1990 Yamaha PHAZER Service and Repair Manual

Ten model years of Phazer are documented in LIT-12618-PZ-50, from 1990 through 1999, and the electric-start Phazer and the Phazer II are included alongside the base machine. The 1990 sled carries model code PZ480EP.

The long coverage is the point. Parts and procedures changed little across the run, so Yamaha handled the whole family in one volume and noted the year-by-year differences in the tables. Look up PZ480EP and the specifications are the ones written for that sled.

Content is what a shop needs: disassembly sequences, inspection limits, torque values, carburetion and ignition settings, wiring diagrams and the maintenance schedule.

Sections cover identification and general specifications, the engine and its fuel system, the clutch and drive components, the chassis and suspension, and the electrical system. On a sled that has changed hands several times, the maintenance tables also serve as a checklist of what may never have been done.
