A 1988 long-track Bravo is coded BR250TM. Its factory service manual carries Yamaha part number LIT-12618-BR-01, and those two identifiers together are how you confirm you have the right reference for the sled in front of you.
Coverage is wide rather than narrow. Yamaha's Bravo book spans 1984 through 2000 and 2007 through 2011, and it includes the standard Bravo and the Bravo T as well as the LT. Working on a late-eighties machine, you get the specifications for the years around it too, which matters when a component was shared or superseded.
Procedures cover maintenance intervals, engine and clutch service, power train and suspension work, and electrical diagnosis, with torque values quoted where a fastener is critical and wiring diagrams provided for the harness.
