On a 2018 L-TX LE the code is SW1NLLJL. The manual is LIT-12618-03-50, Yamaha's single volume for all twenty 2018 Sidewinder models, B-TX through X-TX, including the 50th anniversary sleds and the Early Build variant.
Four 2018 models carry L-TX LE in the name in one form or another, which is a good argument for checking the code rather than the badge. The manual identifies affected models by code wherever a specification is not common to the range.
Technically the book gives what a technician needs and nothing softened for a general audience: maintenance intervals, engine and turbocharger overhaul with torque and clearance figures, fuel-system and electrical testing with expected values, clutch and drive-belt specifications, slide rail and track setup, brake and steering procedures, and complete wiring diagrams.
