1985–1988 Kawasaki ZL900/ZL1000 Eliminator Service Manual Supplement (P/N 99924-1077-51, ISBN 1 85960 355 6)

• 613-page, three-PDF package — the 152-page first-edition Kawasaki ZL900-A1 factory supplement dated January 1985; the 187-page second-edition ZL900/ZL1000 factory supplement dated March 1986, P/N 99924-1077-51; and the 274-page Haynes ZX900/1000/1100 service and repair manual, ISBN 1 85960 355 6.
• Factory application covers the 1985 ZL900-A1, 1986 ZL900-A2, and 1987 ZL1000-A1, with beginning-frame-number data for each model. The Kawasaki application table does not list a 1988 Eliminator.
• Covers Eliminator-specific fuel and cooling work, engine top-end and engine removal, clutch and lubrication service, and model-specific Keihin CVK32/CVK34 carburetor data.
• Details major shaft-drive repair work, covering final gear case and front bevel gear removal, disassembly, bearing-preload setup, backlash and tooth-contact adjustment, propeller-shaft service, and related inspection.
• Addresses front and rear suspension, swingarm, steering, wheels and brakes, plus alternator and regulator/rectifier diagnosis, starter and cooling-fan circuits, meter checks, warning systems, junction-box inspection, and model-specific wiring.
• Supplies exploded assembly views, circuit and routing drawings, troubleshooting material, special-tool references, component torque data, fluid capacities, wear limits, electrical test specifications, and adjustment tables.

Factory Coverage and Scope

The two Kawasaki publications are factory supplements, not stand-alone overhaul manuals. The 1985 first edition is dedicated to the ZL900-A1. The 1986 second edition retains the ZL900-A1 material, adds ZL900-A2 application, and includes a separate ZL1000-A1 chapter for model-specific differences. Both concentrate on construction, service, and repair procedures that depart from the ZX900 platform. The later supplement maps coverage to these beginning frame numbers: 1985 ZL900-A1, JKAZL2A1xFA000001 or JKAZL2A1xFB500001; 1986 ZL900-A2, JKAZL2A1xGA002301 or JKAZL2A1xGB504701; and 1987 ZL1000-A1, JKAZLCA1xHA000001 or JKAZLCA1xHB500001. In those identifiers, x is the frame-number digit that changes from one motorcycle to another.

Both factory supplements specify the Kawasaki ZX900 Motorcycle Service Manual P/N 99924-1048-01 as the required base publication. That OEM book itself is not included in this set. Where a ZL chapter says “Base Manual,” it is the publication being referenced. The included Haynes PDF is an independent publication covering the related liquid-cooled ZX900, ZX1000, and ZX1100 fours; it is not the Kawasaki factory base manual named in the supplements. That distinction matters whenever a ZL section sends the mechanic to the base manual for the complete procedure.

Documented System Coverage

Fuel-system material identifies the ZL900’s Keihin CVK32 setup and the ZL1000’s CVK34 configuration, then covers throttle and choke controls, idle-speed inspection, fuel-tank removal, fuel-tap and cap inspection, and California evaporative-emission components and hose routing. Cooling pages address coolant service, radiator and fan removal, reservoir routing, thermostat work, and water-pump access. Full carburetor overhaul and synchronization procedures are among the operations directed back to the base manual.

Engine and clutch sections cover compression measurement, clean-air equipment, cylinder-head cover and head removal differences, exhaust-system service, clutch removal and installation, hub disassembly, spring-plate setup, friction and steel plate inspection, oil-pan work, and complete engine removal and installation. The Haynes volume adds general ZX-family overhaul and fault-finding coverage beyond the ZL-specific changes.

The final-drive chapter carries unusually detailed Eliminator-specific repair coverage. It details final gear case teardown and assembly, pinion service, tapered-roller-bearing preload, final and front bevel gear backlash, tooth-contact evaluation, propeller-shaft work, damper-cam service, and front bevel gear case repair. It also flags expensive assembly errors: the ring and pinion are factory-lapped as a matched set, misplaced shims can alter contact and backlash, excessive preload can damage the bearings, and torch-heating the gear case can warp the housing.

Chassis coverage reaches beyond wheel removal. It includes front fork oil and air-pressure service, fork disassembly, rear shock adjustment and oil filling, swingarm removal and alignment, steering inspection, rear brake adjustment, and bearing inspection. Electrical chapters cover alternator removal and troubleshooting, regulator/rectifier testing, ignition and starter systems, reserve lighting, cooling-fan operation, meters and tachometer diagnosis, temperature warnings, brake-light switches, the junction box, and harness routing.

Diagrams, Tools, and Factory Data

Especially useful references include the Engine Oil Flow Chart, final gear case and front bevel gear exploded views, correct and incorrect tooth-contact pattern charts, the Electric Starter Circuit, and model-specific ZL wiring diagrams. Tool callouts identify equipment such as the pinion gear holder 57001-1165, dial gauge holder 57001-1049, damper cam holder 57001-1025, bearing driver set 57001-1129, and oil-seal and bearing remover 57001-1058.

Specification sections provide component torque tables, fastener checks, lubricant and fluid-capacity data, inspection limits, preload and backlash adjustment information, and electrical test values. For engine, fork, wheel, brake, and shaft-drive repair, the motorcycle must be securely supported before major components are loosened; the cooling system should be depressurized, and open fuel-system work kept away from ignition sources.
