Customer Reviews

Worth every penny!

I just finished it. Great detail but not too much. Most difficult math is a bit of geometry. I especially liked how he gives you eyeball starting points for various things based on years of dyno testing different bikes. I would love an updated version with discussion of newer technology like detonation counters, etc. I plan to get his other tuning books.

An absolute must have!

If you are planning on doing any modification to your 2 stroke, this book is a must have. A comprehensive and insightful look into the sometimes confusing world of tuning 2 strokes. This book will clarify 90% of your unanswered questions. Everything covered can be applied to any 2 stroke, as each topic is taken in pricipal, not specifics for each engine necessarily. I have found that i can even apply these things to my 1967 SAAB 2 stroke. It is easy to understand and follow even to a 15 year old novice like me! I couldn't live without this book. . one of my bibles!

Removes the Mystery from the 2-Stroke GP Engine

An excellent academic book on the theory behind performance tuning for 2-stroke motorcycles. Geared specifically for GP and Kart racers, this hardcover treasure has turned out to be a great reference source for questions on the logic and concepts that pertain to tuning a 2-stroke for maximum performance. This doesn't always mean maximum horsepower. As is stated by the author, every great 2-Stroke racing machine is a compromise of power -vs- function. This concept alone makes the book well worth the purchase price. A "must-have" if you race a 2-stroke, especially a Yamaha TZ250 or 125. Includes tons of pictures, charts, graphs, comparisons, numbers. formulas, theory, examples, stories, and more!

Great Book on Understanding Two-Stroke Racing Engines

Excellent primer on understanding the workings of two-stroke engines for racing. If you are a novice/beginner then this book is for you. There are only a couple books like this ever made and that makes this one well worth the money. I learn a little more every time I read it.

the best "how to" book I own

A Graham Bell Gives you what you're paying for; his expertise, advise, and experience. He provides results of his own experiments, formulas, and rules of thumb. I have been very happy with this book, and I am still riding the result!
