For the first-generation Warrior, Yamaha published LIT-11616-RS-W0. The 2003 bike is model code XV1700PCR.
This volume covers the 2003, 2004 and 2005 model years, and it takes in the Road Star Midnight Warrior as well, which shared the platform. Having both in one book is practical: when you are chasing a superseded part or comparing a setting, the answer is on the same page rather than in a manual you do not own.
The material is what a dealer technician was given. Engine and chassis work is set out in factory sequence with the tightening torques, clearances and service limits included, so you are not estimating a figure on a critical fastener. Wiring diagrams support electrical diagnosis, and the troubleshooting sections are arranged by symptom. The periodic maintenance schedule is there too, which matters on a bike now well past its first decade.
Verify XV1700PCR against your frame code before ordering anything.
