Description

Kawasaki Eliminator 125 Service Manual 1998-2007 – BN125-A1 to A8

This is the complete Kawasaki Eliminator 125 service manual covering the BN125 model series from the first A1 machines of 1998 through to the A8 and later variants built up to 2007. It is the same workshop reference a Kawasaki-trained technician would reach for, covering every major system on the Eliminator 125 – engine, fuel, clutch, transmission, brakes, suspension, steering, frame and electrical – with the procedures, torque values and service limits required to maintain and rebuild the machine properly. Every chapter is written for the 124 cc SOHC air-cooled single-cylinder engine and the chassis it sits in, so the numbers and procedures apply directly to the machine in front of you.

Why This Kawasaki Eliminator 125 Service Manual Matters

Torque values matter. Valve clearances matter. Crankshaft runout tolerances matter. Get them wrong on a 124 cc single and you get burnt valves, seized pistons, kinked cam chains and a motorcycle that will not run right again. This manual prints the numbers exactly as Kawasaki set them – valve clearance inlet 0.08 ~ 0.12 mm and exhaust 0.15 ~ 0.19 mm, cylinder compression usable range 960 ~ 1 470 kPa, crankshaft runout service limit TIR 0.07 mm, drive chain 20-link length service limit 259 mm, brake disc service limits, spark plug gap 0.7 ~ 0.8 mm, and hundreds more – so you can work to the manufacturer’s spec instead of guessing.

It also tells you the order things come apart and go back together. The camshaft sprocket must align with the timing mark at TDC on the compression stroke. The camshaft chain tensioner is a non-return type – once the push rod moves out it will not go back in without resetting. The crankshaft jig goes between the flywheels before pressing into the crankcase. The oil pump rotors are filled with oil before assembly. The rear hub bearings must be bottomed out. The drive chain clip must face the correct direction. Small details like these separate a reliable rebuild from an expensive mistake.

Who This Manual Is For

Owners who service their own Eliminator 125. Home mechanics tackling a top-end refresh, clutch replacement, brake overhaul or electrical fault. Independent workshops that need the factory procedures and torque values on hand. Anyone doing a restoration or rebuild of a BN125-A1 through A8 machine. If you are diagnosing a no-start, a charging fault, a carburetor issue, a slipping clutch or a worn drive chain, the relevant chapter is here with the exploded views, wiring diagrams, special tool numbers and specification tables you need.
