Running Your Pit Bike Engine For the Very First Time!

This article concerns everyone who just bought a pit bike online and are wondering what to do after assembling it!

Most manufacturer manuals and other sources will tell you the same thing about running the engine for the very first time:

Do not run your bike at more than two thirds of its full throttle and avoid high rpm’s during the first two hours of running. Often you are advised to drain the oil AFTER these two hours and use quality semi synthetic 10W40 4-stroke engine oil.

Because I just got myself a two new ssr pit bikes , I was browsing a very reputable pit bike forum (pitbikeclub.co.uk) looking for some info on assembly and breaking in and I stumbled upon some VERY valuable info. This article is a short summary of a newsletter article I found written by Motoman. Motoman is a very experienced superbike tuner who has his own newsletter (Power News Magazine).

This article “Break-In Secrets” is very controversial.

“Links to this article now appear on hundreds of motorsports discussion forums from all over the world. The reason is that over time, large numbers of people have done a direct comparison between my method and theowner’s manual method, and the news of their success is spreading rapidly.”

“The results are always the same… a dramatic increase in power at all RPMs. In addition, many professional mechanics have disassembled engines that have used this method, to find that the condition of the engine is much better than when the owner’s manual break-in method has been used.The thing that makes his page so controversial is that there have been many other break-in articles written in the past which will contradict what has been written here.”

Motoman wrote “break-In Secrets” after successfully applying this method to approximately 300 new engines, all with great results and no problems whatsoever. So I advise you to consider his advice!

According to Motoman, by just following the instructions from the manufacturer, you risk a permanent loss in power of about 2 to 10 percent. The direct result from a too gentle break-in will be leaky piston rings. This will allow pressure to blow by into the crankcase on acceleration, and to suck up oil into the combustion chamber on deceleration. In other words: loss in power and permanent contamination of the engine oil. The only solution to a bad break in will be: re-honing the cylinders, installing new piston rings and starting over again. In other words..you will have to take the engine apart!

You only get ONE chance to break in your engine correctly! I will explain you why and how.

Correctly breaking in your engine is all about the piston ring seal. A correct break in will result in a better fit of the piston ring against the cylinder surface. This will prevent leaky pistons. New rings  must be worn in quite a bit in order to seal all around the bore. If the gas pressure is strong enough during the first miles of operation (open that throttle!), then the entire ring will wear into the cylinder surface, to seal the combustion pressure as well as possible.

So what is the problem with a too easy break in?

The honed crosshatch pattern in the cylinder bore acts like a file to allow the rings to wear. The rings quickly wear down the “peaks” of this roughness, regardless of how hard the engine is run.There’s a very small window of opportunity to get the rings to seal really well … the first 20 miles! If the rings aren’t forced against the walls soon enough, they’ll use up the roughness before they fully seat. Once that happens there is no solution but to re hone the cylinders, install new rings and start over again.

SO…the best advice i found about breaking in your engine is

1)Run it hard! (for specific methods: breaking in on a dyno, on the streets or on the racetrack…check Motomans 14 page article!

2)DONT use synthestic oil! Refresh your oil immediately when receive the bike, BEFORE breaking in, as you cannot be sure about its quality. Use Valvoline, Halvoline, or similar 10W40 petroleum CAR OIL. Cange oil and oil filter after first 20 miles!! After two days of hard racing you can change to your favorite brand.  Check the article to find out why.

Reducing The Chance Of Delamination In 50mm Clincher Wheels Made Of Carbon

To meet the needs of a variety of types of terrain when cycling, 50mm carbon clincher wheels usually fit the need quite well. This type of wheel is also simple to use for a rider because of the features they’re designed with. Some of these features help with lessening delamination, which is something that is not uncommon with this type of wheel.

Lessening The Risk Of Delamination

It is a given that wheel manufacturers pay close attention to what types of failure can come about with a particular material they are using. It is unfortunate, but risks are a fact of life for any type of material used for bike wheels. Carbon clincher wheelset manufacturers have made the effort to develop ways to lessen the chances of failures with these wheels.

How Delamination Is Reduced

– First, the braking mechanism has been moved away from the rim of the wheels as a way to cause less damage brought about by heat. Intensive cycling conditions can cause overheating, which can sometimes bring about fiber delamination.

-To help stop overheating that is created by braking, manufacturers add crushed basalt to portions of the braking mechanism. Rims are designed to have a smooth surface that is often sealed with a high gloss finish in order to decrease the amount of friction that occurs. Reduced friction is known to stop the possibility of rims overheating.

