1988 Yamaha ROUTE 66 Service and Repair Manual

The little XV250 has had a long life under several names, and Yamaha's LIT-11616-XV-25 is the manual that follows it. For 1988 the Route 66 is model code XV250U.

Look at the coverage and you see why this book stays in print culturally if not commercially: it spans 1988, 1989 and 1990, then picks up again across 1995 to 1999 and 2001 to 2005, and it includes the Virago 250. Yamaha kept the machine fundamentally the same for that long, so one set of procedures genuinely serves a bike built seventeen years apart from another.

You get factory tightening torques, inspection criteria and service limits, teardown and reassembly in sequence, the maintenance schedule, wiring diagrams and troubleshooting arranged by symptom.

Confirm XV250U against the code on your frame. On a bike with this many model years in one book, that check is what keeps you on the right table.
