Precision Motorcycle Diagnostics
Serving Charlotte & Surrounding Areas
Comprehensive Diagnostic Expertise
Electronic and mechanical systems assessed
Motorcycle, ATV, and quad diagnostics demand accurate data and methodical testing. Motor Mouth Repair uses factory-grade scan tools, OEM service information, and lab scopes to read fault codes, monitor live sensor data, perform actuator tests, and verify operation of ECU/ECM, fueling, ignition, charging, starter, ABS, traction control, ride-by-wire, and CAN bus systems.
From compression and leak-down testing to fuel pressure checks and throttle body synchronization, we combine electronic and mechanical inspections to pinpoint issues without guesswork. We are in business for 4 years and exclusively service motorcycles, ATVs, and quads—carbureted or fuel-injected, stock or modified.
From symptom to root cause
We begin with a detailed intake: symptom review, riding conditions, recent work, and modifications. Next, we perform a systematic inspection—battery and charging tests, visual harness checks, ECU code scans, live data analysis, wiring diagram–guided pinpoint tests, sensor verification, and component actuation. When appropriate, we validate results with a controlled test ride.
You receive clear, written findings with photos or data logs, a plain‑English explanation, and a prioritized action plan. We avoid the parts‑cannon approach by confirming faults before recommending repairs. Typical initial diagnostics require 60–90 minutes; complex electrical issues can take longer depending on access, intermittent behavior, and model‑specific systems.
Symptoms, causes, and solutions
No‑start, hard‑start, or stalling complaints are often tied to weak batteries, parasitic draws, failing stators or regulator/rectifiers, and starter circuit faults. Fueling problems—clogged injectors or jets, failing pumps, restricted filters, or vacuum leaks—can cause rough idle, surging, and misfires. We also verify ignition coils, plugs, timing signals, and sensor inputs such as TPS, MAP, IAT, and O2.
Performance issues like hesitation, bogging, or loss of power may stem from incorrect throttle calibration, dirty throttle bodies, air leaks, or exhaust restrictions. Warning lights and electronic rider aids (ABS, traction control, quickshifters, ride modes) can flag wheel speed sensor faults, tone ring damage, or CAN communication errors. Overheating concerns are assessed through cooling fan operation, thermostat function, and coolant flow checks.
Intermittent electrical gremlins often trace to corroded connectors, chafed wiring, weak grounds, or added accessories drawing excessive current. We diagnose stock and modified machines, EFI and carbureted alike, across sport, touring, cruiser, and off‑road categories. We only service motorcycles, ATVs, and quads; we do not work on cars, trucks, or watercraft.
