The 10 Worst Handling Motorcycles of All Time
Some motorcycles just handle badly! But which classic bikes make the top ten for worst handling bikes of all time?
Motorcycle Engine Rebuilding, the Basics
Rebuilding a motorcycle engine can be very easy (a single cylinder 2-stroke) or complex (a multi-cylinder 4-stroke). But the same basic rules and procedures apply, regardless of the type or size. However, the sequencing for doing an engine rebuild is very important to the ultimate success of the project.

Polishing and Buffing Motorcycle Engine Cases
There are few more satisfying tasks when restoring a classic motorcycle than buffing and polishing the engine cases. With some basic tools, and a few hours work, the surface on a case can be transformed into a chrome like finish.
Motorcycle Frame and Engine Numbers
For information about a specific make or model of a motorcycle, the owner must have the frame (chassis) and engine numbers. Locating a frame number on an early machine, especially one that is dirty and in need of restoration (barn fresh for example), can be challenging.
What's a Bobber and Why Do Some Motorcycle...
Done properly, a bobber is a motorcycle that has had unnecessary components removed (unnecessary in the opinion of the owner) and is styled to the owner’s taste—no rules.

Setting Motorcycle Valve Timing
Knowing the timing system before disassembling or reassembling an engine is critical, but one aspect of timing comes before all others: crankshaft position.
Why a Motorcycle will not Start
There are many individual components on a motorcycle that can, if broken or damaged, stop the engine from starting. But in essence, an internal combustion engine needs three things before it will run.
Classic Bike Ignition Systems
There are two common ignition types associated with classic bikes: contact points and fully electronic. One of the shortcomings of the contact point ignition system is the tendency for the heel on the points to wear, which has the effect of retarding the ignition.
Problems Starting a Motorcycle After Storage
There are number of items that can cause a motorcycle not to start after being in storage. We take a look at some of the common problems, and what to look out for after storing a motorcycle.
Kawasaki Triples
The Kawasaki three cylinder 2-strokes were unique motorcycles. For street bike performance, the H1 was unrivaled; at least as far as acceleration was concerned.
Making a Motorcycle Wiring Harness.
Replacing the wiring harness, or loom, on a motorcycle is a relatively easy task but can be time consuming.
Motorcycle Storage – Winterizing Your...
For many classic bike owners, winter is the time to do essential repairs or maintenance. However, winterizing the bike first is a high priority.
Painting a Motorcycle Fuel Tank
Of all the paint finishes on a motorcycle, the fuel tank is the one that most people will be drawn to. It is, after all, the most prominent item on a motorcycle. In the case of a motorcycle restoration or in a situation where a fuel tank has received damage in an accident, the tank should be repaired and resealed on the inside first.
Classic Motorcycle Wiring
To completely rewire a motorcycle, the owner or mechanic must have considerable previous experience, or at the very least, the ability to read a schematic wiring diagram. That being said, it is a relatively easy task.
Motorcycle carburation - Just what is a Rich or...
For an internal combustion engine to run properly it needs three things: gasoline, air (compressed), and a spark. However, having the gasoline/air mixture ratio right is very important for performance: too rich or too lean will affect the performance.
Classic Motorcycle Frame Welding Types
The early bicycle frames used the lug construction method of frame assembly. Later motorcycle frames used various welding types including brazing, shielded metal arc, MIG and TIG to join the various tubes.

For all mechanics, learning how to undertake mechanical work must be done in stages; it starts with basic jobs and progresses, as the knowledge base increases to more challenging work.
How to Make a Motorcycle Cable
Making a motorcycle control cable is relatively easy and requires few tools. If the cables are to be made from scratch, the mechanic must first establish the length of the outer cable. Page 2.
Swapping Motorcycle Engines
Motorcycle engine changing, or swapping, has not been limited to café racers. Many motorcycle owners have created their own versions of the ideal motorcycle by replacing the stock power unit—some out of necessity, some by choice. However, although it sounds simple to do, fitting an engine into another manufacture’s frame is not easy and there are many safety implications to consider first.
How to Restore a Motorcycle
Restoring a classic motorcycle seems like fun, on the face of it. It is, however, a long process requiring dedication, organization, mechanical skills and some tooling. But, for the most part, it is not beyond the average owner with good mechanical skills to restore a classic motorcycle.
Which is Best, 2-Stroke or 4-Stroke?
The main advantage of the 2-stroke was its power to weight ratio and its reduction in moving parts compared to the 4-stroke. Alas, with emission legislation getting tighter all over the world, the days are numbered for the 2-stroke.
Carburetor Balancing Using Vacuum Gauges
Carburetor balancing on multi-carb, multi-cylinder engines is very important. The most accurate method of balancing these types of carburation systems is by using vacuum gauges. When attached to the inlet systems, the vacuum gauges measure the amount of vacuum drawn on each gauge as the engine is running.

Motorcycle Wheel Building
Although the job of replacing rims and spokes on a motorcycle wheel is somewhat complex, it is not beyond the competent home mechanic.

By far the most popular clutch design is the multi-plate layout. Depending on the rider and type of riding he or she does, most multi-plate clutches will last for many thousands of miles. Typically, the first indication that the clutch is in need of maintenance is when it slips under heavy acceleration.
Classic Motorcycle Exhaust Systems
Classic motorcycle owners are unlikely to have problems with noise outputs as many countries exempt older machines from the current laws. However, to keep a motorcycle period correct, classic restorers must ideally find NOS (new old stock) items or modern replicas for their machines.
How to Maintain and Adjust Drum Brakes
Many classic motorcycles use drum brakes. These simple, reliable brakes have been around since the beginning of motorcycling. Adjusting and maintaining them is also relatively simple.
First Time Riders on Classic Motorcycles

Measuring the amount of wear on pistons and rings is relatively simple (once an engine has been disassembled) and requires few tools, primarily a feeler gauge.
Five Things not to do When Braking on a...
Motorcycling is not without its dangers and incorrect use of the brakes can make it a whole lot worse.

Motorcycle Trials for Vintage and Classic Bikes
Motorcycle trials were one of the earliest forms of competition for motorcycles. The courses generally consist of a number of sections laid out on natural terrain. Each rider must complete the sections without stopping, or placing his feet on the ground.
Motorcycle Handlebars
The choice of the handlebars for a motorcycle can be purely personal. The selection is vast, from clip-ons to ace bars and ape hangers, the aftermarket offers many choices besides stock items.

Villiers Motorcycles
Thanks to the recommendations of Frank Farrer, Villiers 2-stroke engines have powered many different classic motorcycle manufacturers’ products, and everything from lawn mowers to milking machines.
Cafés and Motorcycles in the 1960s
During the 60s in England, the youth of the time fell into one of two subcultures: mods or rockers. Home base for many of the rockers was their local café. What had once been a small café supplying transport drivers and local factory workers, blossomed during the 60s into a meeting point for hundreds of motorcycle riders.

All about Motorcycle Fairings
Regardless of the type or style of fairing being fitted to a motorcycle, the same basic rules apply.
Right or Left Side Gear Change Levers
Learning to ride a motorcycle with the gear change on the opposite side to what a rider is used to takes time and practice. However, once mastered, it will allow the rider to transition from one system to the other easily.
Yamaha RD/RD500

Motorcycle Handling Problems
For the classic bike owner with a motorcycle that does not handle well, there are some changes (even modifications) that will improve the handling of his machine. However, before making any changes, it is very important to establish what is causing the handling problem and in particular when did it start?
