Craftsman Motorcycle Vehicles Maintenance study plan

Diagnose four-stroke no-start and low-compression faults by sequencing a compression test, leak-down test, and valve clearance check on at least three practice engines.

Measure cylinder bore taper and out-of-round with a bore gauge and decide whether to hone, rebore, or replace the cylinder.

Time camshafts to the crank on a shim-under-bucket and a rocker-arm engine, then verify valve timing marks against the service specification.

Trace oil pressure loss from gauge reading to pump, relief valve, and bearing clearance, and rank the likely causes in writing.

Inspect and measure valve seats, valve stems, and springs against wear limits, then grind or replace as the measurements dictate.

Set up and adjust a carburetor for idle mixture and synchronization on a multi-cylinder engine using vacuum gauges.

Test fuel pump pressure and flow, then trace a lean or rich condition to injector, regulator, or intake leak.

Read spark plug color and electrode wear to classify mixture and ignition faults on four sample plugs.

Diagnose a misfire by isolating spark, fuel, and air with a spark tester, noid light, and compression results, in that order.

Measure ignition coil primary and secondary resistance and interpret the readings against specification.

Check charging voltage and battery condition at idle and 3,000 rpm, and explain how low voltage corrupts sensor signals.

Verify emission control devices such as the EVAP canister, PCV, and oxygen sensor heater circuit function and identify faults that would fail an inspection.

Measure clutch plate thickness, spring free length, and basket notch wear, then decide to reuse or replace each component.

Adjust clutch cable free play and hydraulic clutch engagement on at least two different motorcycle layouts.

Set drive chain slack, check sprocket tooth wear, and verify rear wheel alignment with a string or laser method.

Drain and refill shaft-drive final drive oil and inspect the spline and seal condition against specification.

Bleed a hydraulic brake system by both manual and vacuum methods and confirm a firm lever with no sponginess.

Measure brake pad thickness, rotor runout, and rotor thickness, and compare each against the service limit.

Diagnose a spongy lever or dragging caliper by isolating master cylinder, line, caliper piston, and contaminated fluid.

Inspect brake lines, banjo fittings, and ABS modulator plumbing for leaks, chafing, and correct routing.

Measure fork sag, set static and rider sag, and adjust rebound and compression damping to a target setting.

Inspect steering head bearings for notchiness and set bearing preload to specification.

Check wheel runout, spoke tension, and tire wear pattern, and decide whether a wheel needs truing or replacement.

Test a charging system end to end: stator output, regulator rectifier output, and parasitic draw, then interpret the results.

Read a wiring diagram and locate a fault in a lighting or starting circuit using a multimeter and voltage drop testing.

Test a CAN or sensor network fault by checking reference voltage, ground integrity, and signal at the ECU connector.

Inspect a frame and swingarm for cracks, corrosion, and previous repair, and document findings with a measurement record.

Check steering alignment and frame straightness after a drop by comparing reference measurements side to side.

Perform a full scheduled service to the manufacturer interval: oil and filter, air filter, plugs, fluids, and fastener torque checks.

Build a preventive maintenance checklist covering tire pressures, brake fluid age, chain lube, and battery health.

Complete a timed 60-question mixed practice exam and review every missed item against the source material.

Re-test the three weakest domains from the practice exam and close each gap with a written summary of the corrected concept.
