For 1991 the code is YFM250B, and that is what to check against the frame before you trust a torque figure or a clearance.\u003c\/p\u003e\u003cp\u003eFactory manuals from this period walk through a job in the sequence a dealer technician used, including the checks that decide whether a part is reusable. Engine work, the transmission and final drive, brakes, steering and suspension, and the electrical system each get their own chapter, with exploded views for parts identification.\u003c\/p\u003e\u003cp\u003eFluid specifications and capacities are listed in the opening chapter alongside the maintenance intervals.
