2019 Yamaha SRVIPER L-TX Service and Repair Manual

Yamaha published LIT-12618-03-57 for the 2019 model year, and the L-TX it documents carries the code SR1NLKS. Unlike the 2018 book, this one stands on its own rather than spanning several trims.

The material is dealer-level. Engine work comes with torque sequences and clearance limits, the fuel injection chapter includes diagnostic procedures rather than general advice, and the electrical section carries the wiring diagram in full. Drive clutch, chaincase, track tension, and front and rear suspension each get their own treatment, and the periodic maintenance schedule is the one Yamaha specified for the sled when new.

Match SR1NLKS to the code on your machine before buying. Yamaha reused the L-TX name across model years with different codes behind it, so the code and the part number together are what confirm you are looking at the right book.
