Half the battle of owning a bike is learning how to fix the bloody thing. Increasing your understanding isn't always easy. Workshop/aftermarket manuals are light on the how and why, and are far from comprehensive in their maintenance info in my experience. There's a wealth of info on the net, but much of it is poorly explained and illustrated. New title "How to repair your motorcycle" is a godsend. Starts with the basics, but even experienced spanner heads can learn something here. From the very basic "oil and filter change", "Adjust your chain" etc... handy tuning info, such as "installing jet kits/power commander", "installing an exhaust" to the baffling arcane mechanica I've been hanging for, such as adjusting valves, servicing the carbs etc... Name a project, it's in this book. Fuel system, engine, electrical, cooling, drivetrain, suspension, frame, wheels, brakes, exhaust, cleaning. Yep, covered. How many motorcyclists truly know how to change a tyre? This should be mandatory reading for all learners. Even if you don't get into the heavy business, it'll give you a greater understanding of your machine and help you in the event of a breakdown. Nicely illustrated, and impressively comprehensive. Could have been improved with an explanation on fixing stripped threads and rounded bolts. As a supplement to your workshop manual, this is essential reading.
