What a book like this gives you is order. The engine chapter does not simply list parts; it takes the motor out, splits it, measures it against stated limits and puts it back together, with the torque figure given at each fastener. The electrical chapter works circuit by circuit with a meter and a diagram. The chassis chapter covers the air suspension, the forks, the brakes and the steering head in the same methodical way.
Periodic maintenance, valve clearance and carburetor work sit ahead of all that, which is where most owners spend their time.
Order LIT-11616-XV-14, and check the frame plate reads XVZ1300DUC.