Fortunately, carbon wheels typically incur damage under exceedingly intense riding conditions. Carbon wheels are regularly used on a variety of types of aircraft, and the aircraft industry is known for having very high safety standards. Boeing 787 Dreamliners are manufactured with a little more than 45 percent of composite materials. Carbon laminates make up the bulk of the composite material. Aircraft typically go through a large amount of stress during operation, and this fact is a good indicator of just how strong carbon fiber is under stressful conditions. This also shows that a bike wheel made of carbon is a smart idea.

The following information will further explain what exactly can happen when carbon material is used in conditions that bring about damage from heat. While carbon fiber is considered a strong material that can withstand a high amount of heat, it can still be damaged in conditions that are extreme. Intensive impact and repeated stresses are known to cause the process of delamination to occur. Separating layers can come about due to stress, which makes the material far less durable.

Delamination typically occurs inside of a material, rather than showing on the surface to the naked eye. If you have found yourself wondering if the carbon wheels on your own bike have incurred any damage, you can check this yourself. Listening to the sound the carbon material makes for an easy test. Carbon material that has not been damaged makes a sound that is noticeably vibrant. Materials that have been damaged will often make a much more dull sound.

Having a substantial crash on a bike is a good reason to purchase new bike wheels. This is because a serious crash occurring along with braking over a long term can often cause damage to a frame.

It is a fortunate thing that delamination is typically not a problem under regular conditions of use. Manufacturers work hard to offer a product that allows riders to use their product with little quality troubles when used under normal conditions.

Montague Paratrooper – The Tactical Folding Mountain Bike

Montague Paratrooper Tactical Bike

About:

The Montague Paratrooper is a bit of a puzzle. It's basically an all round commuter bike with mountain bike capabilities however with a name like 'Paratrooper' it comes with the burden of expectation. The marketing people would have you believe that air force troops are embarking on missions with this folding bike as a necessary tool. It may be good for commuting to and storing in the office, with some weekend trail riding thrown in, but I've severely hard risk my life on this particular model without some serious upgrades.

Pros:

-This multi-purpose folder has a sturdy frame that provides both comfort and stability on road and trail.

-The 'Trooper' really looks the part with a rugged military appearance and top of the line design (unique patented seat tube folding system) and will raise your street credibility quickly.

-It's not just cool, it's convenient too. This bike folds in 30 seconds without tools, is light enough for the train, and its standard parts are serviceable at any bike shop.

-An added bonus is great support from Montague who are known to compensate customer effort with extras such as folding pedals.

Cons:

-This bike is not heavy (aluminum) however it carries the weight of reputation; having to live up to its image as 'tactical' is too much to expect from a bike that is overpriced by at least $ 100 yet fitted with cheap, low-end, and sometimes generic components.

-The major downfall of this bicycle notwithstanding the sturdy frame is durability, or a lack of it, as the parts / fasteners bend and warp easily and are non-corrosion resistant.

-It's not uncommon to replace the gear sets, shifters, pedals, shocks and cranks on this mountain bike.

Recommended:

Yes, if you are willing to surround a solid frame and leading-edge folding design with self-tailored custom hardware and do minor repairs yourself. Remember to shop around for a good deal then replace standard components with your own specialized equipment and you're ready to ride.

Simple Bicycle Tire Sizes Buying Guide

In buying replacement tires for your bicycle, it is very important that you know about your options when it comes to bicycle tire sizes. There are many factors to consider aside from the bicycle tire sizes, such as the type, durability and brand. At the end of it all, you would want the right fit for your vehicle and for your frequent style in terms of riding such.

Different Tires for Different Bikes

The standard bikes that are used by adults, such as hybrids and mountain bikes have tires that measure 26 to 27 inches in terms of the outside diameter. BMX typically uses bike tires that measure 20 inches. Racing bikes, on the other hand, measure the tire sizes in metric. The most common bicycle tire sizes for the road or racing types of vehicle is 650 mm or 700 mm.

The width is also very important in measuring the kind of bicycle tire sizes that you need. For the hybrids and mountain bikes, the typical measurement that would include the width is 26 x 1.5 inches. In this case, 26 is the diameter and 1.5 is the width. Road bikes commonly measure 700 x 23 mm. These vehicles are fit for racing and high speed mode of riding that is why the width is slimmer than the other kinds of bike tires. For beach cruiser bikes with balloon tires, the most common measurement is 26 x 2.125 inches.

