brake lever. Unscrew the locking nut; twist the screw to reach the desired tension. Re screw the locking nut.

This is a two person job. Adjust the screw on the hand brake so that is at the end of its travel. Undo the clamp that holds the brake cable on the lever located on the brake caliper. One person needs to push the lever forward as far as it will, the second person needs to pull back on the brake cable and re fasten the clamp. The crake cable will now be highly tensioned.

Pull Start

To start the mini moto pull slowly to turn the fly wheel. This pumps some fuel around the engine, which lubricates the moving parts. Pull the pull start firmly in order to start the engine. Important, do not pull the cord to the end of its run as it can break. If the mini moto does not start check the choke and the throttle cable.

Choke

The choke controls the amount of air that is allowed into the air/fuel mix. The choke is adjusted via a lever located on the side and back of the engine. The choke is off when the lever is down, and on when the lever is up. When you start the mini moto the choke should be on, when the mini moto is warm and ready to ride the choke needs to be off.

Carburetor

It is recommended that any adjustments to the carburetor are made by a professional. The carburetor pumps and mixes the fuel and air. The small diaphragms, orifices and ports mix the air and fuel very precisely, this process demands clean fresh fuel.

Jet

The jet can be adjusted by the screw located in the access hole to the right of the choke lever. The jet is adjusted by the manufacture however the conditions of where you wish to ride may be different, which means that you will need to make adjustments. Turning the screw clockwise will make the bike run with a leaner mixture, and counter clockwise will richen the mixture. Only adjust the screw 1 tern at a time and then test the mini moto, this is trail and error. Please note that it is best to find the optimum setting for performance and then run a slightly richer mixture as a mix that is too lean can seize the engine.

Get To Know Your Mini Moto - Part III

This article explains some of the components that contribute to the make-up of the remarkable piece of engineering called the mini moto. Take a read through and discover how each component plays its part.

Air Filter

Your new mini moto is equipped with an air filter. Some bikes such as the B1 Origami rep liquid cooled and the Mini Dirt bike have a 'cone' style K and N style air filter. The 2005 mk2 mini moto and the B1 Origami Replica air cooled bikes have a standard mini moto air filter. Both air filters purify the intake of air that is sucked into the carburetor. This means that the air filter should be cleaned regularly as the mini moto's performance can begin to suffer as the engine can become starved of air if the air filter is choked with debris. To reach the air filter, remove the bikes bottom fairing, remove the protective cover by unscrewing the holding screws. Clean the air filter in petrol but make sure that the filter is dry before reattaching to you mini moto.

Tires

The tires on your mini moto are filled with air (pneumatic). Please consult your mini moto handbook for the appropriate psi. It is important to check the tire pressure regularly, an under inflated tire will affect the performance of your mini moto, acceleration can become sluggish and cornering can become dangerous.

Chain

Before riding your mini moto you need to make sure that the front and back sprockets are aligned and that the chain is perfectly straight running between them. Once you have established this make sure that the chain is tensioned correctly (please see your mini moto handbook). To test the tension of the chain you can manually push the pocket bike, if you hear a 'pinging' or 'popping' sound the chain is too loose. If the chain is noisy and starts to bind the chain is too tight. Make sure that the chain is well oiled. The chain needs to be oiled before every ride.

Gearing

The gearing of you mini moto is dictated by the number of the teeth on the front sprocket and on the back sprocket. The sprockets can be changed as an easy way to manipulate top end speed and acceleration, quite like changing gear on a mountain bike. A front sprocket with more teeth will improve acceleration; however the top end speed will be reduced. A larger rear sprocket will produce a higher top speed but acceleration will suffer. The gearing on your bike can be adjusted in accordance for the track you are intending to ride i.e. a small track with a lot of bends will suit gearing for improved acceleration, however a track with long straights will require a mini moto that is geared for a higher top speed.


Get To Know Your Mini Moto - Part II

The second part of Get To Know Your Mini Moto will delve further into the many components that contribute to a mini moto, namely the clutch and spark plug, and explain how each plays its part in these remarkable machines.

Clutch

The mini moto uses a centrifugal clutch to power the drive the sprocket, which in turn drives the back wheel of your mini moto.

When you start your mini moto the clutch spins as the engine ticks over. The clutch is engaged when you pull back on the throttle. The increase in speed of revolution of the clutch makes the clutch expand and grip the inside of the clutch bell which turns the sprocket that drives the back wheel of your pocket bike.

The clutch can be set up in different ways depending on the type of performance that you want from your minimoto. Adjustable clutches are not standard on mini moto's but an after market Polani or Blata style adjustable clutch can be used in your new mini moto. These allow the rider to adjust the mini moto's set up in according to their preference. Setting the clutch to engage too late when the engine has built up too much power may cause the clutch to slip and never fully engage. This can result in excessive wearing. However setting the clutch to engage too early, before the power has built up in the engine can cause your pocket bike to 'bog down', resulting in slow acceleration. The perfect set up is to get the clutch to engage just as the engine has built enough power to rocket the mini moto away, but without making the clutch slip, this is achievable through trial and error.

