1988 Yamaha FZR400 Service and Repair Manual

Yamaha covered three seasons of the FZR400 in one volume, LIT-11616-07-23, spanning 1988, 1989 and 1990. The 1988 machine carries the code FZR400SUC.

Match that code on the frame plate first. Where the years differ the book gives the figures separately, so nothing is averaged across the range.

What you get

• Engine and transmission service in factory sequence, with inspection limits
• Torque specifications
• Carburettor and ignition settings
• Brake, suspension and wheel procedures
• Wiring diagrams and electrical test values
• Troubleshooting organised by symptom

A sports machine of this era is usually on its second or third engine by now, and the wear-limit tables are what tell you whether the parts in front of you are within specification or merely still assembled.
