Comprehensive Repair Manual for Suzuki LT300E QuadRunner 300 (1987-1989)

Suzuki LT300E / LT-F300 — Service Manual (1988–1989 Model Coverage)

Coverage is tied to the Suzuki LT300E family and the LT-F300 series pages called out in the group index, with separate model-year tracks for ’88 and ’89. Fit is easy to confirm up front: the VIN stamping and engine serial locations are specified, and the early specification pages consolidate dimensions, engine architecture, gearing, chassis geometry, and capacity data in one place.

Models and year tracks listed

• LT300EJ (’88 model)
• LT300EK (’89 model)
• LT-F300 (’88 model)
• LT-F300 (’89 model)

Where the fast “fit” signals live

The identification pages specify:

• VIN stamping: left frame pipe
• Engine serial number: crankcase
  Those two markings are the primary match points when you want to ensure the manual aligns with the correct LT300E build family.

Electrical and chassis data density (what’s documented)

Electrical specs include SUZUKI “PEI” ignition, plug families split by market, battery ratings (U.S. vs other), and lighting wattage (e.g., 12V 45/45W headlight). Chassis pages add steering angles (inside/outside), caster/trail, camber, tire sizing, and load-indexed tire pressures with a stated vehicle load capacity limit.
