The Amazon book description says 450 pages, but there are actually 331. Nevertheless, I have found this repair manual to be invaluable. I have been able to successfully do a tune-up, change radiator fluid, oil change, air and oil filter replacements, valve clearance measurements and then swapping out shims to adjust, replacing the cam chain tensioner (duhicky) and then adjusting (big job), upgrade the fork springs to Progessive springs, replace the front brake line, AND a myriad of other tweaks and adjustments thanks to this thorough user-friendly manual.
There are a plethora of clear photographs that include graphic arrows and are numbered and then referenced in the detailed how-to sections of the book. Exploded diagrams are large and clear with parts numbered and then listed by name. Trouble-shooting diagnostic steps are well illustrated in tables. And there are dedicated pages about special tools for specific jobs, metric conversion tables for specs, fasteners & torque, as well as four pages of colored wiring diagrams.
But besides just being thorough, the main thing I like about this manual is how easy it is to use. It provides a "Quick Reference Data" page containing all the info that you always need to know but can't ever remember -- oil capacities, spark plug gap and torque, tire pressure, drive chain play, serial numbers and more -- all on one page that you can copy and tack to the wall. Also, the routine maintenance procedures for the entire bike are covered in a single place, Chapter 3, so you don't have to waste time jumping around to other chapters that are dedicated to the details of each system.
Servicing, repairing and maintaining a bike is a challenge for me, but with the right information quickly available, I have found that most jobs can actually be enjoyable. This Clymer manual for the KLR has helped make that possible.