Strength

If you do not have much experience in many types of bicycle tire sizes, you need to get other people's view and feedback about the materials that they have already tried. There are many brands that cater to this need, and all these specialize on certain aspects. You have to make sure that you will be getting something that can withstand the kind of roads where you will use the bike. There are even some models that you can avail with extra features and added reinforcement to make the tires resistant to punctures.

About the Tread

You have to be specific in choosing the kind of tread that you want for any bicycle tire sizes. For mountain bikes, you have to look for treads that are knotby. These will help the bike trail through wet and muddy paths. If you are using race bikes, you have to get tires with smooth treads that have minimal contact with the ground. The smooth tread pattern is best suited for everyday use, especially if you are often riding the bike on pavements.

In buying tires for your bikes, you have to know exactly what type do you need and which will best suit the kind of riding that you do often.

Examining Different Mountain Biking Terrain

Mountain biking has become a popular sport and recreational activity for a lot of people. An important factor for most mountain bikers is the terrain they ride on. While most riders prefer riding on rough and dangerous terrain, it helps to understand the characteristics of each of these terrains. Mountain bikes are chosen keeping the terrain in mind and are usually strengthened by using better materials and also sport larger tires for the added support. The terrain also makes claims on the biker's skills and talent, as not all terrains are suited for the average rider.

Cross Country

Cross country is the most popular mountain biking choice. This is a combination of different terrain types. It includes hilly surfaces and loops. The course is outlined in some cases. In some places, riders also have races on these outbound courses. The Scott Scale 60 is a perfect choice for this terrain.

Downhill

Downhill mountain biking is among the most dangerous terrains that mountain bikers. Most often, ski resorts in the summer as used as downhill cycling track. The terrain is usually mapped so that the riders have to maneuver around various obstacles and rough terrains. This terrain needs riders to be experienced and should sport the right protective gear. A Scott Scale 20 or a Scott Scale 29 would be ideal choices for bikes for this terrain.

Freeride

The name suggests that it is a combination of all forms of mountain biking. It contains a good mix of downhill cycling tracks and some trails and loops. The terrain has been rough and is generally recommended for experienced riders who have demonstrated skilled riding in other downhill terrains.

Dirt Jumping

Dirt jumping involves riding up a mound of dirt and landing successfully on the other side. It also involves performing stunts on your way to the other side. If you are a novice rider or just a hobbyist, this is not the right terrain for you.

Trials

Trial riders jump over obstacles of varying sizes using their bikes. This is viewed on par with skateboarding where the scoring lays emphasis on creativity and style.

Mountain bikers keep their terrain in mind while choosing their bikes. Recreational riders could go in for bikes like the Scott Scale 29. These bikes have sturdy frames and fairly good suspension forks. This helps in improving the ride quality. These bikes are commonly used for commute in most cities and are easy to ride. These bikes are perfect for people who would like to go cycling with their entire family.

Mountain biking has evolved over the years. Mountain bikers now have a variety of bikes to choose from. The bikers also have easy access to the best gear and parts for their mountain bikes. However, newer riders should understand the risks involved and should know where to draw a line. A lot of injuries occur while performing stunts or while hurtling down a very tough hillside. People who wish to enter this sport should spend some time researching and understanding the terrain that they are best suited for and get them the best gear and equipment.

Types of Specialized Bikes

Specialized is a world renowned brand in the cycling world. Their bikes have been used by the world’s best riders to compete in some of the world’s most prestigious biking championships. Some of these championships include the Liege-Bastogne-Liege, the Paris Roubaix, and the XC World Championships. They’ve been around for a long time, and just get more innovative with age. Every bike is specifically designed with the comfort and efficiency targets of the consumer in mind. The bikes range from designs for serious professionals and semi-professionals like the S-Works Tarmac SL3 2011, and the Specialized Rockhopper & Stumpjumper respectively, right through to bikes for commuters and casual riders like the Allez 16 2011.

