LIT-11616-YF-10 is the Yamaha part number for the Champ service manual, and the 1990 machine, code YFM100A, is one of the five model years it covers from 1987 to 1991.

Anyone maintaining one of these now is usually keeping it running for a younger rider, which makes the inspection and adjustment sections the most used part of the book. They state what to check, how often, and what figure counts as acceptable. Beyond that the volume carries the full engine and driveline procedures, fuel system work, brake and suspension specifications and complete wiring diagrams for electrical diagnosis.

Read YFM100A off your machine before ordering. A code match is what confirms the specifications you rely on belong to the ATV in your shop.
