Craftsman Motorcycle Vehicles Maintenance study guide
Craftsman Motorcycle Vehicles Maintenance · Work through your exam, one topic at a time.
The Craftsman Motorcycle Vehicles Maintenance credential is a multiple-choice assessment aimed at technicians who service and repair motorcycles rather than at riders learning basic ownership skills. It suits working shop technicians, apprentices preparing for a maintenance role, and career changers moving from automotive or small-engine work into two-wheeled service. The Craftsman Motorcycle Vehicles Maintenance study guide has 8 sections and about 2,564 words.
01Motorcycle Engine Systems Diagnosis and Repair
This domain tests whether you can move from a complaint to a measured cause on four-stroke motorcycle engines: sealing integrity, valve train geometry, cam timing, lubrication and mechanical noise. Measure valve clearance cold, with the lobe on its base circle, using a feeler gauge between cam and bucket/shim.
370 words, about 2 min02Fuel, Ignition, and Emission Control Systems
This domain covers carburation, fuel injection, spark delivery and the hardware that keeps exhaust emissions in check. Carburettor circuits are throttle-position dependent: pilot circuit (0–1/8), slide cutaway and needle (1/8–3/4), main jet (3/4–full).
322 words, about 2 min03Transmission, Clutch, and Final Drive Service
This domain follows the torque path from crank to rear wheel: clutch stack, shift mechanism, and chain, belt or shaft final drive. Wet multiplate clutch: measure total stack thickness and each friction plate against spec, check spring free length, and verify lever free play (typically 10–20 mm at the perch) so the release bearing is not preloaded.
350 words, about 2 min04Braking Systems and Hydraulic Service
This domain covers hydraulic braking: fluid, bleeding, friction pairs, and ABS service. Glycol fluids (DOT 3, 4, 5.1) are hygroscopic; absorbed water lowers the boiling point and gives a lever that fades when hot or feels spongy.
322 words, about 2 min05Suspension, Steering, and Wheel Alignment
This domain covers spring rates, damping, steering geometry and the measurements that prove them. Set sag first: measure rear static and rider sag with the bike loaded; adjust preload to hit spec, then set rebound and compression clickers to baseline before evaluating.
317 words, about 2 min06Electrical Systems and Electronic Controls
This domain covers measurement practice, charging and starting circuits, and network diagnostics. Ohm's law is the working tool: V = I × R.
307 words, about 2 min07Frame, Chassis, and Bodywork Inspection
This domain covers structural inspection, damage assessment and correct refastening after repair. Check frame alignment at the steering head and swingarm pivot; a bent frame on a road bike is replaced, not straightened.
296 words, about 1 min08Preventive Maintenance, Lubrication, and Tune-Up
This domain covers the service schedule, correct fluids, and the checks that prevent roadside failures. Use the manufacturer's intervals as the baseline and match oil to spec: JASO MA/MA2 for wet clutches and the viscosity for ambient temperature.