This article aims to help clear up any confusion about who Specialized are and the three different designs of bike they do:

  • Racing bikes – The Specialized S-Works Tarmac SL3 2011 is designed for maximum efficiency and racing power. The S-Works brand is well renowned across the world for its connotations of excellence and record breaking aggressive performance. S-Works bikes are also very lightweight and extremely fast. The Tarmac is no different, because it has an oversized BB, you can pedal at maximum level. It also comes with a FACT 11R Carbon frame, Roval Rapide SL wheels and Shimano Dura-Ace 10 Speed!
  • The road bike/commuter – Specialized also design bikes for less extreme use, the Allez is engineered for the everyday rider who wants the distant feel of the road race scene in the speed and efficiency of the bike, but also wants that everyday element.
  • The everyday bike – not everyone cycles to work or rides in the Paris Roubaix, sometimes you need something to get you about in style without breaking the bank or compromising on quality and efficiency. The Specialized Rockhopper 2011 is a bike that caters to this market perfectly. Whether it be a quick ride to the shops or a Sunday ride in the country, the Rockhopper will do just about everything

Motorcycle Gear For Your Dirt Bike

When you start riding, you may choose to go with a dirt bike. This is a great idea but you should know that they are as fast and maybe a little faster then the street bikes that you may see running around town.

When you start looking into dirt bikes, you may notice a wide range of motorcycle gear for this kind of bike. This is because many people like to ride this kind of bike and even more people like to race them. They like to go fast and these kinds of bikes are really for those that want to go fast and jump their bikes off road.

When you go to the motorcycle gear shop, you may notice that there are a lot of different colors and designs that you may pick from. These times are covered in patches that represent each different team, if you are on one or rooting for one certain team. These shops can be found in small and large towns as well as on the interstate, if you are going on a long trip with your bike in tow. Most dirt bikes are not allowed on the street if they do not have a headlight or a tail light on them, so you might want to keep this in mind if you are going to want to ride on the street.

When you are ready to buy your motorcycle gear, you may want to keep in mind that you are going to need to match your bike. This is so you will look good when you are riding the motorcycle and people will know what one you are in races. This is, of course, up to you but many riders try to have the same colors as their bikes at the very least. Motorcycle gear for your dirt bike is really not that hard to come by. There may even be local shops that carry it and will help you pick the right one for you.

Take some time so that you will be able to find the motorcycle gear that fits you and your chosen style, even while you are on the racetrack so that you will look good and go fast at the same time. You never know who will be watching and what they might think about you and your motorcycle gear as well as your racing skills.

Ground Breaking Software For the Used Motorcycle Parts Industry

Greetings to all, this is the first installment of topics concerning the Powersports industry. This article is in response to articles we have read out there concerning used motorcycle parts. My family owned and operated a motorcycle shop for over 10 years. We were and independent shop and sold almost every brand out there. We also go into the salvage side of the business and purchase damaged bikes from insurance companies and sold off remaining undamaged parts on the vehicles.

This industry boomed for the past 5 years and as most enthusiasts know you now have TV shows on customizing, building your own bikes, and even restoring them. Now the feature concerning our article today is the used parts aspect of the industry. Now almost everyone knows the terms bone-yards, junk-yards, salvage yards, etc. And when we here these almost everyone thinks of the automotive industry. This parts recycling business has been around since the productions of vehicles. The Powersports industry however never had a prominent foot hold in this aspect of the industry, until now.

I would like to refer to a ground breaking company bringing these hard to find motorcycle salvage yards together to one meeting place and show in real time what parts they have in stock. (We have referring links to these sites below.) The company is called Salvage Dealer Link. They are an Internet based software company that stores all subscribing dealer’s data in the system by original part number. The ingenious software used an interchange system to tell you the consumer which dealers have the parts in stock, how much they are asking for the part, how far they dealer is from you, and even let’s you know if a dealer has the part you need, even if it’s off a totally different bikes. Wow, that a lot of service the offer you in one simple search. And that is just the tip of the iceberg.

But today we are focusing on the used parts feature they offer, and how these parts are handled. Dealers enter these parts with a point click selection method to keep consistency in the database. And in return they made it just as simple to search for the parts. You simple select year, make, model and then select the part you are looking for. You don’t have to worry about misspelling or not finding the part because you are searching with different terminology than the dealers. And just to top of the searching experience, all data is real time, no more filing out a parts request form that gets sent who knows where and waiting days or even long for a reply. If a dealer has it, you see it instantly. And best of all, if many dealers have it, you can compare pricing, condition, age of parts and even find the closest dealer to you. They will also be launching version 2.0 in a few weeks and individuals like yourself will be able to open a free account to track your favorite searches and keep an eye out for those hard to find parts.

New Or Used Motorcycles: Which Is the Right Choice for You?

