The author viewed 2 stroke engines with contempt until he was persuaded by two of his friends to prepare a 250cc Bultaco motorcycle for National Motocross Championship which ended up finishing 3rd with a B grade rider on board. Here's what Graham Bell says:
"From then on the challenge has not abated as I have strived to unravel the mystery of what makes a two-stroke tick. Instead of looking on the two-stroke with contempt, I now view this little marvel with fascination. Four-stroke engine development has just about reached its peak, but there is much yet to be learned about the two-stroke power unit."
Two Stroke Performance Tuning is a very thorough book aimed at understanding and tuning two stroke engines for maximum power and reliability.
