Who can tell me of a good book, written in layman terms for the beginner, about an inline-4 engine with a shaft drive. I have learned a lot from the Haynes Owner Workshop Manual. I am practicing on a 2-stroke Suzuki, and it is easy enough to understand. Yet, I am having way to much fun riding my XJ750J to just tear into her to find the knocks and pings. I need a better understanding of how the engine, tranny, and everthing inbetween works together. I can not seem to grasp the big picture. Help, please. B)
