Product Description


Fully revised this book takes the reader through the various modifications that can be made to a two-stroke engine and its components to give maximum useable power output and mechanical reliability. All areas of engine operation are explained and analysed, from air and fuel, through carburation, ignition, cylinders, porting, reed and rotary valves and exhaust systems to cooling and lubrication, dyno tuning and gearing. It includes new material on the latest advances in porting, reed valves, exhaust valve digital controls, carburettor design, engine cooling techniques and synthetic lubricants.

Inside This Book (Learn More)
First Sentence
Mechanically, the two-stroke engine is very simple, and unfortunately on too many occasions this apparent simplicity has fooled would-be tuners into believing that this type of power unit is easy to modify. Read the first page

5.0 out of 5 stars A 2-Stroke Bible 3 Jun 2001
The previous reviewer must have missed a chapter! But I agree that the examples are "old" - but this illustrates a wealth of experience. I have just completed "tuning" as outlined, the difference is noticeable to say the least. I lent my race bike to a fellow competitor, he found the performance of the engine "scary" as there was so much usable grunt on tap.
Technical - yes, but it needs to be.

I have the 1992 reprint of this book and as another reviewer said, the person who thought it should include a porting guide clearly missed Chapter 3 "Porting and cylinder scavenging". And yes, I agree the examples are old, but you have to remember this book was first published in 1983! Anyway, overall it's a great introduction to the basics and I feel a required read for anyone looking to tune a 2-stroke engine.

5.0 out of 5 stars Very good book (much better than I had expected) 20 Mar 2008
I bought this book after noticing that one review complained about the examples being old.
However, I was extremely satisfied with this book, and I concluded that all the other 2-stroke books I know, are outdated by this book some 20 years.

I bought this book together with "The high performance two-stroke engine" by John Dixon.
Graham Bell's book is "the book" for those interested in tuning.

The information on the latest engines is usually known by a few people, each of them usually knows about one specific engine, and the tricks are kept as a secret. Therefore no one should expect to find a book with very recent examples.

4.0 out of 5 stars Ok but old 1 Jan 2014

Format:Hardcover|Verified Purchase
I enjoyed the book, I was interested in getting a better understanding of 2 stroke tuning and this book has helped a lot.

I'm pretty sure 2 stroke tuning has moved on since this book was written but still gives a good background in the basics, a lot of the examples seem to be on old engines (does not really matter though I guess).

One thing I did learn from the book is I do not have enough money to be able to DIY tune a 2 stroke, the main thing I was interested in finding out about was porting with a view to doing some port tuning myself but this book has highlighted I am more likely to mess it up than make an improvement, I cannot afford the dyno runs and spare cylinders that would be required to actually make some headway in this complicated area.

So in summary if you want to learn a bit about 2 strokes then buy the book, if you want to tune your own 2 stroke I would recommend finding a specialist for your bike/engine unless you have loads of and time on your hands.

5.0 out of 5 stars Still valid.... 22 Feb 2012
Format:Hardcover|Verified Purchase
Okay, my interest is with 1970's motocross bikes, so this book is excellent in terms of approach and discussion. It makes some very sensible, easily readable, tuning tips and ensures that you tackle the obvious ones first, ie easiest with best performance improvement. Lots of experience and practice shows and knowledge of 70's and 80's two-stroke racing engines is obvious.

The book is based on practical know-how and experience. It has some theory (and mathematical equations), but is also full of common sense. Great read and lots on insight