When deciding between new or used motorcycles, how do you decide which is right for you? On the one hand, a new bike comes with fairly iron-clad guarantees of reliability. On the other, used motorcycles tend to require far less initial cash outlay. Which is the right choice? The answer depends on a few factors.

Price is a deciding factor for many riders. Once a new bike rolls off the lot, depreciation sets in, making a used vehicle a sensible choice, strictly in terms of impact upon the wallet. Simply stated, the price for last year’s model is likely to be far lower than the shiny new rides on the showroom floor. With a small sacrifice in terms of bells, whistles, and the latest technology, it may be possible to buy a higher quality bike than one could otherwise afford. It’s important, however, to weigh the total cost. Used motorcycles show the wear and tear of having been ridden. The bike that seems like such a great deal might, in fact, need a lot of work, or be due for major maintenance. If you are not an expert mechanic, it may be wise to buy from a dealer, who has a vested interest in ensuring that the bike is at least mechanically sound. They may hope to build trust with customers who will then return for maintenance, repairs, and accessories.

A rider’s personal mechanical ability comes into play when deciding between new and used motorcycles as well. Most riders are enthusiasts, and many have tinkered around with engines, at least to some extent. Not all riders, however, have the knowledge to spot a bike that has been laid down, causing a bent frame, or know the signs of a hog that has been ridden hard and poorly maintained. An honest assessment of your own ability, willingness, time, and resources is necessary when considering a pre-owned machine. Are you willing and able to perform repairs? Do you have the resources necessary to replace parts, carry out necessary repairs, and recognize signs of damage or wear?

Finally, it’s wise to consider the future. Buying used motorcycles through classified advertising or online sales sites is always risky, but a savvy buyer may choose to go in that direction if a particularly good deal presents itself. It may be prudent, however, to consider buying from a dealer, whether you decide upon new or pre-owned. You will have the assurance that the bike has at least been looked over and assessed for wear, tear, and the potential need for repairs. Most dealers offer more than just motorcycles. They’re an excellent resource over the long term, whether you need maintenance, repairs, accessories, or just advice. The riding culture is built upon relationships. Building a solid connection with a local dealer not only supports the community as a whole, it provides you with a valuable resource for help down the road. Whether you buy new or used, make sure to buy the ride that’s right for your needs.

Types of Motorcycle Frames

If you are going to build a motorcycle, the frame determines the basic look of the bike. Of course motorcycle frames affect not only the appearance of the bike but the handling and safety of the finished machine.

Frames are the basic skeleton to which other components are attached. They hold the motorcycle tanks and engine and provide support to the whole bike. Most frames are made of steel or aluminum but there are also other choices such as carbon-fibre.

Motorcycle frames generally fall into one of several categories.

Single Cradle: This is the simplest of the motorcycle frames, a design that harks back to some of the earliest motorcycles ever made. It has a single large tube for a spine and smaller tubes that cradle the engine. This is commonly used on off-road bikes. A variation is the split single cradle which is a single cradle that splits into two cradles at the back for the exhaust.

Double Cradle: An evolution of the single cradle, it uses two cradles on either side to hold the engine. These were commonly used on simple road bikes and some custom bikes, but have mostly been supplanted by perimeter frames.

Backbone: These are specialty frames that are used rarely. It has a solid metal backbone and the engine hangs suspended from this. It’s a simple and inexpensive frame with a distinctive look, but other designs are better in terms of strength and rigidity.

Perimeter: These frames originated on racing motorcycles. The steering head and swingarm are joined at a very short distance, reducing flexure and torsion substantially. They were originally made from steel but most are made from aluminum nowadays to save weight. Once the advantages of this frame were seen, they were adopted by most motorcycle manufacturers.

Monocoque: Another specialty frame that is even rarer than the backbone. They are very heavy and rigid, combining seat mounting, tank, and tail into a single sturdy piece of metal. They are used almost exclusively on specialized competition bikes and are not a good choice for street bikes.

Trellis: European manufacturers came up with this design although it is catching on in the US as well. It uses many of the same construction principles as the perimeter frame and matches it in rigidity and weight. Its distinctive look is formed by a “trellis” of short tubes that make up the body of the frame. It requires more effort to manufacture than the perimeter but the result is extremely strong.

One of the earliest decisions to make is which of these motorcycle frames is right for your bike. Many of your other decisions will depend on the type of frame you choose so consider the options and choose wisely.
