1988–2002 Kawasaki KX Series KX60, KX80, KDX80, KX100 Factory Service Manual (P/N 99924-1094-07)

• 252-page PDF covering the 1988 base models, the 1989-1997 model supplement, and the 2000-2001 KX60 supplement. The final model-application table also lists the 2002 KX60-B18, while the late-model technical supplement itself is expressly written for B16 and B17.
• Documents major engine repair work, including compression testing, cylinder-head and cylinder service, piston and ring inspection, clutch disassembly, engine removal, crankcase splitting, crankshaft alignment, and transmission shaft, shift-drum, and shift-fork inspection.
• Separates model-specific fuel, cooling, and ignition procedures: carburetor fuel-level testing and assembly, reed-valve inspection, KX cooling-system pressure testing and water-pump service, plus CDI, stator-coil, ignition-coil, flywheel-magneto, and timing checks.
• Covers drum- and disc-brake repair, wheel and hub-bearing service, final-drive inspection, fork disassembly and oil setup, rear-shock and Uni-Trak work, and steering-stem bearing replacement and adjustment.
• Supplies exploded assembly views with torque, oil, grease, liquid-gasket, and locking-agent callouts, along with cable, hose, and wire routing plates and model-specific ignition wiring diagrams.
• Includes component torque tables, fluid specifications and capacities, carburetor settings, wear limits, chassis adjustment specifications, electrical test values, a model application chart with beginning frame numbers, and a system-by-system troubleshooting guide.

Exact Model Coverage

The base chapters apply to the 1988 KX60-B4; KX80-L1, M1, N1, and P1; and KDX80-C5. The first supplement adds the 1989 KX60-B5, KX80-L2/M2/N2/P2, and KX100-A1; the 1990 KX60-B6, KX80-L3/M3/N3/P3, and KX100-A2; and KX60-B7 through B13 for 1991-1997. KX100 procedures use the KX80-N1 base instructions except where the supplement gives KX100-specific data.

Later coverage is limited to KX60-B16 (2000), B17 (2001), and the B18 (2002) model-application entry. KX80 and KX100 coverage stops with the 1990 model codes, while the KDX80 material is specific to the 1988 C5. These are not blanket 1988-2002 ranges for every model named on the cover. The cooling chapter is marked KX models only; the KDX80 is air-cooled.

Kawasaki states that the manual was designed primarily for trained mechanics in a properly equipped shop. It also contains enough detail for owners with basic mechanical, tool, and workshop knowledge to perform basic maintenance and repair, while advanced work still assumes suitable measuring equipment and special tools.

Factory Repair Depth

This service manual goes well beyond routine maintenance. The bottom-end section covers case separation and assembly, crankshaft removal, runout and alignment checks, transmission gear orientation, and shift-component wear inspection. Crankshaft disassembly and reassembly are specifically identified as shop work requiring the necessary equipment and close-tolerance capability. The supplement adds KX60 clutch-release lever angle and shim checks, revised KX80/KX100 clutch assembly details, and model-specific transmission and suspension changes.

Brake coverage distinguishes the KX60/KDX80 drum systems from the KX80/KX100 hydraulic disc systems. It addresses brake-panel assembly, cam and lining inspection, caliper and master-cylinder repair, pad and disc checks, fluid replacement, hose service, and brake-line bleeding. Suspension chapters cover fork air pressure and oil-level setup, fork teardown and seal replacement, KX80/KX100 rear-shock spring, damping, and nitrogen service, swingarm work, and Uni-Trak bearing inspection.

Two assembly cautions are especially important. The Electro Fusion cylinders cannot be bored or honed; a worn or damaged cylinder must be replaced. On liquid-cooled KX models, water-pump shaft direction and lubrication also matter, because incorrect handling can peel or prematurely wear the oil-seal lips.

Specifications, Tools, and Visual References

Factory data is organized by model and system, including jetting and service fuel levels, compression ranges, clearance and wear limits, fork and shock settings, torque and locking-agent tables, and CDI and stator resistance charts. Listed special tools include the Crankcase Splitting Tool Set 57001-1098, Crankshaft Jig 57001-1174, Flywheel Puller 57001-252, and Bearing Driver Set 57001-1129.

Useful visual references include the KX60/KDX80 and KX80 ignition wiring diagrams, the KX cooling-system flow view, engine and transmission exploded views, front and rear brake assemblies, and Uni-Trak suspension layouts. The appendix adds fault-isolation guidance for starting problems, poor running, overheating, clutch and shifting faults, abnormal noise, suspension behavior, steering, and braking. Fuel, brake, cooling, ignition, and nitrogen-charged shock work should be carried out with the ventilation, pressure-release, and protective measures specified in the manual.
