For the 1993 RAZZ, coded SH50E, the repair reference you want is Yamaha LIT-11616-05-80. One book, fifteen model years: Yamaha wrote it to cover the RAZZ from 1987 right through to 2001, so the 1993 machine sits comfortably in the middle of its scope.
Inside
Maintenance schedules and the adjustments that go with them. Engine, drive and chassis procedures laid out step by step. Torque specifications. Full wiring diagrams. Diagnostic tables that start from what the scooter is doing wrong and walk back to the cause.
A word on fitment. The SH50E code is what separates your scooter from the SH50D ahead of it and the SH50F behind it, and the manual uses those codes where a procedure or a specification changes. Check the code on the frame, match it against the text, and you will not fit the wrong part.
