Two-Stroke Performance Tuning - Second Edition

By: A. Graham Bell .

The two-stroke engine has been developed to a degree that was thought impossible not so many years ago. One of its virtues is that it is mechanically very simple, which is a contributing factor to its widespread use and varied application. However, this apparent simplicity has fooled many would be tuners into believing that this type of power unit is easy to modify. While an engine can soon be improved, it is all too easy to go too far and end up with a unit that is actually slower than its stock counterpart!

In this book the author takes you through the various modifications that can be made to a two-stroke and its components to give maximum usable power output and mechanical reliability.

All areas of the engine operation are explained and analyzed, from air and fuel, through carburation, ignition, cylinders, porting, reed and rotary valves and exhaust systems to cooling and lubrication, dyno tuning and gearing.

This book is an essential workshop companion for anyone in developing and enhancing the performance competition engines.