Spark Plug

Making sure that your spark plug is fresh is important in a two stroke mini moto engine. You can tell a lot from the color of the spark plug. The top part of your spark plug is covered in ceramic insulator which, when brand new is white. This part of the spark plug can change color according to how your engine is running. The plug should appear as a nice tan color when the engine is running perfectly, this indicates complete combustion. A grayish or white color indicates that the engine is running too lean which can result in engine damage. In this case you should clean and check your fuel system for any obstruction, check your fuel mixture, check for loose intake manifold bolts and carburetor mounting leeks, faulty gaskets and leaking crank seals. Anywhere that your engine could potentially leek and suck in fresh air can be the source of a lean condition.

A blackened or oily spark plug indicates improper combustion and is the result of running too rich. This can be caused by too much oil in the mixture or the spark plug could be faulty and misfiring. Check the fuel mixture and replace the spark plug.


Get To Know Your Mini Moto - Part I

The Mini Moto is a small scale replica of the World Super Bikes used by the likes of Valentino Rossi and ex champion Carl Fogarty. The Mini Moto comes equipped with either a two stroke air or water cooled engine which are, depending on the model, capable of speeds of up to 60Mph. But how much do you know your mini moto? In this part I will underline the finer points of the components that make these speeds possible.

The Two Stroke Engine

The two stroke engine produces more hp per pound than the four stroke engine. The two stroke engine consists of three moving parts, the piston, the rod and the crank. The piston acts as valve that opens and closes the intake and exhaust ports that are located on the walls of the cylinder. Unlike the four stroke engine that fires only every other time of the pistons movement, the two stoke engine fires every time the piston reaches the top of its travel. This means that the time spent generating power is doubled in the two stroke engine than that of the four stroke engine, as there is no engine coasting during passive cycles. This is the main reason that the two stroke engine can rev more highly and produce more power (for its size) that the four stroke.

Fuel

The two stroke engine needs to be run on a mixture of petrol and two stroke oil. This is so that the engine is kept lubricated whilst in use.

99% of all starting problems are caused by fuel problems. These can stem from bad or old fuel and improperly mixed fuel (please see mixing chart). Do not use fuels that contain alcohol, as the can cause you bike to run 'lean'. Be advised some racing fuels contain alcohol and are best avoided... We recommend that you use normal petrol for a garage and quality two stroke oil.

A mixture that is too lean i.e. not enough two stroke oil can damage your mini moto's engine as the moving parts are not properly lubricated. This can cause the engine to seize. However a mixture that is too rich can choke the engine and affect the performance and cause starting problems. You can tell if your mini moto is running too richly by the plumes of white smoke coming out of the exhaust and the lack of performance. A rich mixture (25:1) is needed to lubricate the engine during the 'run in' period; you may experience a lack of performance during this period. The pocket bike may run more slowly and acceleration can be sluggish, however when you change to a mixture of 50:1 you will really notice a difference. The leaner mix ignites in the combustion chamber faster and with a more explosive force than the richer mix. This means higher revs which mean more power and acceleration.

We recommend that a fuel mixture of 25:1 is used to 'run in' you mini moto, and a mixture of 50:1 is used thereafter.

'Running in'

Your mini moto should be 'run in' for the first 3-4 tanks of fuel. During this period we recommend that you use a fuel mixture of 25:1. This means a mixture that is made up of 25 parts petrol to 1 part of two stroke oil. During the 'running in' period be careful to not rev the engine to its maximum as this can damage the engine. The 'running in' period will allow the moving parts to become well oiled and the clutch and brakes to 'bed' themselves in. After you have run the minimoto on this fuel mixture for 3-4 tanks, check the chain and tighten accordingly, check the tire pressure, tighten the bolts on the brakes, forks and wheels. You may also need to readjust the throttle settings to allow for the higher revs that changing to a leaner fuel mix produces. The bike should now be ready for a fuel mixture of 50:1.


German Motorcycle Helmets have a long history

The motorcycle was first developed for every day use in the military during WWII. Along with this development came a lot of the motorcycle gear and motorcycle apparel that enthusiasts still use to this day. One of these style are the German motorcycle helmets.

Fashioned after World War One and World War Two German Army battle helmets, the German motorcycle helmets do not stray far from the original design. There have been other helmet designs based on the original German motorcycle helmet, but this style remains true throughout time.
Being one of the most popular styles today as a motorcycle helmet, the German motorcycle helmet was once only available as a novelty item. It was something to set the extraordinary motorcycle rider apart from the rest of the crowd. Today, there are German motorcycle helmets, that have been approved by the D.O.T. for use in motorcycle riding.

There are no face shields for these types of helmet. They look a lot like the half shell of a turtle. The only other part that sets it apart from a turtle shell are it's colors and the chin strap. Black is a very popular color. Pink German motorcycle helmets can be purchased for the female motorcycle rider as well. Chrome German motorcycle helmets are available and add a certain flair to the helmet.

Carbon fiber German motorcycle helmets are very durable and have a resilience like no other. They can be covered with leather to give them a smooth and semi-glossy finish, as opposed to the shiny black that carbon fiber offers. These can also be adorned with flat black flames that offset the glossy black of the helmet.

