It's the 21st. century and two stoke engines are a thing of the past. In the near future they will be OUTLAWED!

But until then. . .
This is an outstanding book for information on 2 stroke air cooled engines. There are plenty of diagrams, charts, and B&W photos that help to explain the text. I am very happy that I got this book for my tech-library before it went out of print. Lots of good tips for people trying to get an extra 10 or 20 MPH out of their old moped or scooter!

This is the best book you can buy on 2 stroke tuning. I have read it 3 times to try and assimilate all the information. If you want to modify a 2 stroke engine, this is the best starting point you can get. Well written, easy to follow and very practical. I have many other tuning books, but this is by far the best. Has up to date information and well worth the money.

I just finished reading the complete book and was amazed at the level of detail and mathematical formulas provided to caluclate just about every aspect of 2-stroke performance.

The book is written more for the racer than the home tinkerer but there are many hints and techniques provided that will help the hobbist to increase reliability and performance of any 2-stroke motor.

I strongly recommend adding this book to your knowledge base.

this is a revised version of his fist book very detailed with tons of pics and drawing great for dirt bikes and go carts i have used it to modifiy my moped. a must have for the super tuner of tinkerer.

This book is fantastic. It explains the intracacies of 2T tuning from the basics to the finer points. This is a great reference full of formulas and tips that can be used while building up a motor.

Anyone into bikes hears lots of opinions on what will make a bike more powerful or faster, but those opinions are usually based on the well known "seat of your pants" meter. This book provides all the knowledge necessary to tune your motor based on a solid foundation of science. The writing is very clear and packed with information. The focus of the book is more on practical techniques that lofty theory.

It's a great how-to guide for dialing in your engine and carb(s), covering combustion chamber shape and size, squish band clearance, porting, and jetting.
