Service coverage for the 1992 Blaster, code YFS200D, is found in Yamaha manual LIT-11616-07-20.
What the manual spans
1988 through 2001, all in one book. Yamaha added to it rather than replacing it, so a 1992 machine is fully documented and the later revisions are visible alongside.
The procedures cover periodic maintenance and adjustment, engine removal and overhaul with inspection against service limits, carburetor and fuel system work, clutch and transmission, final drive, brake and wheel service, steering and suspension, and the complete electrical system with wiring diagrams. Tightening torques are printed with the steps they belong to instead of being collected elsewhere, and the troubleshooting chapter is the factory's own, working back from the symptom.
Confirm YFS200D against your machine before ordering.
