1980 Yamaha TT250 Service and Repair Manual

Part number LIT-11616-01-92 is the factory service reference for the TT250, and the 1980 machine it applies to carries the code TT250G. Yamaha's coverage runs across the 1980, 1981 and 1982 model years in the one volume, which reflects how short and how consistent that production run was.

Working on a bike of this age, the value of the original document is that it states what the factory actually specified rather than what convention has since decided. Wear limits, shim and clearance figures, assembly order, carburettor settings and the wiring as originally drawn are all there in their first form.

Restorers tend to use it as the arbiter when two rebuilt examples disagree.

Before ordering, confirm LIT-11616-01-92 and check the TT250G code on your frame. Those identifiers matter more than the year painted on the tank.
