For 1993 the YZ250 was built as model code YZ250E, and Yamaha documented it in service manual LIT-11626-08-62.
A good number of these bikes are still ridden, and the manual reflects how they get used. Maintenance items come with intervals and methods. Rebuild chapters come with measurement points, service limits and torque figures. Suspension, fuel and ignition each have their specifications, and the electrical section carries the wiring diagram for the harness as it left the factory.
One ordering note worth repeating. The YZ250 model code changed nearly every year, and the letter suffix is not a reliable guide on its own, so read the full code from the frame label and match it to YZ250E before buying. Getting the correct year's book is the difference between working to real figures and working to approximate ones.