When you are measuring for the size of a German motorcycle helmet, use a cloth tape measure. Consider having someone help you to do the measuring. This will ensure that you obtain an accurate measurement. Placing the tape measure about one inch above the eyebrows, and calculating the circumference of your head is the best way to find out the size that you would need. If the measurement falls between two sizes, choose the smaller size. Remember that the chin strap will also help adjust the fit for you as well.

As there are no face shields to the German motorcycle helmet, the motorcycle rider might want to purchase some motorcycle eye protection for their apparel. This is an absolute must on long road trips. The more popular options are yellow, gray, or clear blue tinted goggles. These use a strap around your head and are even more securely fastened in place by the chin strap feature of the German motorcycle helmets.

Whether you prefer leather, carbon fiber, chrome, or simply flat black flames, there is a German motorcycle helmet right for you. The sizes are plentiful, and the originality of the style ensures that you remain a part of motorcycle riding's great history. Purchase one today, and be sure to make the right call and buy the eye protection right for you.


Gas Scooters Safety Rules For Staying Alive!

Gas motor scooters are often thought of as toys, innocent and cheap fun. But it's exactly that type of thinking that can get a gas scooter driver into deep trouble. First and foremost scooters are motor vehicles just like motorcycles and automobiles. They share the road with other cars and trucks and are subject to similar laws and regulations. And although they are an object of desire for many they can be dangerous for the unexperienced or unprepared.

As a general rule gas powered scooters are regulated by state laws as either motorcycles or mopeds and are subject to similar regulations as these other motor vehicles. By staying alert and using caution many accidents can be avoided. Most accidents arise due to carelessness. By paying attention to what is going on around you and what other drivers are doing you can feel relatively safe out on the highway.

There are two things that cause the majority of accidents, speeding and following too closely to the vehicle ahead. Driving safely is all about giving other drivers enough reaction time. If another driver wants to change into your lane directly in front of you it may cause you to lose control if you are speeding and haven't enough time to react. Without enough time to slow down this maneuver by the other driver may require you to move into another lane to avoid him. This can affect other drivers in other lanes which is the beginning of many accidents.

Another major mistake that many gas scooter drivers make is following too closely. When the person ahead of you suddenly slams on the brakes you need enough time to slow down comfortably. Ramming into the back of someone's car is not what you want to do, especially when you are driving a small scooter without any protection around you. By following the speed limits and giving yourself enough room to slow down if something unexpected should happen in front of you most accidents can be prevented.

The third problem arises when gas powered scooters are purchased for use by children and teenagers who do not even possess a valid driver's license. Drivers with licenses may not be any safer on the road than unlicensed drivers, but at least they have had some training and experience behind the wheel of a car. Children and teenagers without any training can be an accident waiting to happen when it comes to motor scooters. Without any experience or training children and young teenagers can quickly find themselves in positions that experienced drivers normally would not.

Kids have been known to throw caution into the wind, darting in and out of traffic without a clue as to the dangers. On gas scooters that are so small they can't be seen well by other drivers, and without much driving experience or training, kids will pose a hazard to both themselves and the other motorists they come in contact with.

Parents should be strongly cautioned to have their children receive the proper amount of training on their gas power scooters before they are allowed onto the busy city streets. Find a deserted road and put them through a training session. The life a parent saves may be his own children's. Only after a parent feels comfortable with his child's driving skills should they allow the child onto the busier streets. By making sure that our children know the safety rules of the road we are decreasing their chances of being involved in a serious accident. Before we can legally drive a car on the highway we must all pass certain tests. Why should it be any different for younger kids?

Gas or electric scooters are wonderful little vehicles that are fun to drive, cheap to buy and are very handy for traveling short distances around the neighborhood to perform errands. They usually have larger storage room than a motorcycle and are very inexpensive to operate. There are many reasons for owning a gas scooter, but in the hands of the untrained and inexperienced they can be deadly.

The ATV, go carts, dirt bikes and mini bikes are other vehicles that are often owned and operated by younger drivers. But they are usually not seen on the city streets as scooters are. Go karts are typically driven on tracks specifically designed for the go cart. And the mini bike, dirt bike or ATVs are typically driven off road. These other vehicles avoid many of the dangers that scooter drivers must face, namely traffic on the busy highway.

Gas scooters are quite popular these days, especially among the younger market who are too young to drive cars yet. Without proper training for these kids it opens the door to possible serious accidents. As the worldwide popularity of gas scooters grows we need to make sure that people's awareness of driving and safety regulations keeps pace, especially among the kids that have no previous drivers experience.

Kids often think of gas scooters as toys, not as potentially dangerous vehicles. But a scooter is not a toy. It is a motor vehicle that is subject to certain laws and regulations. People need to be aware of the potential scooter dangers and remain alert while driving at all times. They should not drive erratically, but be predictable and courteous to other drivers on the road. They should follow the speed limits and remain a safe distance behind other vehicles. Kids should receive proper training before being allowed on the busier streets. By taking these few safety precautions we can help ensure a fun safe driving experience for all.
