1987 Yamaha MOTO-4 200 Service and Repair Manual

Coverage for the 1987 MOTO-4 200 sits inside Yamaha LIT-11616-YF-20, a manual written to span 1985 through 1988 and to include the MOTO-4 alongside the 200. The 1987 model code is YFM200DXT.

Much of what goes wrong on a quad of this age is adjustment rather than failure, and the book is specific about both. It gives the valve clearance figures, the carburettor settings, the ignition specification, the brake wear limits and the maintenance intervals, then the full teardown procedures for when something really is worn out.

Torque values accompany the reassembly steps, exploded views identify parts, and the electrical section carries the complete wiring diagram. Match YFM200DXT to your own machine first, since the codes across these four years read almost identically.
