Suzuki LT-F400 KingQuad 2008-2013 Service Manual

Heavy Equipment Manual's own factory documentation confirms this exact range genuinely spans a real fuel-system transition: "has the updates for fuel injection on 2010-2013 models. Covers all model variations including EFI models from mid-2010 on" — meaning a 2008-2009 example runs a carburetor while a mid-2010-or-later unit runs electronic fuel injection, a genuine mechanical distinction worth confirming against the specific model year before assuming universal parts interchange.

Power comes from a 376cc single-cylinder engine, an 82.0mm bore, delivering drive through Suzuki's Quadmatic automatic transmission with a variable primary reduction ratio spanning 2.938 to 0.813. The LT-F400 designation covers Suzuki's manual-shift, foot-shift KingQuad 400, distinct from the LT-A400 automatic variant covered in the same combined factory manual.

RepairLoader's own confirmed 2008-2009 factory specification sheet lists a 16.0-litre (4.2 US gallon) fuel tank, an 880mm front track, and a 900mm rear track. The manual covers comprehensive engine mechanical work including cylinder, piston, crankshaft, camshaft, and valve train service, alongside dedicated lubrication, fuel, ignition, starting, and charging system chapters — genuinely thorough coverage across both the carbureted and EFI configurations this range spans.

eManualOnline's own confirmed listing runs to 518-714 pages depending on edition, with step-by-step instructions, exploded-view illustrations, and manufacturer-recommended troubleshooting charts. RegulatorRectifier's own confirmed aftermarket fuel controller listing for this exact model range spans 2008 through 2013, adjustable from -4% to +10% fuel mapping across seven settings — genuinely useful context confirming the EFI system's tunability once it arrived mid-way through this production span.

This factory service manual covers the procedures, torque specs, and diagrams needed to keep a 2008-2013 LT-F400 KingQuad running the way it was built to.
