2023 Yamaha SIDEWINDER L-TX GT EPS Service and Repair Manual
Part number LIT-12618-03-90 is Yamaha's 2023 Sidewinder service manual. The L-TX GT EPS it covers is coded SW1NLGPPT, and the same volume documents the L-TX LE EPS, L-TX SE, S-TX GT EPS, SRX LE EPS, X-TX LE and X-TX SE.
On a recent sled still under warranty the diagnostic chapters tend to get used before anything comes apart. Fault codes, sensor values and test sequences are given as Yamaha wrote them, which is what makes it possible to tell a genuine failure from a connector problem.
Beyond diagnosis the manual carries the full service content: maintenance intervals, engine and turbo procedures with torque and clearance specifications, power steering service, clutch and driveline data, suspension and track adjustment, brakes, steering and wiring diagrams for the complete machine.
