Cable Routing
Correct cable routing is a very important part of classic motorcycle safety. All cables, wires and lines were designed to follow a specific route.

Motorcycle Carburetion – Rich and Lean Mixtures
An internal combustion engine needs three things to operate: gasoline and air (compressed), and a spark. Optimizing the combustion is the tricky part. The spark must occur at exactly the right moment, and the gasoline/air mixture and ratio must be in the correct proportions, neither rich not lean.

Fine Bead Blast Finish
Trying to keep a classic motorcycle looking original during a restoration can be a challenge. This is particularly true when it comes to finishes on engine cases, for instance.

Drilled Rotors
Although drilling rotors will often make a classic motorcycle look period correct, the owner must consider the safety implications if the bike is to be ridden on a regular basis.

First Time Riders on Classic Motorcycles
Riding a motorcycle for the first time is often exhilarating and terrifying at the same time. If the bike happens to be a rare classic, the owner will be very nervous too. But there are some basic riding rules that the first time rider must adhere to that will alleviate some of the potential problems.

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 Motorcycle Tools, Air Powered
At one time, air tools were used only by professional shops or race teams, but today, anyone with a workshop should consider using them.
